jsoup: Java HTML Parser

 jsoup: Java HTML Parser

• jsoup is a Java library for working with real-world HTML. It provides a very convenient API for extracting and manipulating data, using the best of DOM, CSS, and jquery-like methods.
  
  HTML 문서를 읽어들인 후에 그 문서를 DOM 객체로 변환
  Document doc = Jsoup.parse(html);

  jsoup implements the WHATWG HTML5 specification, and parses HTML to the same DOM as modern browsers do.

  • scrape and parse HTML from a URL, file, or string
  • find and extract data, using DOM traversal or CSS selectors
  • manipulate the HTML elements, attributes, and text
  • clean user-submitted content against a safe white-list, to prevent XSS attacks
  • output tidy HTML

  jsoup is designed to deal with all varieties of HTML found in the wild; from pristine and validating, to invalid tag-soup; jsoup will create a sensible parse tree.
