validating Xhtml Strict with Csharp

[harshmaul]

Hi all,

I am writing a form for end users to input XHTML that will be displayed on the site.

I know that is way too much trust for my users but what can you say you gotta do what the boss wants. Anyway ...

How do i validate the input, i "intelisens e browsed" and i worked out how to validate xml, but i can't get it to change the schema it uses.

This is the standard xml parser.

        XmlDocument xmld = new XmlDocument();
        try
        { xmld.LoadXml(TextBox1.Text);}
        catch (Exception exc)
        {Response.Write(exc.Message.ToString()); }

This is my attempt at loading in the dtd from w3c

        XmlSchemaSet sch = new XmlSchemaSet();
        XmlSchema xmlSch = new XmlSchema();
        XmlSchemaSet schcopy = new XmlSchemaSet();

        xmlSch.SourceUri = "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";
        xmlSch.Namespaces.Add("xmlns", "http://www.w3.org/1999/xhtml");
        sch.Add(xmlSch);

All the later does is stop working when i step through when it reaches the SourceUri line of the code.

If anyone can help me i would be grateful...
