XML DOM hasChildNodes() Method
Element Object
Definition and Usage
The hasChildNodes() method returns TRUE if the current element node has child nodes, and FALSE otherwise.
Syntax
elementNode.hasChildNodes()
Example
The following code fragment loads "books.xml" into xmlDoc using loadXMLDoc() and checks if the first <book> element has any child nodes:
Example
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName("book")[0];
document.write(x.hasChildNodes());
x=xmlDoc.getElementsByTagName("book")[0];
document.write(x.hasChildNodes());
Output:
true
