Re: accessing multiple xml documents from within one

I have a solution now for accessing both trees, I have to step through
the reportDef using xsl:for-each. But now I have the next problem:

In $fieldname there is the desired tag, eg "title". Can I get the
title element of my current book node without looping through the
whole node and comparing with name(.)=$fieldname? The given sample is
a simplification, the real book node in my application has maybe 100
elements and with maybe 1000 books this would be a little bit too time
consuming.

any ideas?
