Regex to retrieve string

Question

I wish to match

&amp;v=

and before

">

is there a regex match i could use

Example:

<a accesskey="1" href="/watch?gl=GB&amp;client=mv-google&amp;hl=en-GB&amp;v=ubNF9QNEQLA">Test Your Awareness : Whodunnit?</a>

i only need the ubNF9QNEQLA

Thanks

You want to *split* or to *match*? Splitting suggests you want to break the string into pieces based on some delimiter, but you gave two. Or do you just want to get the content that's between those two tokens? — VoteyDisciple, Oct 17 '10 at 14:42
Since there is no built-in full regex engine in Objective C (for reference: http://stackoverflow.com/questions/422138/regular-expressions-in-an-objective-c-cocoa-application), could you kindly indicate which library/function you're using to do the match with? The answers thus far have presumed PCREs, but I am guessing you're using the built-in POSIX regexes which are significantly less powerful. — Conspicuous Compiler, Oct 17 '10 at 15:36

I have no idea why it does not work for you. It works for me, though. – Alan Haggai Alavi Oct 17 '10 at 15:30

 /&v=(.*?)">/

The question mark tells the wild char matching to be lazy so it will stop at the first "> rather than at the last one.

@user, can you post a sample string? – Motti Oct 17 '10 at 15:03
as you can see i changed it from &v= to &v= seeing as the code function did not work the first time – user393273 Oct 17 '10 at 15:06
@user and did you modify the regex accordingly? – Motti Oct 17 '10 at 15:17
Yes i believe so, also i posted an example at the top in an edit – user393273 Oct 17 '10 at 15:18
