java对简单xml的操作

java对xml的操作，对于简单的xml文件，没有二级子节点下面的方法就可以实现：

import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStreamWriter;
import java.util.Iterator;
import java.util.LinkedHashMap;
import java.util.Map;

public class CreateCommonXml {

Map<String, String> map = null;
   
public CreateCommonXml(Map map,String filepath)
{
this.map = new LinkedHashMap<String, String>();
this.map =map;
this.writeToXml(filepath);
}

public void writeToXml(String filename) {
//FileWriter out;
OutputStreamWriter out;
FileOutputStream fout ;

try {
fout = new FileOutputStream(new File(filename));
out = new OutputStreamWriter(fout,"UTF-8");
out.write("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n");

Iterator<?> it = map.keySet().iterator();

while (it.hasNext()) {
String key = (String) it.next();

String text = "<" + key + ">" + (String) map.get(key) + "</" + key + ">\n";

System.err.println(text);

out.write(text);
}

out.write("\n");

out.flush();

out.close();

} catch (Exception e) {
e.printStackTrace();
}

   }
