Xidel is a command line tool to download and extract data from HTML/XML pages as well as JSON APIs.

It supports:

• CSS 3 Selectors: to extract elements unchanged
• XPath 3.0: to extract values and calculate things with them.
• XQuery 3.0: to create new documents from the extracted values and to build Turing-complete scripts.
• Pattern matching: to extract several expressions in an easy way using an annotated version of the input page for pattern-matching.
