You could do it this way:
../node[not(text()) and preceding-sibling::node[@id][1][@id='1']]
where '1'
is the id of the current node (generate the expression dynamically).
The expression says:
- from the current context go to the parent
- select those child nodes that
- have no text and
- from all “preceding sibling nodes that have an id” the first one must have an id of 1
If you are in XSLT you can select from the following-sibling axis because you can use the current()
function:
<!-- the for-each is merely to switch the current node -->
<xsl:for-each select="node[@id='1']">
<xsl:copy-of select="
following-sibling::node[
not(text()) and
generate-id(preceding-sibling::node[@id][1])
=
generate-id(current())
]
" />
</xsl:for-each>
or simpler (and more efficient) with a key:
<xsl:key
name="kNode"
match="node[not(text())]"
use="generate-id(preceding-sibling::node[@id][1])"
/>
<xsl:copy-of select="key('kNode', generate-id(node[@id='1']))" />
