// This example requires Chilkat XML v3.0.0
// Modify the crisp.xml document by relocating some information
// as attributes instead of child nodes.
procedure TForm1.Example3Click(Sender: TObject);
var
  xml: IChilkatXml;
  outXml: IChilkatXml;
  node: IChilkatXml;
  langNode: IChilkatXml;
begin
    xml := CoChilkatXml.Create();
    outXml := CoChilkatXml.Create();


    // Load the input document.
    xml.LoadXmlFile('crisp.xml');


    // Iterate over the "DOC" nodes by calling FirstChild
    // followed by NextSibling2 repeatedly until it returns false.
    node := xml.FirstChild();
    while (node <> nil) do
	   begin
	    langNode := node.FindChild('Language');
	    if (langNode <> nil) then
      begin
	      // Add the language information as an attribute of the "DOC" node.
	      node.AddAttribute('language',langNode.Content);

	      // Remove the "Language" node from the document because the
	      // information is now stored as an attribute of the parent.
	      langNode.RemoveFromTree();

      end;

	    // Move to the next sibling. The internal reference within node is updated
	    // to the node's next sibling. If no siblings remain, it returns 0.
	    if (node.NextSibling2() = 0) then
        node := nil;
    end;
