Hey Rick,
Perhaps another way to accomplish your goal is simply a test on whether
such a text node child exists:
exists(child::text()[matches(.,'\S')])
returns true when a child text node has any non-whitespace content.
Cheers, Wendell

Hi All,
I am trying to flatten a messy XHTML file by unwrapping any elements that
don’t have non-whitespace text nodes. I am trying to return a single string
from all of the text nodes in an element and see if its normalized value is
an empty string. Here is my sample input:
<?xml version="1.0" encoding="UTF-8"?>
<root>This has <b>some </b>text.</root>
Here is my stylesheet:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:math="http://www.w3.org/2005/xpath-functions/math";
xmlns:rq="http://www.frameexpert.com/functions";
exclude-result-prefixes="xs math rq"
version="3.0" expand-text="yes">
<xsl:output indent="yes"/>
<xsl:strip-space elements="td"/>
<xsl:template match="/root">
<xsl:message>{text()}</xsl:message>
<xsl:message>{count(text())}</xsl:message>
<xsl:message>{count(rq:getStringFromText(text()))}</xsl:message>
<xsl:apply-templates/>
</xsl:template>
<xsl:function name="rq:getStringFromText" as="xs:string*">
<xsl:param name="text-nodes"/>
<xsl:for-each select="$text-nodes">
<xsl:value-of select="normalize-space(.)"/>
</xsl:for-each>
</xsl:function>
</xsl:stylesheet>
I expected that this line
<xsl:message>{count(rq:getStringFromText(text()))}</xsl:message>
would return 1, but instead I get 2. Perhaps I need recursion in my
function. Thank you in advance.
Rick
