FUNCTIONS

extract_main_html

extract_main_html takes HTML content, and uses the Readability algorithm to detect the main body of the page, usually skipping headers, footers, navigation, etc.

The first argument is either an HTML string, or an HTML::TreeBuilder tree. (If passed a tree, the tree will be modified and destroyed.)

Remaining arguments are optional and represent key/value options. The available options are:

output_type

This determines what format to return data in. If not specified then xhtml format will be used. Valid formats are:

xhtml
html
tree

If tree is selected, then an HTML::Element object will be returned instead of a string.

If the HTML's main content is found, it's returned in the chosen output format. The returned HTML/XHTML will not look like what you put in. (Source formatting, e.g. indentation, will be removed.)

If a most relevant block of content is not found, extract_main_html returns undef.
