TDOMNode.LookupPrefix function
Locates the Prefix for the specified NameSpace URI.
Declaration
function LookupPrefix(const nsURI: DOMString): DOMStringArguments
nsURI | Namespace URI to locate in the Namespace information. |
Function result
Prefix for the Namespace URI, or an empty string.
Description
LookupPrefix is a
DOMString function used to locate the
Prefix associated with the NameSpace URI specified in the nsURI
argument. LookupPrefix implements the DOM Node interface specified in the DOM
Level 3 specification.
In TDOMNode, the return value is always an empty DOMString ('').
Descendent classes which implement a specific DOM Node specialization (like
TDOMElement) will provide an InternalLookupPrefix
method used to get the return value. The internal
GetAncestorElement routine is used to find Prefix / Namespace
associations in ancestor nodes.
