java.lang.Objectorg.dom4j.io.SAXModifier
The SAXModifier reads, modifies and writes XML documents using SAX.
Registered ElementModifierobjects can provide modifications to (part
of) the xml tree, while the document is still being processed. This makes it
possible to change large xml documents without having them in memory.
The modified document is written when the XMLWriteris specified.
