xsl editor

Hello,
I have picked up a very very large xsl file that transforms huge xml files into advertising ads.

I am learning xsl and I am finding the xsl file quite large and klugy to handle. My problem is I am trying to find of what eg: when:test lines up with the /when:test and so on.

So my question is, are there any editors out there that may assist and show the opening tag and closing tag?
