if (lst.size()>0){
pDataSrcStruct=(DataSrcStruct)lst.get(0)
//得到xml文件
ServerMgr pServerMgr=new ServerMgr()
String savepath = pServerMgr.getRSCollectDataPath()+ "/" + pDataSrcStruct.getId() + ".xml"
SAXReader saxReader = new SAXReader()
Document document = saxReader.read(new File(savepath))
//使用输出流来进行转化
ByteArrayOutputStream output = new ByteArrayOutputStream()
//使用GB2312编码
OutputFormat format = new OutputFormat(" ", true, "GB2312")

writer.write(document)
String sxml = output.toString("GB2312")
pDataSrcStruct.setXml_info(sxml)

//保存xml格式文件
