Re: Evaluating last 3 or 4 characters of URL?

XPath error Invalid expression
substring({@url}, -5, 5)='.html'

Look again carefully. The period before the file extension isn't being counted in the length of the substring you are testing. You will have to change "substring({@url}, -4, 4)" to substring({@url}, -5, 5)" if you want to test it against ".html".

Subject:   Evaluating last 3 or 4 characters of URL?

I am trying to evaluate the last 3 or 4 characters of a URL
so that I can add javascript in the href attribute.

It is not liking the {@url}.  Is this not just the string value
of the url attribute? Help on the syntax appreciated.
