关于jdom怎么解析XML流

Question

大侠门帮帮忙：关于jdom怎么解析XML流，我之前用jdom解析的是XML文件，现在要解析xml流要怎么解析？(我试过把原来解析文件的参数Document read_doc=builder.build("Assist.xml")改成Document read_doc=builder.build(str)　str是XML流字符串型式,解析会出错，请问要怎么解析？)

Answer 1

SAXBuilder builder=new SAXBuilder();
       Document read_doc=builder.build("agAssistgetBulletin.xml");
       Element root=read_doc.getRootElement();
       Element cont = root.getChild("Content");
       List list=cont.getChildren("Bulletin");
       for(int i=0;i<list.size();i++){
           Element e=(Element)list.get(i);
           String bull_name=e.getChildText("Subject");
           String bull_dept=e.getChildText("PublishDept");
           String bull_date=e.getChildText("PublishDate");
           System.out.println("---------Bulletin--------------");
           System.out.println("NAME:"+bull_name);
           System.out.println("DEPT:"+bull_dept);
           System.out.println("DATE:"+bull_date);
           System.out.println("------------------------------");
           System.out.println();
这是偶解析XML文件的函数，解析XML流，要怎么写？(帮帮忙，急)
