today i break my head with a regex. I can't extract a part of text. My text is like this:

<!--TEXT[title]-->
sometext 1
<!--END-->
<!--TEXT[title]-->
sometext 2
<!--END-->

I want get this in a array 

["title]-->sometext1"
,"title]-->sometext2"]

i have this regex code mytext.match(/<!--TEXT[([.|\w|\r|\n]+)<!--END-->/m);

    Is this text inside of some HTML? If so, don't parse HTML with a regex: http://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454 Instead, parse the DOM. –  Oct 20 '11 at 14:37

Assuming you need a regular expression the following should work:

<\!--TEXT\[([^\]]*)\]-->\s*\n(.*)(?!<\!--END-->)

If this text is in a DOM it would be much better to parse the DOM however.

Explanation:

<\!--TEXT\[ // Match the start.
([^\]]*) // Match (in group 1), everything up until the next ']'
\]-->\s*\n // Match to the end of this line.
(.*) // Match anything (in group 2).
(?!<\!--END-->) // Stop before the end tag is next. (This will mean you get everything up to, but not including the previous line break).

    Of course this will fail with nested comments, but this is something the OP should know... – FailedDev Oct 20 '11 at 14:49
  • Yes, if you're dealing with nested comments you want a lexer or a DOM. On the other hand in this particular case it doesn't look like they would be nested (without there being some error). – Vala Oct 20 '11 at 14:56
