Obsolete
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.
The Node.prefix read-only property returns the namespace prefix of the specified node, or null if no prefix is specified.
string = node.prefix
The following logs "x" to the console.
<x:div onclick="console.log(this.prefix)"/>
This will only work when a namespace-aware parser is used, i.e. when a document is served with an XML MIME type. This will not work for HTML documents.
