When Emacs is compiled with libxml2 support, the following functions are available to parse HTML or XML text into Lisp object trees.
This function parses the text between start and end as HTML, and returns a list representing the HTML parse tree. It attempts to handle “real world” HTML by robustly coping with syntax mistakes.
The optional argument base-url, if non-
nil, should be a string specifying the base URL for relative URLs occurring in links.
In the parse tree, each HTML node is represented by a list in which the first element is a symbol representing the node name, the second element is an alist of node attributes, and the remaining elements are the subnodes.
The following example demonstrates this. Given this (malformed) HTML document:<html><head></head><body width=101><div class=thing>Foo<div>Yes
A call to
libxml-parse-html-regionreturns this:(html () (head ()) (body ((width . "101")) (div ((class . "thing")) "Foo" (div () "Yes"))))
