// add stuff to an xml document in php4
$doc = domxml_open_mem($xml);
$root = $doc->document_element();
$inner = $doc->create_element('inner');
$root = $root->append_child($inner);

// add stuff to an xml document in php5
$doc = new DomDocument('1.0', 'UTF-8');
$doc->loadXML($xml);
$root = $doc->getelementsByTagName('resultset')->item(0);
$inner = $doc->createElement('inner');
$root = $root->appendChild($inner);

XHTML does not allow to have an empty list, <ul></ul>. Therefore we need to test first if there are any nodes we want to put in that list. The code to do this looks like:

<xsl:for-each select="//resultset/entity">
  <div class="mainitem">
  <div class="maintitle"><xsl:value-of select="title"/></div>
  <div class="maincontent">
    <xsl:if test="count(items/item) &gt; 0">
      <ul>
        <xsl:for-each select="items/item">
        <li><a href="{link}"><xsl:value-of select="title"/></a></li>
        </xsl:for-each>
      </ul>
    </xsl:if>
  </div>
  </div>
</xsl:for-each>
