j'utiliser LINQ to SQL (mydatasource supposé SQL) puis LINQ à XML puis XSLT pour obtenir le XML exact que vous êtes à la recherche de.
Voici un exemple: Mon XML
<Promotions>
<Promotion>
<Category>Arts & Entertainment</Category>
<Client>Client 1</Client>
<ID>2</ID>
<Title>Get your Free 2</Title>
</Promotion>
<Promotion>
<Category>Community & Neighborhood</Category>
<Client>Client1</Client>
<ID>4</ID>
<Title>Get your Free 4</Title>
</Promotion>
<Promotion>
<Category>Community & Neighborhood</Category>
<Client>Client 1</Client>
<ID>5</ID>
<Title>Get your Free 5</Title>
</Promotion>
<Promotion>
<Category>Community & 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 & Garden</Category>
<Client>Client 4</Client>
<ID>6</ID>
<Title>Get your Free 6</Title>
</Promotion>
</Promotions>
Mon 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);
Mon fichier XSLT:

<xsl:template match="/">
<ul id="red" class="treeview-red">

Voici quelques choses que j'ai quand on travaille avec XSLT dans 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 > and < for >< how to do I get around this?
