Java - Extract html information from string

All of the guides out there tell me on how to remove the HTML tags from the text to extract the text between them. What I am after is the extraction of the data that is within the HTML tags.

e.g.

If i have a string:

 "<FONT SIZE="5">Hello World</FONT>"

I want to get the font size information to update other variables. How do I go about this?

I've used jsoup several times for this purpose. It's a lenient HTML parser. Beware trying to parse it as "standard" XML as XML-parsing is strict by nature and will fail if the page does not conform to XML markup specs (which few HTML pages do).

You can use a library like jerichoHTML wich enables you to search for HTML tags as well as their attributes or you build some DOM on you own.

You go about this by using one of the available Java libraries for HTML parsing, like TagSoup.

Take a look at this: http://en.wikipedia.org/wiki/Java_API_for_XML_Processing If you parse the HTML you should be able to extract the values from the DOM tree.
