I would like to extend this so that it can handle an element
consisting of text lines with some embedded markup (there won't be
much, but there will be some). For example, taking:
<textlines>this is line <seq>1</seq>
this is <var>line</var> 2
this <emph>is</emph> line 3</textlines>
and producing
<textlines>
<line>this is line <seq>1</seq></line>
<line>this is <var>line</var> 2</line>
<line>this <emph>is</emph> line 3</line>
</textlines>
That part could be done with
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
exclude-result-prefixes="#all"
version="3.0">
<xsl:mode on-no-match="shallow-copy"/>
<xsl:mode name="insert-markers" on-no-match="shallow-copy"/>
<xsl:template match="textlines">
<xsl:copy>
<xsl:variable name="transformed-textlines">
<xsl:apply-templates mode="insert-markers"/>
</xsl:variable>
<xsl:for-each-group select="$transformed-textlines/node()"
group-ending-with="lb">
<line>
<xsl:apply-templates select="current-group()"/>
</line>
</xsl:for-each-group>
</xsl:copy>
</xsl:template>
<xsl:template mode="insert-markers" match="text()">
<xsl:analyze-string select="." regex="\n+">
<xsl:matching-substring>
<lb/>
</xsl:matching-substring>
<xsl:non-matching-substring>
<xsl:value-of select="."/>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:template>
<xsl:template match="lb"/>
</xsl:stylesheet>
