Almost any XML will do for the first param. e.g.:

select xslt_process( query_to_xml('select x from generate_series(1,5) as 
x',true,false,'')::text,
$$<xsl:stylesheet version="1.0"
               xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" />
<xsl:template match="*">
  <xsl:copy>
     <xsl:copy-of select="@*" />
     <xsl:apply-templates />
  </xsl:copy>
</xsl:template>
<xsl:template match="comment()|processing-instruction()">
  <xsl:copy />
</xsl:template>
</xsl:stylesheet>
$$::text);
