Question

我发出了get请求并将响应存储在字符串response中：

HttpClient client = new DefaultHttpClient(); 
String getURL = "some_url_with_param_values";
HttpGet get = new HttpGet(getURL);
HttpResponse responseGet = client.execute(get);  
HttpEntity resEntityGet = responseGet.getEntity();   
String response = EntityUtils.toString(resEntityGet);

但我只对具有类名<div>的{{1}}感兴趣。所以，我这样做了：

<div class="product-data">

不幸的是，它没有用。任何帮助将不胜感激。

<小时/> 我的响应字符串基本上是一个html页面。

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder;
InputSource is;
builder = factory.newDocumentBuilder();
is = new InputSource(new StringReader(xml));
Document doc = builder.parse(is);
NodeList list = doc.getElementsByTagName("product-data"); //I even tried: (div class="product-data)
String test = list.item(0).getNodeValue(); //Just to test it

我认为你应该尝试使用getElementsByClassName('product-data')

如果这不起作用，您可以随时查看Jsoup，它提供了一个库，可以轻松地从网页中提取Html元素

DefaultHttpClient client = new DefaultHttpClient();
HttpGet get = new HttpGet(url.toURI());
HttpResponse resp = client.execute(get);

String content = EntityUtils.toString(resp.getEntity());
Document doc = Jsoup.parse(content);
Elements ele = doc.select("div.classname");

此示例执行Http GET，然后使用类“classname”提取所有Div元素，然后您可以使用
