I need to isolate a string of text that at times may vary in length. The string in question is: IN.Tags.Share.handleCount({"count":2,"fCnt":"2","fCntPlusOne":"3","url":"http:\/\/relevance.com\/blog\/blog-editing-tip-use-adverbs-carfeully\/"});

I'm interested in isolating the number highlighted in red; however, the function (or combo of functions) must be able to gather numbers that may be multiple digits in length.

Super thanks in advance,

Phil
