All Implemented Interfaces:

public class TokenXMLExpressionIterator
extends ExpressionAdapter

Expression to walk a Message XML body using an Iterator, which grabs the content between a XML start and end token, where the end token corresponds implicitly to either the end tag or the self-closing start tag.

The message body must be able to convert to InputStream type which is used as stream to access the message body.

Can be used to split big XML files.

This implementation supports inheriting namespaces from a parent/root tag.
