Script Syntax

boolValue = oXMLDOMNode.hasChildNodes();

Return Value

Boolean. Returns True if this node has children.

Example

The following script example checks a node to see if it has any child nodes. If it does, it displays the number of child nodes it contains.

var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.5.0");
var currNode;
xmlDoc.async = false;
xmlDoc.load("books.xml");
if (xmlDoc.parseError.errorCode <> 0) {
   var myErr = xmlDoc.parseError;
   alert("You have error " + myErr.reason);
} else {
   currNode = xmlDoc.documentElement.firstChild;
   if (currNode.hasChildNodes()) {
      alert(currNode.childNodes.length);
   } else {
      alert("no child nodes");
   }
}
