I have a regex like this in my json file
"body": {
"content": "<div class=(?:\"|')content(?:\"|') [^>](.*?)</div>\\;content:\\1",
}
As of now its only match first content div.
Can someone tell me how to make it greedy?

what html are you trying to match? – user428517 Aug 08 '13 at 19:36

Do you want it to match all content until the last ? – seanmk Aug 08 '13 at 19:36

1If you want it to match up to to `` that matches with the openining `` you're going to have to use something more powerful than regex. Regex can't count. If you're using Javascript in a browser you can just use the native DOM.– Paul Aug 08 '13 at 19:39

@seanmk yes. Also I want to match every div that has content class using the global (g) modifier – PrivateUser Aug 08 '13 at 19:44

.*? is a non-greedy (or lazy) quantifier. To make it greedy just remove the ?:
"body": {
"content": "<div class=(?:\"|')content(?:\"|') [^>](.*)</div>\\;content:\\1",
}
Of course, as has been said many times before, you shouldn't use regular expressions to parse html.
To use the global mode, simply specify it when you're creating your RegExp, either like this:
"body": {
"content": /<div class=(?:"|')content(?:"|') [^>](.*)</div>\\;content:\\1/g,
}
Or like this:
"body": {
"content": new RegExp("<div class=(?:\"|')content(?:\"|') [^>](.*)</div>\\;content:\\1", "g"),
}
Of course at this point, it's no longer pure Json. Really, I'd recommend specifying the flags elsewhere. For example, in whatever code you have which actually does the html processing.

Ok got it. Now can you tell me how to match every content class using the global (g) modifier ? – PrivateUser Aug 08 '13 at 19:40
