为什么我只得到 <?xml version=“1.0” standalone=“no”?> 什么时候要求xml文件？ 安卓系统

Question

I am using this method to get xml file from a remote server, I use another parser class to parse it, and it got parsed successfully. However, when i use Log.d("get xml", xml) to check the content of the xml file, it only shows <?xml version="1.0" standalone="no"?> in logCat. Why?

public String getXmlFromUrl(String url) {
    String xml = null;

    try {
        // defaultHttpClient

        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);
        if(httpPost != null){
            Log.d("httpPost", "httpPost not null");
        }
        HttpResponse httpResponse = httpClient.execute(httpPost);
        if(httpResponse != null){
            Log.d("httpResponse", "httpResponse not null");
        }
        HttpEntity httpEntity = httpResponse.getEntity();
        xml = EntityUtils.toString(httpEntity);

    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    // return XML
    Log.d("get xml", xml);
    if(xml!=null){
        Log.d("get http client", "get http client not null");
    }
    return xml;
}

I think the problem wasn't the request but the output in the LogCat. Logging every line separately obtained the desired full response!.

So check this by applying breakpoint in debug mode. Might its help to you.
