[jdom-interest] [Fwd: JDOM ?]

[Dennis Sosnoski]

The SAX specification says that parser instances are reusable: 
http://www.saxproject.org/apidoc/org/xml/sax/XMLReader.html#parse(org.xml.sax.InputSource):
"Once a parse is complete, an application may reuse the same XMLReader 
object, possibly with a different input source."
