Source: DynamDOM.frm

This sample application creates a simple, but complete, XML DOM object, with <root> as the document element. This element contains three child elements: <node1>, <node2>, and <node3>. The first child element contains character data. The second child element contains a CDATA section. The last child element contains three empty child elements: <subnode1>, <subnode2>, and <subnode3>.

To add dynamDOM.frm to the project

  • Copy the code listing above. Paste it into the Visual Basic code editor as the form_load subroutine, replacing any code fragments that are already there.

Next, run the project. The result should be output.
