A collection of powerful Twig filters for modifying HTML. Here are some of the things Retcon can do:

• Add attributes (e.g. class="foobar", style="color:red;" or data-foo) to any selector (e.g. p, img, span.foobar etc)
• Remove attributes for any given selector (e.g. remove style attribute for all p tags)
• Append to attributes
• Remove DOM nodes by selector (e.g. remove all span tags)
• Remove everything but given selectors (e.g. remove everything except img tags)
• Transform inline images (it even uses Imager, if installed)
• Add srcset or lazyloading to inline images
• Inject strings or HTML content
• Change tag names for given selectors (e.g. change all occurrences of <p> to <span>)

...and much more! Check out the Wiki for complete docs and examples.

Update: Retcon is now using Symfony's DomCrawler component for much more powerful selectors. It's basically jQuery now!
