Re: [xsl] Value-of, copy-of

[Wendell Piez <wapiez at mulberrytech dot com>]

Mike,

Ah, the reason this is tricky is ... it's tricky.

If your context node is the C1001 (that is, you're in a template matching 
the C1001), then you want all children except the C1007 and C1011 children.

That would be:

<xsl:copy-of select="node()[not(self::C1007) and not(self::C1011)]"/>

This translates as "copy all child nodes that are not themselves C1001 
nodes and not C1011 nodes, either".

This actually works out to be the same as

<xsl:copy-of select="node()[not(self::C1007|self::C1011)]"/>

The reason for this is that the expression (self::C1007|self::C1011) tests 
as true for any C1007 or C1011 node, but false for any other. That's 
because those two are the only kinds of nodes from which the union of these 
two XPath expressions (which both traverse the self:: axis), returns a 
node-set with any node in it.

But that may be more than you wanted to know. :-)

Cheers,
Wendell
