Regular Expression Sequences Apply any number of search terms of regular expressions sequentially or concurrently. Complex search and replace operations often require multiple steps. Use PowerGREP to execute as many steps as you want in a single operation. Run the steps concurrently (search matches won't overlap), or sequentially (replacements cascade onto the following steps). Save all steps into a single PowerGREP Action for instant reuse. Similarly, while searching or collecting data, use a list of search terms or regular expressions to find files matching different criteria, or to extract disparate information from each file.

Slice and Dice Files Any Way You Want Limit your search to specific file sections. When updating web sites, limit the search and replace to HTML tags, or even specific HTML tags, or alternatively, skip HTML tags. When programming, search through only comments and/or strings, or alternatively, skip comments and/or strings. Use as many regular expressions as you want to section files. Split files into records before searching. Instead of searching whole files at once, or line by line, split files into whichever record or block structure the files are formatted with. Specify record delimiters, or use regular expressions to match the records themselves. When sectioning files or splitting them into records, you can work with the sections as a whole. Require search matches to span complete sections, collect or replace whole records, or return those records in which the search terms cannot be found.

Adapt Search Matches before Substitution or Collection Post-process replacement text or text to be collected. Often, a search match isn't in the format you want it to be. PowerGREP's unique "extra processing" feature allows you to perform additional search and replace steps on each search match. E.g. when processing web logs, replace URL-encoded characters when extracting search engine keywords from referrer URLs.

Work Safely with Automatic Backup and Undo History Stay safe with the permanent Undo History. When PowerGREP overwrites a file, it will create a backup copy of the original using your preferred naming style, placing the backup in your preferred location. If you change your mind about a particular action, undo it with just one click in PowerGREP's Undo History. Even after you've closed PowerGREP or rebooted your computer. Or, with another click, delete all backup files when they're no longer needed.

Compatible with a Wide Range of Software PowerGREP is compatible with a wide range of software in various ways. Use industry standard regular expressions to specify text patterns, compatible with Perl, Java, .NET and many other applications and programming languages. Use the skills you already have with PowerGREP, or use your new-found skills in many situations. Where most Windows grep tools support only Windows text files, and probably Unicode, PowerGREP supports a wide range of both current and legacy text file encodings: all Windows code pages, various Unicode transformations, all ISO8859 character sets, most MS-DOS and PC DOS code pages, ECBDIC IBM mainframe code pages, KOI8, etc. Search through, edit and create text files in any of these encodings. Configure PowerGREP to use specific encodings for certain file types. PowerGREP can also decode a variety of popular proprietary file formats: Microsoft Word documents (.doc and .dot files), Adobe Acrobat documents (.pdf files), Microsoft Excel spreadsheets (.xls files), Lotus 1-2-3 spreadsheets (.wks and .wk1 files) and Quattro Pro spreadsheets (.wq1, .wq2 and .wkq files). Search through these files as if they were plain text files, even if you don't have the original software that created those files.

The Search feature is very useful for searching through archived files. Suppose you remember writing a letter or email about something, but you do not remember to who and when, simply type in a relevant keyword in PowerGREP and search through all your archived correspondence. If you are a programmer, you can quickly search through all your source code, or your development tool's library source code. You could type in a function name to see where and how it is used, which is very useful when studying new library functions, or when you plan to modify one of your own library functions. Tracking particular events in huge numbers of log files is easy. Type in a relevant keyword or regular expression (see below) matching the event, and PowerGREP will give you a list of log file lines where that event occurred.

Using regular expressions will unleash the true power of PowerGREP. Regular expressions allow you to search for information even if you do not know exactly what you are looking for. If you are looking for an email address, construct a regular expression matching any email address, and PowerGREP will happily present you with all email addresses it can find in the files you had it search through. It is even easier: simply open the example PowerGREP Action file for finding email addresses that is included with PowerGREP, and let it run. When

you have the list, double-click the email addresses to inspect the context so see which is the one you were looking for. If you know something happened in October 2002, you could search using the regular expression 2002-10-[0-3]?[0-9]. That is, the text 2002-10-, followed by an optional digit between 0 and 3, followed by another digit. If you are unsure about the date format, just search using 2002-10-[0-3]?[0-9]| [0-3]?[0-9]/10/(20)?02|10/[0-3]?[0-9]/(20)?02. Looks a bit complicated, but building such a regular expression is quite straightforward once you have a little bit experience. It took me about 30 seconds to write the last one from scratch. While you can do many complex things with regular expressions, many classic searches are easy to do with regular expressions. Searching for any of a bunch of keywords, simply separate them with a pipe symbol: keyword1|keyword2|keyword3. Looking for a word starting with "cat"? Just use \b for the word boundary, and \w+ for one or more word characters (i.e. letters): \bcat\w+. Very easy, once you know how. PowerGREP's help file and printable manual will tell you all there is to know about regular expressions. It almost goes without saying that after carefully crafting a complex regular expression, you can easily save it into a PowerGREP library for instant reuse. Or, share libraries with colleagues and friends. PowerGREP's regular expression syntax is fully compatible with Perl, Java and .NET, including all flavor-specific extensions. Many other programming languages and tools use the same regular expression syntax. Learning regular expressions is a smart investment. They have many applications in addition to those offered by PowerGREP.

