HtmlFormatter Documentation

HtmlFormatter is a library spun off MediaWiki that allows you to load HTML into DomDocument, perform manipulations on it, and then return a HTML string.


use HtmlFormatter;
// Load HTML that already has doctype and stuff
$formatter = new HtmlFormatter( $html );
// ...or one that doesn't have it
$formatter = new HtmlFormatter( HtmlFormatter::wrapHTML( $html ) );
// Add rules to remove some stuff
$formatter->remove( 'img' );
$formatter->remove( [ '.some_css_class', '#some_id', 'div.some_other_class' ] );
// Only the above syntax is supported, not full CSS/jQuery selectors
// These tags get replaced with their inner HTML,
// e.g. <tag>foo</tag> --> foo
// Only tag names are supported here
$formatter->flatten( 'span' );
$formatter->flatten( [ 'code', 'pre' ] );
// Actually perform the removals
// Direct DomDocument manipulations are possible
$formatter->getDoc()->createElement( 'p', 'Appended paragraph' );
// Get resulting HTML
$processedHtml = $formatter->getText();
