RE: [xsl] Different Colors for Alternating Rows

Kevin,

This time I didn't get the error and the performance was excellent (only
about 6 seconds), BUT every row came out with the oddStyle. Any clue
what is wrong?

Thanks,
Rechell

The EXSLT node-set() function is implemented in later versions of Xalan
but I 
guess you have something older. There is an equivilent function in older

versions called nodeset() which is under a different namespace. I have 
changed the stylesheet to use this. 

There are three changes, if you search on 'xalan' you will find each
one.
