关于加载XML的问题

Java code:
response.setContentType("text/xml; charset=UTF-8");

path=path+"config\\gridnews.xml";
path.replace("\\","\\\\");
System.out.println(path);
File list = new File(path);
list.createNewFile();
FileWriter fw =new FileWriter(list);
fw.write("<?xml version="+'"'+"1.0"+'"'+" encoding="+'"'+"UTF-8"+'"'+"?>");
fw.write("<all_info>");
fw.write("<news>"+news+"</news>");
fw.write("</all_info>");
