Fixed version (ground truth):

  IProject fsProject=null;
  try {
    fsProject=ResourceUtils.getProject(project.getTechnicalLabel());
  }
 catch (  PersistenceException e2) {
    ExceptionHandler.process(e2);
  }
  if (fsProject == null) {
    return null;
  }
  String temPath=fsProject.getLocationURI().getPath() + File.separator + "String_Node_Str";
  String fileName="String_Node_Str";
  String pathStr=connection.getXmlFilePath();
  if (connection.isContextMode()) {
    ContextType contextType=ConnectionContextHelper.getContextTypeForContextMode(connection,true);
    pathStr=TalendQuoteUtils.removeQuotes(ConnectionContextHelper.getOriginalValue(contextType,pathStr));
  }
  if (pathStr != null && XmlUtil.isXMLFile(pathStr)) {
    fileName=StringUtil.TMP_XML_FILE;
  }
 else   if (pathStr != null && XmlUtil.isXSDFile(pathStr)) {
    fileName=StringUtil.TMP_XSD_FILE;
  }
 else   if (pathStr.contains("String_Node_Str")) {
    fileName=new Path(pathStr).lastSegment();
  }
  File temfile=new File(temPath + File.separator + fileName);
  if (!temfile.exists()) {
    try {
      temfile.createNewFile();
