which didn't seem to work.  Unfortunately I'm not a moderator for this

Good.  This means it really is a whitespace issue.

Try setting the Transformer to Xalan instead.  XMLUnit uses the
following (trivial, I think) stylesheet to strip whitespace when you
enable ignoreWhitespace.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
  <xsl:output method="xml" version="1.0" indent="no"/>
  <xsl:strip-space elements="*"/>
  <xsl:template match="/"><xsl:copy-of select="."/></xsl:template>
</xsl:stylesheet>

No idea why Saxon should choke on it.
