Requirements

• The require() method asserts that the current event has a certain type, local name, and namespace URI:

  public void require(int type, String namespaceURI, String localName) throws XMLStreamException

• If the event does not have the right name and URI, an XMLStreamException is thrown.

• You can pass null for the local name or namespace URI, to match any local name/namespace URI.

• This is useful for in-process validation.
