Regex: HTML, contents

I'm having a little issue with getting a value of field in HTML using regex.

There is a input tag in the html which is unique and here it is below.

<input type="hidden" name="t" value="I-WANT-TO-GET-THIS"/>

I would like to know, using REGEX only, how to get "I-WANT-TO-GET-THIS" (without quotes).

Thank-you very much for your time Paul

RegExp:

<input [^>]*?value="([^"]*)"

See an working example here: http://www.rubular.com/r/mG8AYSd5A1

Pattern:

<input [^>]*? value="(.*)"

How are you doing this? The best idea is to use a HTML parser. Regex with HTML has its own issues, see the link: RegEx match open tags except XHTML self-contained tags
