org.dom4j.IllegalAddException: The node "your node description..." could not be added to the element "yourNode" because: The Node already has an existing parent of "yourNode"

Document doc = DocumentHelper.createDocument();

Element root = doc.addElement("config")

Element files = root.addElement("files");

String configFiles="<files><file name="AdShower123.exe" oriname="update\adshower123.zip" ver="1.0.0.1" md5="" update="http://soft.51cy.org:80/adv/package/adshower.zip" action="3" param="" op="0" optype="3" opcmd="$(appdir)\AdShower.exe" opparam=""/><file name="AdShower123.exe" oriname="update\adshower123.zip" ver="1.0.0.1" md5="" update="http://soft.51cy.org:80/adv/package/adshower.zip" action="3" param="" op="0" optype="3" opcmd="$(appdir)\AdShower.exe" opparam=""/></files>";

Document fileDom=DocumentHelper.parseText(configFiles);
//root.add(fileDom.getRootElement());
