在解析 xml格式的 InputStream,要先转字节码处理下再解析，否则可能会出现上面的错误。

class="java">
public static String InputStreamTOString(InputStream in,String encoding) throws Exception{  
        
        ByteArrayOutputStream outStream = new ByteArrayOutputStream();  
        byte[] data = new byte[4096];  
        int count = -1;  
        while((count = in.read(data,0,2048)) != -1)  
            outStream.write(data, 0, count);  
          
        data = null;  
        return new String(outStream.toByteArray(),"ISO-8859-1");  
    }

==========================================================================

String xmlStr = this.InputStreamTOString(is, "utf-8");
DocumentBuilderFactory dbf=DocumentBuilderFactory.newInstance();
DocumentBuilder db=dbf.newDocumentBuilder();
Document doc=db.parse(new InputSource(new StringReader(xmlStr)));
