Correct. That is if you were using that inside a form's code behind file.
Obviously "this.NamespaceManager" won't be available once you're confronted with the xml output and the xml output only in some other application/environment/solar system for that matter.

If I remember correctly I solved the problem by loading the whole xml data into an XmlDocument and reading the top node's namespace(s). I consider it more as a work around than a viable option but it works nonetheless.

Whenever I have to select a node within code, from either the main data source or a secondary data source, I use the following:

From Main Data Source:

XPathNavigator nav = this.MainDataSource.CreateNavigator();
XPathNavigator node = nav.SelectSingleNode("/my:myFields/my:field1", this.NamespaceManager);

From Secondary Data Source:

XPathNavigator nav = this.DataSources["DataSourceName"].CreateNavigator();
XPathNavigator node = nav.SelectSingleNode("[insert xpath query here]", this.NamespaceManager);

I created a small workaround to read the proper uri for the "my" namespace first.
Still I'm wondering if that's the way to go here.

Xml Namespace problem when using Submit To Hosting Environment

hello everyone,

I'm unable to select a single node within my xml document :-/
http://msdn.microsoft.com/en-us/library/aa701078.aspx

protected void XmlFormView1_Initialize(object sender, 
   InitializeEventArgs e)
{
    // Create an XPathNavigator positioned at the root of the form's main data source.
    XPathNavigator xNavMain = XmlFormView1.XmlForm.MainDataSource.CreateNavigator();
    // Create an XmlNamespaceManager and add the "my" namespace alias from the form's main data source.
    XmlNamespaceManager xNameSpace = new XmlNamespaceManager(new NameTable());
    xNameSpace.AddNamespace("my", "http://schemas.microsoft.com/office/infopath/2003/myXSD/2006-04-20T16:26:21");
    // Create an XPathNavigator positioned on the form's field2.
    XPathNavigator fTextBox1 = xNavMain.SelectSingleNode("my:myFields/my:field2", xNameSpace);
    // Set the form's field2 to the value in TextBox1.
    fTextBox1.SetValue(TextBox1.Text);
}

First of all... my uri for the "my" namespace is different as Infopath seems to create a new uri for each xml document.
I therefore tried to use xNavMain.LookupNamespace("my")... but that doesn't return much (null).

xNavMain.SelectSingleNode("/myFields/my:forename", xNameSpace); always returns null.

The XML as returned by XPathNavigator xNavMain = XmlFormView1.XmlForm.MainDataSource.CreateNavigator();

</my:myFields>

It looks okay, right?
