Download and extract data from HTML/XML pages as well as JSON APIs. More information: <https://www.videlibri.de/xidel.html>.

• Print all URLs found by a Google search:
  xidel https://www.google.com/search?q=test --extract "//a/extract(@href, 'url[?]q=([^&]+)&', 1)[. != '']"
• Print the title of all pages found by a Google search and download them:
  xidel https://www.google.com/search?q=test --follow "//a/extract(@href, 'url[?]q=([^&]+)&', 1)[. != '']" --extract //title --download '{$host}/'
• Follow all links on a page and print the titles, with XPath:
  xidel https://example.org --follow //a --extract //title
• Follow all links on a page and print the titles, with CSS selectors:
  xidel https://example.org --follow "css('a')" --css title
• Follow all links on a page and print the titles, with pattern matching:
  xidel https://example.org --follow "<a>{.}</a>*" --extract "<title>{.}</title>"
• Read the pattern from example.xml (which will also check if the element containing "ood" is there, and fail otherwise):
  xidel path/to/example.xml --extract "<x><foo>ood</foo><bar>{.}</bar></x>"
• Print all newest Stack Overflow questions with title and URL using pattern matching on their RSS feed:
  xidel http://stackoverflow.com/feeds --extract "<entry><title>{title:=.}</title><link>{uri:=@href}</link></entry>+"
• Check for unread Reddit mail, Webscraping, combining CSS, XPath, JSONiq, and automatically form evaluation:
  xidel https://reddit.com --follow "form(css('form.login-form')[1], {'user': '$your_username', 'passwd': '$your_password'})" --extract "css('#mail')/@title"
