Extract value out of another value (possibly using RegEx)

What I am looking for is a way to extract the URL out of an href attribute. I care about all parameters EXCEPT the sessionToken parameters.

So this…

<A class=ContentURL href="javascript:void(window.open('../content/ModuleList.aspx?PageID=module&amp;sessionToken=[sessionToken]','report','scrollbars=y开发者_JS百科es,resizable=yes,width=640,height=500'))">Manage Applications</A>

Should give me this…

../content/ModuleList.aspx?PageID=module

And this…

<A class=ContentURL href="javascript:void(window.open('../content/ModuleList.aspx?PageID=module&amp;sessionToken=[sessionToken]&amp;Token=DateTime','report','scrollbars=yes,resizable=yes,width=640,height=500'))">Manage Applications</A>

Should give me this…

../content/ModuleList.aspx?PageID=module&Token=DateTime

I have to imagine there is a way to do this using RegEx and I was hoping someone could show me how.

If all of your links have the same format you specified, then pattern for extracting URLs is simple:

href="javascript:void\(window\.open\('(.+?)'.*?"

URL will be captured by the first group: (.+?).

Now having extracted URLs, you can do anything you want with them. If you want to remove sessionToken parameter without breaking GET string (by accidently removing ? or & character), you should replace (\??)sessionToken=[^&]*&? with 1st capturing group (a ? if sessionToken is a first parameter and an empty string if it's not). You might also want to remove trailing & if sessionToken is a last parameter, but that's not necessarily.
