XML DOM compareDocumentPosition() Method
Element Object
Definition and Usage
The compareDocumentPosition() method compares the document position of the current node, with a specified node, according to the document order.
Syntax
elementNode.compareDocumentPostition(node)
| Parameter | Description |
|---|---|
| node | Required. Specifies the node to compare with the current node |
Example
The following code fragment loads "books.xml" into xmlDoc using loadXMLDoc() and compares the first and the third <book> nodes:
Example
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName('book')[0];
y=xmlDoc.getElementsByTagName('book')[2];
document.write(x.compareDocumentPosition(y));
x=xmlDoc.getElementsByTagName('book')[0];
y=xmlDoc.getElementsByTagName('book')[2];
document.write(x.compareDocumentPosition(y));
Output:
4

Firefox, and most other browsers, will treat empty white-spaces or new lines as text nodes, Internet Explorer will not. So, in the example above, Mozilla browsers will output 4, while Internet Explorer will output 2.
