XML DOM length Property
NodeList Object
Definition and Usage
The length property returns the number of nodes in a node list.
Syntax
nodelistObject.length
Example
The following code fragment loads "books.xml" into xmlDoc using loadXMLDoc() and gets the number of <title> elements:
Example
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName('title');
document.write("Number of title elements: " + x.length);
x=xmlDoc.getElementsByTagName('title');
document.write("Number of title elements: " + x.length);
The output of the code above will be:
Number of title elements: 4
