 Now that XML namespaces are part of HTML Components, Internet Explorer 5.5+ provides a lot of objects, methods, and properties to access these namespaces. XML namespaces is a collection that belongs to the document object. The collection itself is an array object:

oNameSpaceArray = document.namespaces;

To get to a particular namespace object, you can use simple indexing:

oNameSpace = document.namespace[index];

where index starts from 0. You can use string indexing as well. If two namespaces have the same ID or NAME, another integer differentiator is needed:

oNameSpace = document.namespace(sIndex, iSecondary);

The following example uses two namespaces, DOCJS and WEBREF. When we call document.namespace(0) from within the script below, we get the first namespace, DOCJS, as expected.

<HTML XMLNS:DOCJS XMLNS:WEBREF>
<HEAD>
<STYLE>
  @media all {
    DOCJS\:RIGHT {text-align:right; width:100}
  }
</STYLE>
</HEAD>
<BODY>
<DOCJS:RIGHT>

  alert(a1.name);
