<!-- We need to remove any extraneous final spaces. -->
<!-- set context node to language-desc -->
<xsl:for-each select="$language-desc">
<!-- find last text node in descendants -->
<xsl:variable name="last-text-node" select="(.//text())[last()]"/>
<xsl:choose>
<xsl:when test="ends-with($last-text-node, ' ')">
<xsl:apply-templates mode="strip-final-space" select=".">
<xsl:with-param name="last-text-node"
select="$last-text-node"/>
</xsl:apply-templates>
</xsl:when>
<xsl:otherwise><xsl:sequence select="."/></xsl:otherwise>
</xsl:choose>
</xsl:for-each>
...
<!-- copy the context node tree, removing final space from the node
that is passed as a parameter. -->
<xsl:template mode="strip-final-space" match="@*|node()">
<xsl:param name="last-text-node" />
<xsl:choose>
<xsl:when test=". is $last-text-node"><xsl:value-of
select="substring(., 1, string-length(.) - 1)"/></xsl:when>
<xsl:otherwise>
<xsl:copy>
<xsl:apply-templates mode="strip-final-space"
select="@*|node()">
<xsl:with-param name="last-text-node"
select="$last-text-node"/>
</xsl:apply-templates>
</xsl:copy>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
I think this would do the same job:
<xsl:template match="text()">
<xsl:value-of select="if (. is
/path/to/lanuguage-desc/descendant::text()[last()][ends-with(., ' ')])
then
substring(., 1, string-length(.) - 1) else ."/>
</xsl:template>
