Grouping by Deparment


Calling all XSL Gurus :-)
 
I need a push in the right direction.  I have an XML file that includes
a list of employees and their respective departments.  I need to loop
through the xml and sort the employees by department alphabetically.
 
I am not sure how to make the (Name) TreeNode element a child element of
the (Department) TreeNode element and then populate all the employees
within that department.
 
My brain hurts...any help would be appreciated.
 
Regards,
 
Jeff Langdon
 
Here is what I have so far -
 
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version='1.0'>
            <xsl:template match="/">
                        <TREENODES>
                                    <xsl:for-each
select="NewDataSet/Table">
                                                <xsl:element
name="TreeNode">
 
<xsl:attribute name="Text">
 
<xsl:value-of select="Department" />
 
</xsl:attribute>
                                                </xsl:element>
                                                <xsl:element

<xsl:attribute name="Text">

                                                </xsl:element>
                                    </xsl:for-each>
                        </TREENODES>
            </xsl:template>
</xsl:stylesheet>
 
Here is the XML file -
 
<NewDataSet>
            <Table>
                        <cn>Acevedo, Antonia</cn>
                        <Department>Dispatch-Freight</Department>
                        <Name>Acevedo, Antonia</Name>
            </Table>
            <Table>
                        <cn>Aimone, Charlie</cn>
                        <Department>IT</Department>
                        <Name>Aimone, Charlie</Name>
            </Table>
            <Table>
                        <cn>Arenas, Lizalyn</cn>
                        <Department>Dispatch-Freight</Department>
                        <Name>Arenas, Lizalyn</Name>
            </Table>
            <Table>
                        <cn>Arrendell, Miguel</cn>
                        <Department>Warehouse</Department>
                        <Name>Arrendell, Miguel</Name>
            </Table>
            <Table>
                        <cn>Bayron, Jun</cn>
                        <Department>Warehouse</Department>
                        <Name>Bayron, Jun</Name>
            </Table>
            <Table>
                        <cn>Belki Hercules</cn>
                        <Department>ITl</Department>
                        <Name>Belki Hercules</Name>
            </Table>
</NewDataSet>
 
Output I am looking for -
 
<TREENODE>
            <TreeNode Text="Dispatch-Frieght">
                        <TreeNode Text="Acevedo, Antonia" />
                        <TreeNode Text="Arenas, Lizalyn" />
            </TreeNode>
            <TreeNode Text="IT">
                        <TreeNode Text="Aimone, Charlie" />
                        <TreeNode Text="Belki, Hercules" />
            </TreeNode>
            <TreeNode Text="Warehouse">
                        <TreeNode Text="Arrendell, Miguel" />
                        <TreeNode Text="Bayron, Jun" />
            </TreeNode>
</TREENODE>
