Question

当我记录被调用的XML文件的值时，文件每次都在同一个地方结束。它将不完整的数据保存为字符串，然后将其传递给我的XMLfromString函数，该函数出错并显示异常。（见下面的错误）

我想知道是否有任何我需要更改以确保顶部读取整个文件。

    String xml = XMLfunctions.getXML(items);
    Document doc = XMLfunctions.XMLfromString(xml);

public static String getXML(String roomID)
{
    Log.d(TAG, roomID + "PASSED");

    String line = null;

    try 
    {

        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpGet httpPost = new HttpGet("http://mywebsite.com/xml_data/" + roomID + "_meeting_info.xml?id=cacheSTOP3");

        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();
        line = EntityUtils.toString(httpEntity);

    } catch (UnsupportedEncodingException e) {
        line = "<results status=\"error\"><msg>Can't connect to server</msg></results>";
    } catch (MalformedURLException e) {
        line = "<results status=\"error\"><msg>Can't connect to server</msg></results>";
    } catch (IOException e) {
        line = "<results status=\"error\"><msg>Can't connect to server</msg></results>";
    }
    Log.d(TAG, line);
    return line;
}






public final static Document XMLfromString(String xml){

        Document doc = null;

        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        try {

            DocumentBuilder db = dbf.newDocumentBuilder();

            InputSource is = new InputSource();
            is.setCharacterStream(new StringReader(xml));
            doc = db.parse(is); 

        } catch (ParserConfigurationException e) {
            System.out.println("XML parse error: " + e.getMessage());
            return null;
        } catch (SAXException e) {
            System.out.println("Wrong XML file structure: " + e.getMessage());
            return null;
        } catch (IOException e) {
            System.out.println("I/O exeption: " + e.getMessage());
            return null;
        }

        return doc;

    }

我收到的错误消息是：

11-21 11:11:55.456: INFO/System.out(282): Wrong XML file structure: unterminated entity ref (position:ENTITY_REF &@211:21 in java.io.StringReader@44f6a130)

非常感谢任何帮助。

检查你的xml，是否正确，是否有任何关闭的标签。如果可能的话，告诉我们哪一行是282，并发布你的xml。

Android Get XML不返回整个文件
