为Android应用程序刮取此HTML的最佳方法是什么？

Question

What is the best way to scrape the below HTML from a web page? I want to pull out Apple, Orange and Grape and put them into a dropdown menu in my Android app. Should I use Jsoup for this, and if so, what would be the best way to do it? Should I use Regex instead?

<select name="fruit" id="fruit" >
<option value="APPLE">Apple</option>
<option value="ORANGE">Orange</option>
<option value="GRAPE">Grape</option>
</select>

Answer 1

Depends, but I'd go with an XML/HTML parser. Don't use regex .

Example with jsoup :

Document doc = Jsoup.connect(someUrl).get();
Elements options = doc.select("select#fruit option");

More on jsoup selector syntax .

Best way?

I would go with either the built-in DOM parser or SAX parser . If you're going to be parsing a large document, SAX is faster. If the document is small, then there's not much difference. More on SAX vs DOM .

Answer 2

For HTML parsing you can use jsoup. The usage is very easy and the API is great.

http://jsoup.org/

For me it worked great!

EDIT: too slow :D skyuzo's post is great :)

WebView is your friend:

It let's you grab html as a browser, and then you can do stuff with it. Take notice that it doensn't take into account javascript, so I hope that's plain html you have therem not some ajax fetched or js generated code :)
