Class OMXMLReader

java.lang.Object

org.apache.axiom.om.impl.serialize.OMXMLReader

All Implemented Interfaces:

XMLReader

public class OMXMLReader
extends Object
implements XMLReader

SAX XMLReader implementation that traverses a given OM tree and invokes the callback methods on the configured ContentHandler. This can be used to serialize an Axiom tree to SAX.

Note that this class doesn't support serializing OMDocType nodes. They will be silently skipped.

This class can also generate SAX events for a subtree. This is the case if the element passed to the constructor is not the root element of the document. In this case, care is taken to properly generate startPrefixMapping and endPrefixMapping events also for namespace mappings declared on the ancestors of the element.

To understand why this is important, consider the following example:

<root xmlns:ns="urn:ns"><element attr="ns:someThing"/><root>

In that case, to correctly interpret the attribute value, the SAX content handler must be aware of the namespace mapping for the ns prefix, even if the serialization starts only at the child element.
