Class NamespaceHomonymResolver

java.lang.Object

eu.bandm.tools.util.ContentProxy

eu.bandm.tools.util2.NamespaceHomonymResolver

All Implemented Interfaces:

ContentHandler

public class NamespaceHomonymResolver
extends ContentProxy

A ContentHandler which propagates all SAX events but changes "start prefix mapping" and the corresponding "end prefix mapping" iff HOMONMYS (=re-uses of prefices) are detected. ASSUME that all SAX events passing through are in "namespace mode"; ie. get their identity from "localName" and "uri", NOT using qname/prefix! The qname field is NOT adapted according to the calculated re-mapping and must be ignored in all subsequent processing steps. ASSUME that no prefix is re-used on THE SAME level of element nesting! Because in this case the sequential order of the corresponding "end prefix mapping" commands cannot be established.
