selectSingleNode

Posted on by 15

HI

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);                 

or

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!!

    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;
