Jdom的SAXBuilder解析String形式的XML

最近在搭webservice服务，发现SAXBuilder.build的参数没有string类型，有点小伤感，但是直觉告诉我，肯定有个中转站。。。。搜索一番。。。。。ByteArrayInputStream，好吧

private Document XMLString2Document(String XMLString){   
        
        Document document = null;   
        ByteArrayInputStream xmlStream = null;
 
        try{   
            xmlStream=new ByteArrayInputStream(XMLString.getBytes("UTF-8"));   
        }   
        catch(UnsupportedEncodingException uee){   
            uee.printStackTrace();   
        }   
 
        if(xmlStream!=null){   
            try{   
                SAXBuilder saxBuilder=new SAXBuilder();   
                document=saxBuilder.build(xmlStream);   
            }   
            catch(IOException ex){   
                ex.printStackTrace();   
            }   
            catch(JDOMException ex){   
                ex.printStackTrace();   
            }   
        }  
        return document;   
}
