Ok, I guess that could be a gotcha... in which case, just do: match="@href[exists(/html)]" It's funny how this has come up - I've just left a place where they had two types of XML - one with <page> for the root element, the other with <response>, and throughout the code, all over the place, they had choose/when's with [ancestor::page] and [ancestor::response]... so I changed it all to use global variables instead. The gotcha didn't occur to me at the time.... I think they will be alright though :) -- Andrew Welch http://andrewjwelch.com Kernow: http://kernowforsaxon.sf.net/
