TransformerInnerHTML.js hangs browser in raw image data "img" tag (Trac #1596) #1596

Closed sleemanj closed 3 years ago

I am using Xinha to allow rich text editing in my web application. When the editor component gets an "img" tag with raw base64 encoded image data in it (see template file for html img data that cause the problem) the TransformerInnerHTML.js script hangs on the "cleanHTML" method. Probably the regular expression match and replace takes too long for these type of use cases. Problem is reproducible in Xinha 0.95. I haven't tried other Xinha versions.

Probably time has marched on since this was reported and processor speed has caught up.

Also, putting that much Data URI in a page is a bad idea generally, and DOMWalk will be faster.
