XmlDocument xsi: Problem

[Mark Jerde]

I've been looking through MSDN, books and googling for a couple hours but
haven't found the solution yet. I'm using CSharp in VS .NET 2003.

I'm trying to use XmlDocument to save XML files that are valid to a schema
I've developed. I want the root element to look like this:

<TestCase xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="TestCaseSchema_03.x sd">

I've tried several variations of XmlElement.SetAttribute() and "
XmlAttribute att = [XmlDocument].CreateAttribute() " The closest I've
gotten to the desired output is (notice the missing "xsi:"):

<TestCase xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
noNamespaceSchemaLocation="TestCaseSchema_03.xsd">

Many of the things I've tried look more or less like this:

<TestCase xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
d1p1:noNamespaceSchemaLocation="" xmlns:d1p1="TestCaseSchema_03.xsd">

I guess I don't understand DOM well enough to know why these are the
results. Any help will be greatly appreciated!

Thanks.

Hi Mark,

First of all, I would like to confirm my understanding of your issue. From
your description, I understand that you need to create a root node like
<TestCase xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="TestCaseSchema_03.x sd">. If there is any
misunderstanding, please feel free to let me know.

In this case, we can first create an attribute node using
XmlDocument.CreateAttribute() and then add it to the element using
XmlElement.SetAttributeNode() method. Here I wrote some sample code. HTH.

XmlDocument doc = new XmlDocument();
XmlNamespaceManager nsmgr = new XmlNamespaceManager(doc.NameTable);
nsmgr.AddNamespace("xsi", "http://www.w3.org/2001/XMLSchema-instance");

XmlElement ele = doc.CreateElement("TestCase");
XmlAttribute att = doc.CreateAttribute("xsi", "noNamespaceSchemaLocation",
"http://www.w3.org/2001/XMLSchema-instance");
att.Value = "TestCaseSchema_03.xsd";
ele.SetAttributeNode(att);
doc.AppendChild(ele);

Kevin -- Works great. Thanks! I was missing the XmlNamespaceManager and
att.Value.
