Pankaj Kumar has announced XPB4J, a tool for measuring and comparing XML parsing/processing performance.

According to XPB4J's web site, it "considers XML operations such as parsing, transformation, validation, encryption/decryption, custom access/manipulation or any combination of these applied to one or more XML files and/or byte streams as XML processing."

XPB4J has three components: code to carry out XML processing, a harness to run and measure that processing, and a framework to allow pluggable code and scripts.

A report describing processor measurements is available on the web site, considering Xerces, GNU JAXP, Piccolo, XML Pull parser, JDOM, dom4j.
