System.Xml.XmlNodeReader.GetAttribute Method

Syntax

public override string GetAttribute (string name, string namespaceURI)

name
The local name of the attribute.
namespaceURI
The namespace URI of the attribute.

The value of the specified attribute. If the attribute is not found, null is returned.

Remarks

Note:

In the dnprdnext, the recommended practice is to create System.Xml.XmlReader instances using the System.Xml.XmlReaderSettings class and the erload:System.Xml.XmlReader.Create method. This allows you to take full advantage of all the new features introduced in the dnprdnshort. For more information, see Creating XML Readers.

The following XML contains an attribute in a specific namespace:

Example

<test xmlns:dt="urn:datatypes" dt:type="int"/>

You can lookup the dt:type attribute using one argument (prefix and local name) or two arguments (local name and namespace URI):

Example

String dt = reader.GetAttribute("dt:type");
String dt2 = reader.GetAttribute("type","urn:datatypes");

To lookup the xmlns:dt attribute, use one of the following arguments:

Example

String dt3 = reader.GetAttribute("xmlns:dt");
String dt4 = reader.GetAttribute("dt",http://www.w3.org/2000/xmlns/);

You can also get this information using the XmlNodeReader.Prefix property.
