public class RedundantNamespacesFilter extends org.apache.cocoon.xml.AbstractXMLPipe
A SAX filter that strips out redundant namespace declarations.
It handles both duplicate declarations (i.e. a namespace already declared by a
parent element) and empty namespaces scopes (i.e. start/stopPrefixMapping with
no element inbetween) that can be produced by some components (e.g. JXTG or
BrowserUpdateTransformer). Such empty scopes confuse the Xalan serializer which
then produces weird namespace declarations (xmlns:%@$#^@#="%@$#^@#"
).
This is a the most simple use of NamespacesTable
.
