Jsoup example to read data form different html's page (or) websites? should be reusable to any website

I have a requirement to read data from different websites using Jsoup html parser (Ex: name, city, state, zip etc.). I can able to read the data from one website. but the problem is my code should be reusable to other websites. but in the other website elements and their position is different to first website. How to achieve this. please suggest any pattern or any examples. thanks.

I'll get this straight for you, there is NO WAY to achieve a general parser to scrape all websites. I've worked at a company where I had to scrape 30 websites. And I literally had to write one for every website.
You can however create general utility classes that helps you to process the data you've parsed.

android get news article content

I am creating a news app and have the url to the site of the articles e.g http://www.bbc.co.uk/news/technology-33379571 and I need a way to extract the content from the article.
I have tried jsoup but that gives all the html tags and there is one <main-article-body> but that gives the link to the article which I am trying to extract. I know boilerpipe does it exactly but that doesnt work with android, I am really stuck with this problem.
Any help will be much much appreciated

I have worked on few data extraction applications in.Net (c#) and have used regular expressions to extract content from news website.
The basic idea is to first extract all a href links (as needed) and then fetching details content by making web request. Finally using regular expressions to extract news body data.
Note: A problem with this process is that you will need to change your regular expressions when data source site changes.

Hw dynamic HTML parser works

lucene searching

Dear StackOverFlow Developers I want a help from you . I am stuck in Apache lucene to use in java swing application . The problem is so complex that even i m confused how should i ask it.
Please try to understand what is my actual requirement.
The case is the simple i have to give html files so that client can access them in swing application and for searching facility i decided to use apache lucene indexing. this is providing me the search facility but now i want to display the html file data which has matched the search criteria . In java API i m using swing for it and JEditorPane is the control in which i have to display the contents of html file . Please suggest me how should i index the html files and how should i get the content of html files back from lucene index.
the html files not only having text only but also they are having links , images etc.
thanks in advance hoping help from you
regards

In one of our projects where we employed Lucene for full text indexing & search, we handled HTML files as follows:
Stored the HTML document as is on disk (you can store in the DB as well).
Using Jericho HTMLParser's HTML->Text converter, we extracted the text, links etc., out of the HTML documents.
The lucene document has attributes that stored the metadata about the HTML file apart from the text content in the HTML in tokenized format.
Used StandardAnalyzer to keep certain tokens like email, website links as is during the tokenization process before indexing.
Upon searching the index, the hits returned contained the metadata of the HTML files that matched the criteria. So, we were able to identify the HTML content to be displayed for a given search result.
HTH.

Convert HTML page into MS word using java or any API

I want to convert a HTML page into MS word. I want to know what API's will be helpful and also if there is any other option to do the same.
The entire page is to be converted into .doc (eg. If there is a table in the html page, a similar table must be created in the word doc) .
Apache POI does not provide an option to format the word document as in the HTML page.
I need something that can give me a completely formatted word document.
Some of the things that i seek are JSOUP, docx4j, jasper reports, and JOD Convertor.
I tried parsing the HTML page using JSOUP and I get the contents of
the page in my java program. Now I need to pass these contents to a
doc/docx file. Can docx4j be helpful to get a formatted docx file?
Please help.
Thank you.

I would go with Ashwini Raman's suggestion. It wont work with every scenario. In the case of a complex HTML document with many images and stuff word will not do a good job. But for most cases it should be fine. Otherwise, there is a complex task ahead of you. You will have to parse your HTML document using the jsoup library for example and then use the docx4j library to create your workd document.
Links to both are here:
http://www.docx4java.org/trac/docx4j
http://jsoup.org/
When you are doing it also, the formatting might be iffy.
To answer your original question, no there is no ready made library that does what you are expecting. At least I havent come across any.

I found a way round to do the same. First I need to get the parsed objects using JSOUP and pass these to a document template. I am now looking for the options that can provide me creating easy templates and creating the document dynamically.
I have asked another question regarding the same.
