<PMT NM="THEME" DN="THEME" IR="0" T="0">
    <PV V="fast" L="" H="" C="4"/>
</PMT>
<PMT NM="INGREDIENTS" DN="INGREDIENTS" IR="0" T="0">
    <PV V="chicken" L="" H="" C="5"/>
    <PV V="tomato" L="" H="" C="12"/>
</PMT>
</PARM>

 <facet-group>
  <name>THEME</name>
  <facets type="array">
    <facet>
      <name>fast</name>

    </facet>
  </facets>
 </facet-group>
 <facet-group>

This is the @LarsH in other words:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:strip-space elements="*"/>
    <xsl:output indent="yes"/>

    <xsl:template match="PARM">
        <facet-groups type="array">
            <xsl:apply-templates select="PMT"/>
        </facet-groups>
    </xsl:template>

    <xsl:template match="PMT">
        <facet-group>
            <name><xsl:value-of select="@NM"/></name>
            <facets type="array">
                <xsl:apply-templates select="PV"/>
            </facets>
        </facet-group>
    </xsl:template>

    <xsl:template match="PV">
        <facet>
            <name><xsl:value-of select="@V"/></name>
            <count><xsl:value-of select="@C"/></count>
        </facet>
    </xsl:template>

</xsl:stylesheet>

As @Keoki said, you should show more of what you've done, before it would be appropriate to give you a whole solution. But to get started, you would create

  • a template matching "PARM", that outputs a facet-groups element and within that, applies templates to children

  • a template matching "PMT", that outputs a facet-group element, with children <name> and <facets>, and within the latter, applies templates to children

  • a template matching "PV", that outputs a facet element, with children <name> and <count>

Hopefully that will give you a good start.
