(Chilkat for Android™ API)
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>
</abc>
