Regex pattern VB.NET

Question

How can i extract this from a website?

I know how to do web requests I just cant get my head around the regex pattern.

I want to download a file using a link and that link is in this html code.

<a href="#" onclick="downloadStart();window.location='http://url.co.uk/download/2690'"><button type="submit" class="css3button" value="download">Download</button></a>

This is the url I want http://url.co.uk/download/2690

Thank you any help is very grateful.

For parsing html it would probably be easier to use an html parser than regex. Html is not regular. — multivac, Oct 03 '15 at 16:48
@multivac but even then I dont know where to start. I dont wanna be spoon fed but I am no good with regex patterns. Tried many times. — Sam Sheppard, Oct 03 '15 at 16:49
If it always has a double-quote at the end then all you need to do is get the substring up to the indexof the double-quote. — Andrew Morton, Oct 03 '15 at 16:52

You can try this regex:

http://url.co.uk/download/[^'"\s]+?(?=['"\s])

This will extract all urls from the page which are the fomat: http://url.co.uk/download/*

Beware that this won't be limited to only anchor tags though.
