jsoup: Java HTML Parser

jsoup is a Java library for working with real-world HTML. It provides a very convenient API for fetching URLs and extracting and manipulating data, using the best of HTML5 DOM methods and CSS selectors.

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-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.

See jsoup.org for downloads and the full API documentation.

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:

Document doc = Jsoup.connect("https://en.wikipedia.org/").get();
log(doc.title());
Elements newsHeadlines = doc.select("#mp-itn b a");
for (Element headline : newsHeadlines) {
  log("%s\n\t%s", 
    headline.attr("title"), headline.absUrl("href"));
}
