Hi,
FWIW, a small performance hint:
My Friends,
Thank you for the many suggestions! I have tried them all and my
issue, as suggested by Jean-Francois appears to be related to the
fact that my xml tag "send-fax" is not a direct child of the node I
am processing. Instead, it a "remote descendant". Therefore, I
used the following code:
<xsl:when test="count(//send-fax = 0">
Seems better to use:
<xsl:when test="not(//send-fax)">
Why?
The node-set is implicitly converted to a boolean, which the
processor (if intelligent enough) can evaluate as "true" as soon as
the first such node is encountered. The expression "count(//send-
fax)", OTOH, is more likely to trigger a complete tree-traversal
starting at the context node. IIC, using a boolean would only mean a
complete traversal iff the node-set is also empty (= false)
Cheers
Andreas
