问题描述
我试图解析从这个链接,它的XML编码是这样的
< XML版本=1.0编码=UTF-8>
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
< XML版本=1.0编码=UTF-8>
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;
}
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;
}
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);
