java读写xml的问题
我用javax.xml等等java自带的包去读写xml，读出来都没什么问题。可是写就有问题了
本来我的xml文件是
<IIsWebServer Location ="/LM/W3SVC/1"
AppPoolId="DefaultAppPool"
DefaultDoc="Default.htm,Default.asp,index.htm,iisstart.htm"
ServerBindings=":80:
  192.168.0.1"
ServerComment="Default Web Site"
ServerSize="1"
>
</IIsWebServer>
结果在写到文件里面都成了

<IIsWebServer AppPoolId="DefaultAppPool" Location "/LM/W3SVC/1"DefaultDoc="Default.htm,Default.asp,index.htm,iisstart.htm"
ServerBindings=":80:" ServerComment="Default Web Site" ServerSize="1"
>
</IIsWebServer>
该换行的都不换行了，而且属性的位置也不一致了(这个倒无所谓)，主要是
ServerBindings=":80:
  192.168.0.1"
这样的数据，没有换行我的iis服务就不认识了。不知道怎么才能让""里面的内容换行呢？


------解决方案--------------------
// 以下设置输出的自动换行和缩进
transformer .setOutputProperty(OutputKeys.INDENT, "yes");

------解决方案--------------------
try
{
String context="";
String str="";
File file=new File("f:\\job.txt");// 文件名你自己设
FileReader fReader=new FileReader(file);
BufferedReader bReader=new BufferedReader(fReader);
while((str=bReader.readLine())!=null)
{
context=context+str+"\r\n";
}
bReader.close();
fReader.close();
File file1=new File("f:\\jobCopy.txt"); //新写成的文件名你自己设
FileWriter fWriter=new FileWriter(file1);
BufferedWriter bWriter=new BufferedWriter(fWriter);
bWriter.write(context);

bWriter.close();
fWriter.close();










}

catch(IOException e)
{
System.out.println("IO Failed!");
}
------解决方案--------------------
建议用dom4j去读写xml文件
------解决方案--------------------
用JDOM 
SAXBuilder builder = new SAXBuilder();
Document Doc = builder.build("D://temp/10.xml");
XMLOutputter XMLOut = new XMLOutputter(); 
String ss = XMLOut.outputString(Doc);

public static String createFile(String ss){
String strUrl = null;
try{
File f = new File("D:\temp");
File file = File.createTempFile("temp", ".xml", f);
if(file.exists()){
strUrl =file.getCanonicalPath();
}
BufferedWriter writer = new BufferedWriter(new FileWriter(file));
writer.write(ss);
writer.close();
}catch(IOException e){
e.printStackTrace();
}
return strUrl;
}
------解决方案--------------------
可以用xsl进行设置格式
------解决方案--------------------
换种思路,可否对
ServerBindings=":80: 
192.168.0.1"
进行一下处理
