Re: [xsl] Matching only text nodes with certain (complicated) properties

Actually Dimitre, as long as this is TEI as the OP stated, the pb will never be an ancestor -- it'll always be on preceding axis. (As the OP noted in passing, it's a milestone -- always empty. :-)

Cheers,

As the OP stated in his opening message,

"As far as I understand it, the main problem is that the expression I
have to construct for matching can't rely simply on the preceding:: or
ancestor:: axes since the <pb/> can really appear anywhere in the
tree."

The following XSLT 1.0 transformation has a template that correctly
matches (only) the required text nodes:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:strip-space elements="*"/>

<xsl:template match="text()"/>

<xsl:template match=
"text()
[count(preceding::text()[1]/preceding::node()
| preceding::text()[1]/ancestor::node()
)
&lt;
count((preceding::pb[1] | ancestor::pb[1])[last()]/preceding::node()
|
(preceding::pb[1] | ancestor::pb[1])[last()]/ancestor::node()
)
]
