I have a hash which contains a regular expression: the number of matches to be captured in it and variables and their position of match. For example: my %hash = ( reg_ex => 'Variable1:\s+(.*?)\s+\n\s+Variable2:\s+(.*?)\s+\n', count => 2, Variable1 => 1, Variable2 => 2, ); I am going to use this regex in some other par...

As stated in the title, is there a way, using regular expressions, to match a text pattern for text that appears outside of quotes. Ideally, given the following examples, I would want to be able to match the comma that is outside of the quotes, but not the one in the quotes. This is some text, followed by "text, in quotes!" or ...

EDIT: Can anyone help me out with a regular expression for a string such as this?: [Header 1], [Head,er 2], Header 3 so that I can split this into chunks like: [Header 1] [Head,er 2] Header 3 I have gotten as far as this: (?<=,|^).*?(?=,|$) Which will give me: [Header 1] [Head ,er 2] Header 3 Thanks!! ...
I'm trying to write a regular expression pattern (in python) for reformatting these template engine files. Basically the scheme looks like this: [$$price$$] { <h3 class="price"> $12.99 </h3> } I'm trying to make it remove any extra tabs\spaces\new lines so it should look like this: [$$price$$]{<h3 class="price">$12.99</h...
Hi guys, I have an API call that essentially returns the HTML of a hosted wiki application page. I'm then doing some substr, str_replace and preg_replace kung-fu to format it as per my sites style guides. I do one set of calls to format my left nav (changing a link to pageX to my wikiParse?page=pageX type of thing). I can safely do thi...

I've always been interested in writing web software like forums or blogs, things which take a limited markup to rewrite into HTML. But lately, I've noticed more and more that for PHP, try googling "PHP BBCode parser -PEAR" and test a few out, you either get an inefficient mess, or you get poor code with XSS holes here and there. Taking...
What's the easiest way to parse a string and extract a number and a letter? I have string that can be in the following format (number|letter or letter|number), i.e "10A", "B5", "C10", "1G", etc. I need to extract the 2 parts, i.e. "10A" -> "10" and "A".

I dont fully understand the syntax of regex's yet sorry! Thanks, Ash ...
I am currently using split() to scan through a file where each line has number of strings delimited by '~'. I read somewhere that Scanner could do a better job with a long file, performance-wise, so I thought about checking it out. My question is: Would I have to create two instances of Scanner? That is, one to read a line and another ...
I am using preg_replace() for some string replacement. $str = "<aa>Let's find the stuff qwe in between <id>12345</id> these two previous brackets</h>"; $do = preg_match("/qwe(.*)12345/", $str, $matches); which is working just fine and gives the following result $match[0]=qwe in between 12345 $match[1]=in between but I am using s...
There are times when I want to convert user input into its literal value in a regular expression. I.e. if the user enters C:\Win\Bin\File.txt the regular expression would be something like C:\\Win\\Bin\File.txt since certain character combinations have to be escaped. Does anyone know of either a tried and true piece of code that does t...
I need to write a Perl script to read in a file, and delete anything inside < >, even if they're on different lines. That is, if the input is: Hello, world. I <enjoy eating bagels. They are quite tasty. I prefer when I ate a bagel to when I >ate a sandwich. <I also like >bananas. I want the output to be: Hello, world. I ate a sandwic...
I have an XML file containing one (or more) key/value pairs. For each of these pairs I want to extract the value which is a two-byte hex value. So the XML contains this snippet: <key>LibID</key><val>A67A</val> Which I can match using the following expression, with the ID in parenthesis. Match match = Regex.Match(content, @"<key>LibI...
This question is similar to "How to concisely cascade through multiple regex statements in Python" except instead of matching one regular expression and doing something I need to make sure I do not match a bunch of regular expressions, and if no matches are found (aka I have valid data) then do something. I have found one way to do it bu...
I noticed that it is very slow for a Regex to finish a XML file with 3000 lines [1]: \(<Annotation\(\s*\w\+="[^"]\{-}"\s\{-}\)*>\)\@<=\(\(<\/Annotation\)\@!\_.\)\{-}"MATCH\_.\{-}\(<\/Annotation>\)\@= I always thought that Regexes are efficient. Why does it take so long to finish the Regex? [1] http://stackoverflow.com/questions/7363...
I have had problems in Regexes to divide a code up into functional components. They can break or it can take a long time for them to finish. The experience raises a question: "When should I use a parser?" ...
