RE: Flattening a XML tree

Hi Farroq,

Try this XSL:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="no" indent="yes"/>

<xsl:template match="/Tree">
  <Tree>
    <xsl:for-each select="//TreeNode">
    <xsl:sort select="@id" data-type="number"/>
	<xsl:element name="TreeNode">
	  <xsl:attribute name="id">
          <xsl:value-of select="@id"/>
        </xsl:attribute>
	  <xsl:attribute name="weight">
          <xsl:value-of select="@weight"/>
        </xsl:attribute>
	</xsl:element>
    </xsl:for-each>
  </Tree>
</xsl:template>

</xsl:stylesheet>

It will produce the following XML (don't know if this was exactly what you
wanted):

<?xml version="1.0" encoding="UTF-16"?>
<Tree>
	<TreeNode id="1" weight="5"/>
	<TreeNode id="2" weight="3"/>
	<TreeNode id="3" weight="4"/>
	<TreeNode id="4" weight="2"/>
	<TreeNode id="5" weight="2"/>
	<TreeNode id="6" weight="2"/>
	<TreeNode id="7" weight="2"/>
	<TreeNode id="8" weight="2"/>
	<TreeNode id="9" weight="3"/>
	<TreeNode id="10" weight="2"/>
	<TreeNode id="11" weight="2"/>
	<TreeNode id="12" weight="2"/>
</Tree>

Cheers,
Frank.

Subject:  Flattening a XML tree


Hi,

I have an input tree that looks like this

<?xml version="1.0"?>
<Tree>
 <TreeNode id="1" weight="5">
  <TreeNode id="2" weight="3">
   <TreeNode id="6" weight="2"/>
   <TreeNode id="7" weight="2"/>
   <TreeNode id="8" weight="2"/>
  </TreeNode>
  <TreeNode id="3" weight="4">
   <TreeNode id="9" weight="3">
    <TreeNode id="11" weight="2"/>
    <TreeNode id="12" weight="2"/>
   </TreeNode>
   <TreeNode id="10" weight="2"/>
  </TreeNode>
  <TreeNode id="4" weight="2"/>
  <TreeNode id="5" weight="2"/>
 </TreeNode>
</Tree>

I need to flatten the tree to a structure that looks like this. I've
looked at the archives, but haven't found an answer.

<?xml version="1.0"?>
<Tree>
  <TreeNode id="1" weight="5">
    <TreeNode id="2" weight="3"/>
    <TreeNode id="3" weight="4"/>
    <TreeNode id="4" weight="2"/>
    <TreeNode id="5" weight="2"/>
    <TreeNode id="6" weight="2"/>
    <TreeNode id="7" weight="2"/>
    <TreeNode id="8" weight="2"/>
    <TreeNode id="11" weight="2"/>
    <TreeNode id="12" weight="2"/>
    <TreeNode id="9" weight="3"/>
    <TreeNode id="10" weight="2"/>
  </TreeNode>
</Tree>

Any help is appreciated.

Thanks,

-Farooq.
