NamespaceFilter

public class NamespaceFilter extends XMLFilterImpl

NamespaceFilter will take a namespace URI and replace all occurences of that URI with a newer, supplied URI. This effectively allows on-the-fly namespace changes.

Fields Summary
private String
oldURI
The old URI, to replace
private String
newURI
The new URI, to replace the old URI with
Constructors Summary
public NamespaceFilter(XMLReader reader, String oldURI, String newURI)

This will take the XMLReader to use as a parent, as well as the URI to replace, and the URI to replace it with.

param
reader XMLReader to be this filter's parent.
param
oldURI URI to replace occurrences of.
param
newURI URI to replace with.

        super(reader);
        this.oldURI = oldURI;
        this.newURI = newURI;