Powerful Text File Maintenance with Regular Expressions While searching and replacing pieces of text is useful, you can automate many tedious editing tasks by adding regular expressions to the mix. Let me present you with an example. Suppose you have a rather long list of pairs in the form of one=another and you want to swap them. You can do this easily with PowerGREP by searching with the regular expression (\w+)=(\w+) and

http://www.powergrep.com/replace.html

2006/12/18

Powerful Text File Maintenance with Search and Replace using Regular Expressions

Page 2 of 3

replacing with \2=\1. The regular expression will match a word, followed by an equals sign, followed by another word. The parenthesis capture the first word into the first "backreference", and the second word into the second "backreference". In the replacement text, we can reuse those with \1 and \2 respectively. So setting the replacement text to \2=\1 will swap the words. Do not worry if the above looks complex. The documentation that is included with PowerGREP contains a detailed introduction to regular expressions. With a bit of practice, you can create simple regular expressions like the above in a matter of minutes. And when you spend time creating a complex regular expression, you can save it into a PowerGREP action file or library for instant reuse later.

Unlimited Power and Flexibility While many Windows grep tools can search and replace with a single regular expression, PowerGREP offers unparalleled power and flexibility. Apply many changes at once by using a list of regular expressions. You can have the list processed sequentially, where each step works on the results of all previous steps, or concurrently, where each step is independent. There's no limit to the number of regular expressions you can use. You can easily perform complex editing and conversion tasks with PowerGREP's unique file sectioning and extra processing features. Instead of creating one complex regular expression that does it all, use several simple regular expressions that work together. Use file sectioning to process only certain parts of each file, such as only headings, only body text, only markup tags, only comments and strings in source code, etc. Use extra processing to modify each search match in any way you want using full regular expressions, not just simply move text around with backreferences.

Create PowerGREP Actions Instead of Writing a Log Analyzer If you are developing software that generates log files, or work with custom software that does, you can save a lot of time by creating a PowerGREP library. Share this library with customers or colleages that use the same software, instead of investing a lot of time in creating a log analyzer specific to that software. Start with creating regular expressions that match the various entries in the log files. Then use those regular expressions to create PowerGREP actions that calculate various interesting statistics or extract useful entries from your logs. Finally, put those actions into a PowerGREP library. This is a single file that you can easily email to others or make available for download. Anybody can then open that library in PowerGREP, pick an action from it, specify the location of their log files, and instantly get the specific information they want. They do not need to know anything about regular expressions or understand how PowerGREP works to do this.

Regular Expression Sequences Most grep tools can only search for a single regular expression. With PowerGREP you can use as many regular expressions or literal search terms as you want, with PowerGREP's unique regular expression sequence capabilities.

Buy & Download PowerGREP Now Only US$ 149 Windows 98, ME, NT4, 2000, XP and Vista. 100% satisfied or money back free trial download

In the screen shot, I'm performing two substitutions at once, replacing "classification" with "category", and "cat" with "dog". I've also restricted the search to comments and strings in Java and C++ source code files, using three simple regular expressions. One for single-line comments, one for multi-line comments, and one for strings. All this is very straightforward in PowerGREP, but impossible with any other grep tool.

Three Sequences

File Formats A PowerGREP action can consist of up to three sequences:

Press Resources Newsletter Version History Affiliates

The main search, search-and-replace or data collection action. Extra processing applied to the substitution text in a search-and-replace or data collection action. File sectioning to limit the search to specific parts of each file, or to split files into records or sections. No other Windows grep tool offers you such flexibility in combining multiple regular expressions. Suppose you want to convert image file references from local Windows folders to UNIX server directories. Trying to do this with a basic grep tool that can use

http://www.powergrep.com/sequence.html

2006/12/18

Regular Expression Sequences - Search and Replace with Multiple Regular Expressions Page 2 of 2

only a single regular expression would require a very complicated and incomprehensible regex. With PowerGREP it's much easier to use three simple regular expressions: one to limit the search to IMG tags, one to substitute SRC attributes in the IMG tags, and one to covert Windows back slashes to UNIX forward slashes in the SRC attribute paths.

Overlapping and Non-Overlapping Searches It's up to you what happens when executing the example in the screen shot on the string "The classification for cat is mammal." If you turn on non-overlapping search, "classification" is replaced with "category" and "cat" with "dog", resulting in "The category for dog is mammal." If you turn off non-overlapping search, replacements will cascade. While undesirable in some situations, the cascade enables you to perform some very powerful data conversions. In our simple example, the first substitution would result in "The category for cat is mammal. If we're not restricting the search to whole words, the second will result in "The dogegory for dog is mammal."

