Question

I have a DataSet with data that I output (write) to an XMl file.

I have added a namespace and prefix to the dataset like this:

public static string XmlNamespace = "http://namespace";
public static string XmlPrefix = "ns0";
RequestDataSet.Namespace = XmlNamespace;
RequestDataSet.Prefix = XmlPrefix;

The XML output is as follows:

<?xml version="1.0" standalone="yes"?>
<ns0:list xmlns:ns0="http://namespace">
  <ns0:item xmlns="http://namespace">
    <data1>1234</data1>
    <data2>91011</data2>
  </item>
</ns0:list>

But it should be like this: (no namespace on the item records. Just the prefix)

<?xml version="1.0" standalone="yes"?>
<ns0:list xmlns:ns0="http://namespace">
  <ns0:item>
    <data1>1234</data1>
    <data2>91011</data2>
  </item>
</ns0:list>

I have tried setting the tables prefix/namespace to null like this:

RequestDataSet.Tables["item"].Prefix = XmlPrefix;
RequestDataSet.Tables["item"].Namespace = null;

But that also does not work… Does anyone know a solution for this?

I’ve come across similar issues when fighting with BizTalk adapters… but that’s a different story.

Not sure if there is a different (cleaner) way, but you could always ‘grab’ the attribute and remove it, as decribed here.

Effectively you would do the following:

XmlDocument xDoc = new XmlDocument();
    xDoc.LoadXml(xml);
    if (xDoc.DocumentElement.Attributes.Count > 0)
    {
        XmlAttribute xAtt = xDoc.DocumentElement.Attributes[0];
        xDoc.DocumentElement.Attributes.Remove(xAtt);
