Question

我在使用android进行xml解析时面临一些问题。问题是来自服务器的xml带有“ISO-8859-1”设置为setEncoding（我得到<?xml version="1.0" encoding="ISO-8859-1"?>）格式，并且android设备似乎忽略了该编码。

例如，这是来自服务器的原始xml的一部分：

<Result Filename="Pautas para la Presentación RUP Iteraciones de Construcción.ppt">
        <Path>C:\Documents and Settings\zashael\My Documents\PFC\RUP\Pautas para la Presentación RUP Iteraciones de Construcción.ppt</Path>
        <Hostname>computer_1</Hostname>
        <IP>192.168.0.5:27960</IP>
        <ModDate>01-ene-1601 2:06:34</ModDate>
        <Size>33.280 bytes</Size>
    </Result>

这是我在解析xml之前得到的电话：

</Result>
 <Result Filename="Pautas para la Presentaciï¿½n RUP Fase Inicio.ppt">
     <Path>C:\Documents and Settings\zashael\My Documents\PFC\RUP\Pautas para la Presentaciï¿½n RUP Fase Inicio.ppt</Path>
     <Hostname>computer_1</Hostname>
     <IP>192.168.0.5:27960</IP>
     <ModDate>01-ene-1601 1:32:06</ModDate>
    <Size>26.624 bytes</Size>
 </Result>

正如您所看到的，“presentación”这个词有问题。

这是我接收文件的代码部分，然后将其发送给解析器：

do
                    {
                        auxMessage = ois.readObject();

                        if (auxMessage instanceof ComConstants)
                        {
                            receivedMessage = (ComConstants) auxMessage;

                            Log.d("Client", "Client has Search Results"); 

                         //Charset charset = Charset.forName("ISO-8859-1"); 
                         //CharsetDecoder decoder = charset.newDecoder(); 
                         //CharsetEncoder encoder = charset.newEncoder(); 



                            String test;

                            test = new String(
                                    receivedMessage.fileContent, 0,
                                    receivedMessage.okBytes);

                            if (finalMessage == null) {
                                finalMessage = test;
                            }
                            else {                          
                                finalMessage += test;
                            }


                         /*try { // Convert a string to ISO-LATIN-1 bytes in a ByteBuffer 
                             // The new ByteBuffer is ready to be read. 
                             ByteBuffer bbuf = encoder.encode(CharBuffer.wrap(finalMessage)); 
                             // Convert ISO-LATIN-1 bytes in a ByteBuffer to a character ByteBuffer and then to a string. 
                             // The new ByteBuffer is ready to be read. 
                             CharBuffer cbuf = decoder.decode(bbuf); 
                             String s = cbuf.toString(); 

                            finalMessage = s;

                             } 

                         catch (CharacterCodingException e) { } 
                         }*/

                        }
                         else
                        {
                            Log.d("Client", "Unexpected message "
                                    + auxMessage.getClass().getName()); 

                            break;
                        }
                    } while (!receivedMessage.lastMessage);


                    //test encoding
                    //String s = finalMessage;
                    //finalMessage = new  String(s.getBytes("ISO-8859-1"));


                    System.out.println("antes de parsear" + finalMessage);

                    SaxParser sap = new SaxParser(finalMessage);

这是我的解析器代码：

                tempResults.setSize((tempVal)); 
                }       
        }


}

我不知道该怎么做。我在收到xml字节到ISO编码后尝试设置我创建的字符串，但我唯一得到的是“square”而不是“ón”。

比你！

Answer 1

服务器可以说它是ISO-8859-1，但它看起来像是在发送UTF-8。

如果您可以控制服务器代码，请确保正确设置输出流上的编码。只需添加<?xml version="1.0" encoding="ISO-8859-1"?>标头，就不会导致输出的编码正确。
