Usage

From source file:Exporters.SaveFileExporter.java

    // TODO - figure out a universal means to get the current version of the generating tool
    // Initial thoughts would be to create a convenience class in Utils package with some
    // final variables that can be updated when issuing a release.
    doc.appendChild(rootElement);/*from  w  w  w. j  a va  2 s  . c o m*/

    Element vulnerabilitiesElement = doc.createElement("vulnerabilities");

            }
        }

    // now write the XML file
