Class DOMParser

java.lang.Object

      org.milyn.delivery.dom.DOMParser

public class DOMParser
extends AbstractParser

Smooks DOM data stream parser.

This parser can be configured to use a SAX Parser targeted at a specific data stream type. This lets you parse a stream of any type, convert it to a stream of SAX event and so treat the stream as an XML data stream, even when the stream is non-XML.

If the configured parser implements the SmooksXMLReader, the configuration will be passed to the parser via ConfigParam annotaions on config properties defined on the implementation.
