Python RegEx: Extract link
===

I have this like:

    javascript:ColdFusion.Window.show('theformats');ColdFusion.navigate('exportformats.cfm?id=1900067&expformat=bibtex','theformats');

Let's split this into 2 parts:

1) 'exportformats.cfm?id=1900067&expformat=bibtex'
2) all the rest, left and right of it

What the BEST way in Python to get 1) given that 2) never changes?

So far, I have tried "finding" [ColdFusion.navigate('] in the string and slicing from there until [','] but I would really like to learn how to concoct the very best RegEx for it and do so in Python, please.
