Examples of org.apache.cocoon.xml.dom.DOMStreamer

org.apache.cocoon.xml.dom.DOMStreamer
The DOMStreamer is a utility class that will generate SAX events from a W3C DOM Document.
The DOMStreamer uses a different strategy based on the value of the normalizeNamespaces property:
- if true (the default), the DOMStreamer will normalize namespace declarations (i.e. add missing xmlns attributes or correct them). See also {@link NamespaceNormalizingDOMStreamer}.
- if false, the standard JAXP identity transformer is used.
