Question

I want create an xml document with the namepace attributes along the lines of this:

<MyXmlDoC xmlns='http://abc' xmlns:brk='http://123'> 

Using the System.Xml.Linq xml library, iv done this:

     public static XAttribute XmlNamepace()         {             return new XAttribute(XName.Get('xmlns'), 'http://abc');         }          public static XAttribute brkNamepace()         {             return new XAttribute(XNamespace.Xmlns + 'brk', 'http://123');         }   var rootNode = new XElement('MyXmlDoC',XmlNamepace(),brkNamepace()); 

But this produces this error:

The prefix ” cannot be redefined from ” to ‘http://abc‘ within the same start element tag

What am I doing wrong

Answer 1

(From your answer) you need to add the ChildNode with the rt namespace, this should work:

rootNode.Add(new XElement(rt + 'ChildNode', 'Hello'));