The key benefit of PowerGREP's file sectioning is that using it, you can keep your regular expressions or search queries simple. In the screen shot, you can see a search-and-replace to be executed on Java and C++ source code files. With PowerGREP's file sectioning feature, the search is restricted to comments and strings in Java and C++ source code files. This is done with a sequence of three simple regular expressions. One for single-line comments, one for multi-line comments, and one for strings. Achieving the same with a single regular expression in a basic grep tool is certainly possible, but far more complicated. With PowerGREP, you just need three off-the-shelf (or, off PowerGREP's library) regular expressions that you can reuse in many situations.

More Power to Reduce Complexity It may seem contradictory, but the most powerful Buy & Download PowerGREP Now Windows grep tool is also the easiest one to use, Only US$ 149 after a bit of practice. The reason is that you can Windows 98, ME, NT4, 2000, XP and Vista. execute many tasks in PowerGREP with several 100% satisfied or money back simple regular expressions, whereas a basic free trial download grep tool would require you to create one very complex regular expression to achieve the same result.

An example will make this clear. When searching through or modifying source code files, you'll often want to restrict the search to comments and/or strings, or search through comments and/or strings exclusively. E.g. if you discover you've been misspelling "referrer" as "referer" throughout your project, you'd probably want to fix the mistake in comments and strings, but leave the actual source code untouched. Modifying the source code might break ties to other modules, a hassle not worth correcting a spelling mistake. (As a bit of trivia: the Apache web server stores the referring URL in a variable HTTP_REFERER for exactly this reason.) PowerGREP makes this easy with its "file sectioning" feature. Simply use stock regular expressions for matching comments and strings to section the file. Then use a plain text search-and-replace to substitute "referer" with "referrer". Quick and easy. You'll find this particular example in PowerGREP's grep library. In many other situations, you'll be able to use common regular expressions you'll find in libraries with tools like RegexBuddy or on various web sites.

Examples Windows grep File Formats Press Resources

Select "search for sections" from the "file sectioning" list in PowerGREP. Set the section search type to "list of regular expressions". Add one regular expression to the list for each kind of string and comment the programming language you're working with supports. E.g. for C or Java, use //.* for single-line comments, (?s)/\*.*?\*/ for multi-line comments, and "[^"\\\r\n]*(?:\\.[^"\\\r\n]*)*" for strings. Set the action type to "search and replace". Enter "referer" as the search text, and "referrer" as the replacement. Done!

Using a Single Regex (Don't Try This at Home)

Affiliates How hard can it be to do this with a traditional grep tool that uses only a single regular expression? It turns out it is neigh impossible. The closest solution I found is to search for (//.*?)referer(.*)| ("[^"\\\r\n]*(?:\\.[^"\\\r\n]*)*)referer([^"\\\r\n]*(?:\\.[^"\\\r\n]*)*")| (?s:(/\*.*?)referer(.*?\*/)) and replace with \1\3\5referrer\2\4\6. Unfortunately, this behemoth only replaces the first occurrence of "referer" in each comment or string, while PowerGREP replaces them all at once. Don't make your life difficult by choosing a simple grep tool!

The Real Time Savings Since PowerGREP enables you to use stock patterns in many situations, you can save a lot of time by saving your PowerGREP actions into a library. E.g. if the next day you want to extract email addresses from comments and strings, you'd use the same file sectioning settings. Instead of doing the search and replace, you'd search for a regex matching an email address, using a standard regular expression from

a library, such as \b[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}\b. With another Windows grep tool, where you only have a single regex at your disposal, you could try: //.*?(\b[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}\b).*| "[^"\\\r\n]*(?:\\.[^"\\\r\n]*)*(\b[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}\b) [^"\\\r\n]*(?:\\.[^"\\\r\n]*)*"| (?s:/\*.*?(\b[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}\b).*?\*/). You won't find something like this in any library. Too complicated. Changing your mind is easy too. If you want to search through everything except comments or strings, or you want to search through either comments or strings only, you can use the same regular expression in PowerGREP. You just need to change a few options in the file sectioning. It only takes a few seconds. But if you had to use one of the behemoth patterns above, you'd have to rewrite it completely.

"The new file selector is fantastic - a huge improvement over almost anything else I've seen. I have often found it annoying when I have several directories spread out across the filesystem that I want included in one search. This generally required either complex file masks of multiple searches in the past. Now once I get to work on a given project, it's all right there and can be modified in no time."

The key benefit of using PowerGREP's built-in editor is that you can easily inspect the full context of each highlighted search match. Click the Next Match and Previous Match buttons to quickly navigate through all matches in the file. Match highlighting persists even when you edit the file. After previewing or executing a search-and-replace action, you can conveniently replace or revert individual matches. Simply click on the match, and then click the Replace or Revert button in the editor. To replace just a few of the search matches, preview the action and then replace individual matches. To replace most search matches, execute the action (which replaces all matches), and then revert those individual matches that you didn't want to replace.

Affiliates PowerGREP's method of replacing and reverting individual matches is far more intuitive than the way most Windows search-and-replace tools work. The typical Windows grep tool forces you to answer a Yes/No question popping up for each search match, in the order that matches are found. PowerGREP gives you the opportunity to replace and revert matches in any order, whenever you want, with full editing access to the file.
