Hi everyone, and happy new year's!
Let's say I have a variable that contains a set of nodes:
<xsl:variable name="nodes" select="//(foo|bar|baz)"/>
In XPath 3.0, I can apply a template directly to this node-set
variable (very cool!):
<xsl:template match="$nodes">
However, what's the best way to use this node-set variable as a
predicate filter? For example, let's say I wanted to select every
preceding sibling node directly before each node in the variable:
<xsl:template match="preceding-sibling::node()[1][. intersect $nodes]">
The "interesect" operator works, but it's not intuitive. Is there a
simple Boolean operator that indicates whether a given node exists in
a set of nodes?
Or you can use
[generate-id() = $nodes!generate-id()]
as the predicate.
