preceding-sibling

I have a probkem using preceding-sibling

Here is my xml and xslt. I am trying to output the Age and previous age. This is just a contrived example to illustrate an example.

Any ideas?

Thanks

Dave

Thanks man, your a star!

How do you learn all this stuff, I find it very unintuitive and books I have tried reading seem difficult too.

Thanks

O'Reillys XSLT book and 5 years experience. The only way comes from doing it, and it's much easier if you can do it in a decent editor like XMLSPy that gives you XPath functionality in an xml doc so you can test your expressions.

Cheers for the points and the grade.

Ok thanks

I'm using Xml Spy so at least I'm on the right path...
