Im have a problem. the call to XmlNodeList.nextNode not running:

XmlNode : = xmldom.selectSingleNode('namenode');

XmlNode : = XmlNodeList.item(0);

XmlNode.selectSingleNode('namenode/text()');

REPEAT

IF NOT ISNULL(XmlNode) THEN BEGIN

bigTxTem.ADDTEXT(XmlNode.text);

rec.fieldVarText := XmlNode.text;

rec.insert;

end;

XmlNodeList.nextNode; /// ERROR NO STEP TO NEXT NODE

UNTIL ISNULL(XmlNode);

--------------------

have alternative to extract the text value of estructure of varios "nodes" of same name:

<nodename0>
<nodename1>
    <nodename>Value01</nodename>
</nodename1>
<nodename1>
    <nodename>value02</nodename>
</nodename1>
<nodename1>
    <nodename>value03</nodename>
</nodename1>
</nodename1>

tanks!!

RE: selectSingleNode

Selects THE FIRST XmlNode that matches the XPath expression.

If the XML is what you show here, XmlNode.selectSingleNode('namenode/text()'); is not clear.

If you want to retrieve all nodes values, use something like:

CREATE(XMLDoc);

XMLDoc.load(FileName);

//Gets a list of Items to loop through

XMLNodeList := XMLDoc.selectNodes('//nodename');

FOR Counter := 1 TO XMLNodeList.length DO BEGIN

XMLNode := XMLNodeList.item(Counter-1);

Message('%1',XMLNode.text());

END;
