XML DOM length attribute
Definition and usage
The length property can return the number of nodes in the NamedNodeMap.
Syntax
nodemapObject.length
Example
In all examples, we will use the XML file books.xml, as well as the JavaScript function loadXMLDoc().
The following code snippet can obtain the number of attributes in the first <book> element of the XML document:
xmlDoc=loadXMLDoc("books.xml");
var x=xmlDoc.getElementsByTagName('book');
document.write(x.item(0).attributes.length);
Output:
1
