Re: [xsl] test on string-length of text() for element with node

[Andrew Welch <andrew.j.welch@xxxxxxxxx>]

Ah sorry it's because in XSLT 1.0 'first item semantics' kick in when
you supply a sequence of more than 1 item to a function that expects
only one... so doing /text() returns multiple nodes and then all but
the first are silently dropped.

I haven't written any xslt 1.0 for a long time, but I think you would
need to store all the text node in a variable, then get the string
length of that:

<xsl:variable name="text">
  <xsl:for-each select="/path/to/maritalstatus/text()">
    <xsl:value-of select="."/>
  </xsl:for-each>
</xsl:variable>

<xsl:value-of select="string-length($text)"/>

If you want to ignore whitespace only nodes, then use xsl:strip-space
on the <maritalstatus> element or do text()[normalize-space(.)]
