That solution confuses me (Query at the end ...)

The following appears to work:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="";

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

    <xsl:template match="/">
      <xsl:value-of select="string-length(child::*[1])"/>




That solution confuses me - I would have expected descendants to work,
rather than child::*[1].
      <xsl:value-of select="string-length(descendants)"/>

Can somebody comment on what is happening in this line?
