XML解析：编码UTF-8和; UTF-8 [英] XML parsing : encoding utf-8 & UTF-8

问题描述

我试图解析从这个链接，它的XML编码是这样的

＆LT; XML版本=1.0编码=UTF-8＆GT;

当我试图得到响应抛出logcat的消息显示

  11-19 17：25：13.350：W / System.err的（3360）：这不是合法的URL
11-19 17：25：13.350：W / System.err的（3360）：显示java.lang.NullPointerException
 

当我试着用一些其他的 LINK ，其编码是这样的

＆LT; XML版本=1.0编码=UTF-8＆GT; 它工作正常，我可以分析值

是XML解析失败是由于编码不是UTF-8，这是UTF-8 ??

我应该如何处理这个问题。我做了谷歌，并相信新的XML解析。这是我的，我想创建第一个解析。请让我知道的方式。

更新code：

 公共字符串getXmlFromUrl（字符串URL）{

    XML字符串= NULL;

    尝试 {
        // defaultHttpClient
        HttpClient的HttpClient的=新DefaultHttpClient（）;
        HttpPost httpPost =新HttpPost（URL）;
        HTT presponse HTT presponse = httpClient.execute（httpPost）;
        HttpEntity httpEntity = HTT presponse.getEntity（）;
        XML = EntityUtils.toString（httpEntity）;
        的System.out.println（回应 - + XML）;

    }赶上（UnsupportedEncodingException E）{
        e.printStackTrace（）;
    }赶上（ClientProtocolException E）{
        e.printStackTrace（）;
    }赶上（IOException异常E）{
        e.printStackTrace（）;
    }
    //返回XML
    返回XML;
}
 

解决方案

直线距离它看起来像问题是XML在你的响应编码。

 网​​址URL =新的URL（http://myurl.com）;
InputSource的是=新的InputSource（url.openStream（））;
is.setEncoding（ISO-8859-1）; //也可以尝试UTF-8或UTF-16
的BufferedReader BR =新的BufferedReader（新的InputStreamReader（is.getByteStream（）））;
串线，STR;
而（（行= br.readLine（））！= NULL）
{
      海峡= STR +线;
}
Log.i（TAG，STR）;
 

I am trying to parse the values from this LINK, whose xml encoding is like this

<?xml version="1.0" encoding="utf-8"?>

when I tried to get response throws message in logcat as shown

11-19 17:25:13.350: W/System.err(3360): This is not valid URL
11-19 17:25:13.350: W/System.err(3360): java.lang.NullPointerException

When I tried with some other LINK ,whose encoding is like this

<?xml version="1.0" encoding="UTF-8"?> It works fine, I can parse the values.

is xml parsing failing due encoding not being UTF-8,it is utf-8 ??

How should I deal with this. I have done google and am new to XML parsing. This is my first parsing which I am trying to create. Please let me know the way.

updated with code :

public String getXmlFromUrl(String url) {

    String xml = null;

    try {            
        // defaultHttpClient
        HttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);           
        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity(); 
        xml = EntityUtils.toString(httpEntity);
        System.out.println("response -- " + xml);

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    // return XML
    return xml;
}

解决方案

Straight away it looks like the problem is with Encoding of XML in your response.

URL url = new URL("http://myurl.com");
InputSource is = new InputSource(url.openStream());
is.setEncoding("ISO-8859-1"); // Also Try UTF-8 or UTF-16
BufferedReader br = new BufferedReader(new InputStreamReader(is.getByteStream()));
String line,str;
while((line=br.readLine())!=null)
{
      str = str + line;
}
Log.i(TAG,str);
