I’m trying to better my understanding of “current node” behavior in
XSLT, and I have a couple questions.
1. Which stylesheet elements select the current node “.”?
The dot is used or usable in any XPath expression
(https://www.w3.org/TR/xpath-31/#dt-dynamic-context) so I would suggest
to rather look at XPath to understand the context item or context node
as otherwise stuff like
/items/item[cat[. = /categories/cat]]
will not be understood.
As a novice, I get confused remembering when the current node
does/doesn’t change. There’s also this, which I’m trying to grasp:
https://www.w3.org/TR/xslt-30/#func-current
What’s a good mental model for remembering this?
2. Inside an <xsl:template> block, is there a function that returns the
current **template-matched** node?
That is what the
current()
function does, I am currently not sure why you first cite it and then
seem to ask for another function doing the job of the current() function.
No Christopher was correct, there is no function that does what he asks,
and you need to use a variable.
current() is the node at the beginning of the xpath not the surrounding
template.
Given
<xsl:template match="wibble">
<xsl:for-each select=".//zzz">
<xsl:value-of select=" something with current()"/>
then current() is the zzz node, and wibble is not accessible unless you
saved it in a variable before the for-each.
