Performs transformations of HTML by wrapping around libxml2 and working around its countless bugs.
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\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 $formatter->filterContent(); // Direct DomDocument manipulations are possible $formatter->getDoc()->createElement( 'p', 'Appended paragraph' ); // Get resulting HTML $processedHtml = $formatter->getText();
