read xml-file - can't find out if node has childnodes

hi oliver,

you can download MSXML 4 SP2 from the URL:
"http://www.microsoft.com/downloads/details.aspx?FamilyID=3144b72b-b4f2-46da-b4b6-c5d7485f2b42&DisplayLang=en".
This package includes the XML SDK where you can find more informations about using MSXML.

Now to your question.
You can use the following model for walking through the DOM.
---snipp ---
IF Node.hasChildNodes THEN
FOR int := 0 TO (Node.childNodes.length - 1) DO BEGIN
.....
END;
---snapp ---

With this example "Node.childNodes" returns a nodeList and you can proof the length of the nodeList (means the individual items).

A way to address the childNodes directly is, to use "item" of the nodeList.

IF Node.hasChildNodes THEN BEGIN
NoOfItems := Node.childNodes.length;
ActNode := Node.childNodes.item(25) => to request the 25. child
END;

Another way to select Nodes is by using the command "selectNodes" or
"selectSingleNode" with an XPath-Query.
IF InDOM.selectNodes('//Books/Book').length > 0 THEN
ActNode := InDOM.selectSingleNode('//Books/Book[2]'); => to choose the second Book-Node within the Books-Element.


Good luck ...
