I would use LINQ to SQL(mydatasource assumed SQL) then LINQ to XML then XSLT to get the exact XML you are looking for.

Here is an example: My XML

<Promotions> 
      <Promotion> 
        <Category>Arts &amp; Entertainment</Category> 
        <Client>Client 1</Client> 
        <ID>2</ID> 
        <Title>Get your Free 2</Title> 
      </Promotion> 
      <Promotion> 
        <Category>Community &amp; Neighborhood</Category> 
        <Client>Client1</Client> 
        <ID>4</ID> 
        <Title>Get your Free 4</Title> 
      </Promotion> 
      <Promotion> 
        <Category>Community &amp; Neighborhood</Category> 
        <Client>Client 1</Client> 
        <ID>5</ID> 
        <Title>Get your Free 5</Title> 
      </Promotion> 
      <Promotion> 
        <Category>Community &amp; Neighborhood</Category> 
        <Client>Client 2</Client> 
        <ID>1</ID> 
        <Title>Get your Free 1</Title> 
      </Promotion> 
      <Promotion> 
        <Category>Education</Category> 
        <Client>Client 3</Client> 
        <ID>3</ID> 
        <Title>Get Your Free 3</Title> 
      </Promotion> 
      <Promotion> 
        <Category>Home &amp; Garden</Category> 
        <Client>Client 4</Client> 
        <ID>6</ID> 
        <Title>Get your Free 6</Title> 
      </Promotion> 
    </Promotions> 

My code:

 PromotionsDataContext db = new PromotionsDataContext();
                        //load sql into XML for tree view js control
                        XElement Categories =
                            new XElement("Promotions",
                                from b in db.Promotion_GetPromotions()
                                select new XElement("Promotion",
                                    new XElement("Category", b.CategoryName),
                                       new XElement("Client", b.ClientName),
                                       new XElement("ID", b.ID),
                                       new XElement("Title", b.Title)));

                        XDocument mydoc = new XDocument();
                        mydoc.Add(Categories);

                        try
                        {

                        // Load the style sheet.
                        XslCompiledTransform xslt = new XslCompiledTransform();
                        xslt.Load(@"C:\TransList.xslt");

                        // Execute the transform and output the results to a writer.
                        StringWriter sw = new StringWriter();
                        //XsltSettings mysettings = new XsltSettings();
                        XmlWriterSettings mysettings = new XmlWriterSettings();

                        xslt.Transform(mydoc.CreateReader(), null, sw);

My XSLT file:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:asp="http://schemas.microsoft.com/ASPNET/20">


  <xsl:output method="html" indent="yes" />

  <xsl:key name="categories" match="Category" use="." />
  <xsl:key name="client" match="Client" use="." />
  <xsl:key name="title" match="Title" use="." />

  <xsl:template match="/">

    <ul id="red" class="treeview-red">
      <xsl:for-each select="/Promotions/Promotion/Category[  
                generate-id(.) = generate-id(key('categories', .)[1])  
                ]">
        <li>
          <span>
            <xsl:value-of select="."/>
            <!--Category-->
          </span>

          <ul>
            <xsl:call-template name="category-client">
              <xsl:with-param name="category" select="."/>
              <!--Client-->
            </xsl:call-template>
          </ul>
        </li>

      </xsl:for-each>
    </ul>

  </xsl:template>

  <xsl:template name="category-client">
    <xsl:param name="category" />
    <xsl:for-each select="/Promotions/Promotion[Category=$category]/Client[  
                generate-id(.) = generate-id(key('client', .)[1]) 
                ]">
      <li>
        <span>
          <xsl:value-of select="."/>
        </span>
        <ul>
          <xsl:call-template name="category-client-title">
            <xsl:with-param name="category" select="$category"/>
            <!--Title-->
            <xsl:with-param name="client" select="."/>
          </xsl:call-template>
        </ul>
      </li>
    </xsl:for-each>
  </xsl:template>

  <xsl:template name="category-client-title">
    <xsl:param name="category" />
    <xsl:param name="client" />
    <xsl:for-each select="/Promotions/Promotion[Category=$category]/Title[  
                generate-id(.) = generate-id(key('title', .)[1]) 
                ]">
      <li>
        <span>
          <asp:LinkButton ID ="LinkButton{../ID}" runat="server" OnClick="LinkClicked" Text="{.}">
          </asp:LinkButton>
        </span>
      </li>

    </xsl:for-each>

  </xsl:template>

</xsl:stylesheet>

Here are some things I found when working with XSLT in C#:

What am I doing wrong here, having issues with XSLT using C#

How do I retrieve a sibling by tag name in XSLT?

XSLT renders &gt; and &lt; for >< how to do I get around this?

Answer 2

If I have a project which intensively works with Xml, I always create a VB Project. You could declare the sample xml like:

Dim sampleXml = 
<Promotions> 
      <Promotion> 
        <Category>Arts &amp; Entertainment</Category> 
        <Client>Client 1</Client> 
        <ID>2</ID> 
        <Title>Get your Free 2</Title> 
      </Promotion> 
      <Promotion> 
        <Category>Client 1</Category> 
        <Client>Artsquest</Client> 
        <ID>4</ID> 
        <Title>Get your Free 4</Title> 
      </Promotion> 
      <Promotion> 
        <Category>Client 1</Category> 
        <Client>Artsquest</Client> 
        <ID>5</ID> 
        <Title>Get your Free 5</Title> 
      </Promotion> 
      (....)

and retrieve an item like:

Dim firstPromotion = sampleXml.Promotions.Promotion(0)

or something similar.

Even if I have a C# project, I create an VB dll-project to work with xml. It is much cleaner than the newXElement stuff you have to do in C#.
