Description

There is function getNamespaceURI(String prefix), but there is no inverted one.

Need this in following case:

• reading XML
• check, if prefix for particular namespace is defined (using getPrefix)
• if defined - using prefix, specified in XML
• if not defined - define prefix and using it

Usual way - to define prefix always - is not good, since prefix can already be used in XML file with another namespace.
