Constantly having to traverse from Xml to LinqXml so I’ld though I’ld post the static helper classes I constantly use.

public static class XMLHelper
{
    public static XElement GetXElement(XmlNode node)
    {
        XDocument xDoc = new XDocument();
        using (XmlWriter xmlWriter = xDoc.CreateWriter())
            node.WriteTo(xmlWriter);
        return xDoc.Root;
    }

    public static XmlNode GetXmlNode(XElement element)
    {
        using (XmlReader xmlReader = element.CreateReader())
        {
            XmlDocument xmlDoc = new XmlDocument();
            xmlDoc.Load(xmlReader);
            return xmlDoc;
        }
    }
}

Sending SOAP requests over to a SOAP server can sometimes be problematic. (aren’t they always with an internet standard?) Be wary about the ContentLength property. When your sending over to a .net stubbed service you may not need to specify, however, when sending with variable byte length codepage (UTF-8, 16 etc) your length MUST be the byte length, not the un-paged length.

request.ContentType = "text/xml; charset=utf-8";
request.ContentLength = postData.Length;

Good

request.ContentType = "text/xml; charset=utf-8";
request.ContentLength = System.Text.Encoding.UTF8.GetByteCount(postData);

I’ve had a few emails this week about a post I made about 3 years ago, driving a DHTML menu from a database.
