jsoup:一个强大的java html解析工具

2015-09-05

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.

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

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

Example

Fetch the Wikipedia homepage, parse it to a DOM, and select the headlines from the In the news section into a list of Elements (online sample):

Document doc = Jsoup.connect("http://en.wikipedia.org/").get();
Elements newsHeadlines = doc.select("#mp-itn b a");
