parse

public StructuredQName parse(java.lang.CharSequence lexicalName)
                      throws XPathException

Make a structured QName from a lexical QName, using a supplied NamespaceResolver to resolve the prefix. The local part of the QName is checked for validity; the prefix is not checked, on the grounds that an invalid prefix will fail to resolve to a URI.

Parameters:

lexicalName - the QName as a lexical name (prefix:local)

Returns:

the StructuredQName object corresponding to this lexical QName

Throws:

XPathException - if the namespace prefix is not in scope or if the value is lexically invalid. Error code FONS0004 is set if the namespace prefix has not been declared; error code FOCA0002 is set if the name is lexically invalid. These may need to be changed on return depending on the caller's requirements.
