[xsl] Re: Siblings to child - Hierarchy

Use the following transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

 <xsl:output omit-xml-declaration="yes" indent="yes"/>

  <xsl:template match="rowset">
    <site>
      <xsl:apply-templates select="row[site_parent = 0]"/>
    </site>
  </xsl:template>

  <xsl:template match="row">
    <xsl:copy-of select="site_id | site_name"/>
    <xsl:variable name="vChildren"
        select="../row[site_parent = current()/site_id]"/>
    <xsl:if test="$vChildren">
      <site>
        <xsl:apply-templates select="$vChildren"/>
      </site>
    </xsl:if>
  </xsl:template>

</xsl:stylesheet>

When applied against your source.xml:

<page>
  <rowset>
    <row>
      <site_id>1</site_id>
      <site_name>Test Parent1</site_name>
      <site_parent>0</site_parent>
      <level>1</level>
      <path>/0</path>
    </row>
    <row>
      <site_id>2</site_id>
      <site_name>Test Child1 of Test Parent1</site_name>
      <site_parent>1</site_parent>
      <level>2</level>
      <path>/0/1</path>
    </row>
    <row>
      <site_id>4</site_id>
      <site_name>Test Child1 of Test Child1</site_name>
      <site_parent>2</site_parent>
      <level>3</level>
      <path>/0/1/2</path>
    </row>
    <row>
      <site_id>3</site_id>
      <site_name>Test Parent2</site_name>
      <site_parent>0</site_parent>
      <level>1</level>
      <path>/0</path>
    </row>
  </rowset>
</page>

the wanted result is produced:

<site>
  <site_id>1</site_id>
  <site_name>Test Parent1</site_name>
  <site>
    <site_id>2</site_id>
    <site_name>Test Child1 of Test Parent1</site_name>
    <site>
      <site_id>4</site_id>
      <site_name>Test Child1 of Test Child1</site_name>
    </site>
  </site>
  <site_id>3</site_id>
  <site_name>Test Parent2</site_name>
</site>
