Exquery

Turns the text into a flat list of tokens. You probably want to use Exquery.tree/1 if you actually want to find elements in the HTML tree.

Examples

iex> Exquery.tokenize("<div><input></div>")
[{:open_tag, "div", []}, {:self_closing, "input", []}, {:close_tag, "div", []}]

iex> Exquery.tokenize(";_;")
[{:text, ";_;", []}]

Turns the text into a tree which can then be queried by the functions in the Exquery.Query module.

A tree is a list of tuples where the first element of the tuple is an HTML element, and the second element of the tuple is its children.

An HTML is the element name (:tag, :script, :text, etc), its contents, and a list of its attributes

Examples

#h1 is a child of div, and "hi" is a child of h1
iex> Exquery.tree("<div><h1>hi</h1></div>")
[{{:tag, "div", []}, [{{:tag, "h1", []}, [{:text, "hi", []}]}]}]

#:text elements can't have children
iex> Exquery.tree("something")
[{:text, "something", []}]

#This has no children
iex> Exquery.tree("<div></div>")
[{{:tag, "div", []}, []}]
