Hello all,
I have a sequence of nodes stored in a variable, and I am attempting to filter
it using an XPath expression that includes the "except" operator. However,
it's not working like I expect it to.
For a node sequence called $normalized_data:
<data id="1">
<info action="delete" />
<info action="insert" />
<stuff />
</data>
<data id="2">
<info action="insert" />
<stuff />
</data>
<data id="3">
<stuff />
</data>
I am attempting to filter it using this logic:
<olddata>
<xsl:sequence select="$normalized_data[not(info/@action='delete')] except
$normalized_data[info/@action='insert' or info/@action='modify']" />
</olddata>
I expect the returned sequence to include all of the nodes in $normalized_data
that match the first condition and don't match the second condition (node 3).
What I am actually getting is all of the nodes in $normalized data. Is there
something about the "except" operator that I'm not understanding?
Thanks,
-James
