How to build XmlNodes from XmlReader

.net-2.0, c#, xml, xmlreader

Solution

The `XmlNode` type does not have a public constructor, so you cannot create them on your own. You will need to have an `XmlDocument` that you can use to create them:

XmlDocument doc = new XmlDocument();
while (xmlReader.Read())
{
    //keep reading until we see my element
    if (xmlReader.Name.Equals("myElementName") && (xmlReader.NodeType == XmlNodeType.Element))
    {
        // How do I get the Xml element from the reader here?
        XmlNode myNode = doc.CreateNode(XmlNodeType.Element, xmlReader.Name, "");
        nodeList.Add(myNode);
    }        
}

Problem

I am parsing a big number of big files and after profiling my bottleneck is: ``` XmlDocument doc = new XmlDocument(); doc.Load(filename); ``` This approach was very handy because I could extract nodes like this: ``` XmlNodeList nodeList = doc.SelectNodes("myXPath"); ``` I am switching to XmlReader, but When I find the element I need to extract I am stuck with regards to how to build a XmlNode from it as not too familiar with XmlReader: ``` XmlReader xmlReader = XmlReader.Create(fileName); while (xmlReader.Read()) { //keep reading until we see my element if (xmlReader.Name.Equals("myElementName") && (xmlReader.NodeType == XmlNodeType.Element)) { // How do I get the Xml element from the reader here? } } ``` I'd like to be able to build a `List<XmlNode>` object. I am on .NET 2.0. Any help appreciated!
