Regex match an attribute value

What would the regular expression be to return 'details.jsp' (without quotes!) from this original tag. I can quite easily match all of value="details.jsp" but am having trouble just matching the contents within the attribute.

<s:include value="details.jsp" />

Any help greatly appreciated!

Thanks

Lawrence

/value=["']([^'"]+)/ would place "details.jsp" in the first capture group.

Edit:

In response to ircmaxell's comment, if you really need it, the following expression is more flexible:

/value=(['"])(.+)\1/

It will match things like <s:include value="something['else']">, but just note that the value will be placed in the second capture group.

But as mentioned before, regex is not what you want to use for parsing XML (unless it's a really simple case), so don't invest too much time into complex regexes when you should be using a parser.
