removing namespace from xml

I have an xml as shown:

<?xml version="1.0" encoding="utf-8"?>
<Query_advanced>
<Query>hy</Query>
  <Attribute Name1="Patient's Age" Value1="23" xmlns="xyz"/>
  <Attribute Name1="Patient's Birth Date" Value1="24/12/1988" xmlns="xyz"/>
  <Attribute Name1="Patient's Name" Value1="xyz" xmlns="xyz" />
</Query_advanced>

I need to read through the xml to get the values of Name1 and of Value1, but im unable to do so with the xmlns there. Is there any way i co开发者_开发问答uld do so? Ive tried using:

XmlNamespaceManager xnm = new XmlNamespaceManager(xdoc.NameTable);
xnm.RemoveNamespace("Attribute", "xyz");

I think you've not to remove the namespace, but you've to add it to the XmlNameSpaceManager, in order to use a prefix (as @John Saunders comments), for example, in a XPath expression.

Try this:

XmlNamespaceManager xnm = new XmlNamespaceManager(xdoc.NameTable);
xnm.AddNamespace("a", "xyz");

// Cycle through the Attribute nodes
foreach (XmlNode node in xdoc.SelectNodes("//Query_advanced/a:Attribute", xnm)) 
{
    // And read the attributes of the node
    string NameAttribute = node.Attributes["Name1"].Value;
    string ValueAttribute = node.Attributes["Value1"].Value;
}

Use XmlReader or XmlTextReader if you have a file.

Here an example: http://msdn.microsoft.com/en-us/library/cc189056(v=vs.95).aspx

In your example Attribute is a xml tag, not a namespace. Name1 and Value1 are xml attributes of the tag Attribute.

So you need to read the attributes of the tag Attribute.

Let xmlString is the xml you want to parse:

using (XmlReader reader = XmlReader.Create(new StringReader(xmlString)))
{
    while(reader.ReadToFollowing("Attribute")){ //loop read Attribute tag
       reader.MoveToFirstAttribute();
       string Name1 = reader.Value; //do something with Name1
       reader.MoveToNextAttribute();
       string Value1 = reader.Value; //do something with Value1
    }
}

THanks for all your suggestions! I managed to do it this way:

private void QueryXML() {

        XmlDocument query_xml = new XmlDocument();
        query_xml.Load("Query_1.xml");
        XmlNodeList elements = query_xml.GetElementsByTagName("Attribute");
        string[] s = new string[elements.Count];


        for (int i = 0; i < elements.Count; i++)
        {
            string attrVal = elements[i].Attributes["Value1"].Value;
        Console.Writeline(attrval)

}

Thanks a bunch! :)
