jsoup.Parse在iframe元素上不起作用

Question

I am trying to parse HTML file. The HTML includes iframe contents. But jsoup.parse() is working on all elements excepts iframe elements. Can anyone help me on this. For example:

String html = "<iframe src='demo_iframe.htm' height='200' width='300'></iframe>";
String doc = Jsoup.parse(html).text();
System.out.println(doc);

The output should look like:

demo_iframe.htm height:200 width:200

You have to select iframe element. Here is solution

String html = "<iframe src='demo_iframe.htm' height='200' width='300'></iframe>";
    Document doc = Jsoup.parse(html);
    Element iframe = doc.select("iframe").first();
    String iframeSrc = iframe.attr("src");
    String height = iframe.attr("height");
    String width = iframe.attr("width");
    System.out.println(iframeSrc + " height:" + height + " width:" + width);

Use selector-syntax to find elements
