Decided to write a simple television program using JSoup . The task is more than boring, but for me a new hell before the parser did not work. I ask you to help not in writing the code, but how to work with a parser, read articles, but they only tell about the headlines, etc., but how, for example, resign a schedule from the first channel to Page . And maybe you think that JSUP Full Larger Advise another.

Well, what’s the problem?
- Download the document .
- Snapsorize to the item containing the program.
- in the same way Find the necessary data items.
which HTML attributes you need is installed attentive reading the source site that you are going to steal.
On the site there is even a the simplest example (without navigation, just all links).

There are 2 types of HTML / XML Parcers:
- SAX Parser – Parsit in streaming mode, the input is fed by HTML / XML, in certain places it is triggered by the so-called. Handlers, that is, the interceptors who say “now the parser came across such an element.” In Handler, a proper code inserts its code and makes its business
- Dom Parser – the whole source is shoved, we get a tree at the exit – sometimes quite complicated.
jsoup is a type of Dom Parser, so the whole question is to properly be proposed in the tree received after the parsing – or expressing the model DOM model in nodes. This is described by the JSOP API documentation in the ORG.JSUP.NODES package.
At the same way, it will be worth reading about DOM it will immediately send the brains in the right direction.
Good luck.
