Microsoft DOM Objects Reference

hasChildNodes()

Syntax

blnValue = objXMLDOMNode.hasChildNodes()

Remark

This method is read-only. This method returns a boolean indicating whether the current Node has any children. It can be used instead of the length property, as explained earlier in this chapter.

Example

We have snatched the following example from the length property and changed it to show how to use the hasChildNodes() method.

In this example, we test the hasChildNodes() method to see if a DOMDocument has loaded properly. If the hasChildNodes() returned True, then we can proceed with the rest of the code working with the DOMDocument object.

Dim objDOMDocument As DOMDocument

Dim objNode As IXMLDOMNode

Set objDOMDocument = New DOMDocument

objDOMDocument.async = False

objDOMDocument.Load "http://localhost/xmlcode/people2.dtd"

If objDOMDocument.hasChildNodes Then

`run rest of code here

End If

Our code has loaded the XML from our main XML example. The hasChildNodes() method returns True; therefore, we can proceed with our DOMDocument.
