(C#) Adding Attributes to an XML Node

Demonstrates how to add attributes to existing XML nodes.

The input XML is this:

<abc>
    <xyz>
        <mmm>123</mmm>
    </xyz>
</abc>

The output XML is this:

<abc a="123">
    <xyz b="456">
        <mmm c="789" d="000">123</mmm>
    </xyz>

Chilkat.Xml xml = new Chilkat.Xml();

bool success;

success = xml.LoadXmlFile("add_attribute.xml");
if (success != true) {
    textBox1.Text += xml.LastErrorText + "\r\n";
    return;
}

//  Add an attribute  a="123" to the root node:
xml.AddAttribute("a","123");

//  Navigate to the 1st child.  After calling FirstChild2,
//  "xml" now references the node with the tag "xyz".
xml.FirstChild2();
xml.AddAttribute("b","456");

//  Navigate to xyz's first child, which is the node having the
//  tag "mmm".
xml.FirstChild2();
xml.AddAttribute("c","789");
xml.AddAttribute("d","000");

//  Revert back to the XML document root node
xml.GetRoot2();

//  Examine the result:
textBox1.Text += xml.GetXml() + "\r\n";
