Start with a named template and pull in the files or URIs with the Saxon
specific argument to the "collection" or "uri-collection" function:

<xsl:template name="xsl:initial-template">
   <xsl:value-of select="uri-collection('?select=*.xhtml') ! . || ' : '
|| doc-available(.)" separator="&#10;"/>
</xsl:template>

In theory I think that should check with doc-available if the file is
well-formed or not. Haven't tested however.
