A Good JAVA library to parse HTML, POST AND GET HTTP suitable for Mobile?

Question

Hello,

I'm making an android client for a web site. my app have to go through the website, parse HTML, post some forms, send HTTP requests etc.

What library covering all this stuff you recommand me to use ?

thanks.

Answer 1

Using HttpURLConnection make a server call . Open the connection get the stream.

For parsing HTML tags you can go with XMLPullParser available in Android. You should be able to read HTML tags from it.

Answer 2

HttpClient should be good. And parsing can be done using XMLPullParser

Here is another approach to Using XPATH and HTML Cleaner to parse HTML / XML

I also read here that Jericho HTML Parser works well on Android. it works very efficiently in Android, and has a pretty comprehensive API. There are examples on the site, but to give you an idea of the syntax:

Source source = new Source(new URL("www.google.co.uk")); 
List<Element> linkElements = source.getAllElements(HTMLElementName.A); 
for (Element linkElement : linkElements) { 
        String href = linkElement.getAttributeValue("href"); 
        if (href != null) { 
                System.out.println(href); 
        } 
} 

To add third-party libraries into an Android project, you don't link them like you would in Java - you have to extract them into your project. See here:
