Strip All HTML Tags Except Links

Strip all HTML tags except links

<(?!\/?a(?=>|\s.*>))\/?.*?>

Try this. Had something similar for p tags. Worked for them so don't see why not. Uses negative lookahead to check that it doesn't match a (prefixed with an optional / character) where (using positive lookahead) a (with optional / prefix) is followed by a > or a space, stuff and then >. This then matches up until the next > character. Put this in a subst with

s/<(?!\/?a(?=>|\s.*>))\/?.*?>//g;

This should leave only the opening and closing a tags

And the JavaScript demo:

var input = 'b<body>b a<a>a h1<h1>h1 p<p>p p</p>p img<img />img';

var output = input.replace(/(<\/?(?:a|p|img)[^>]*>)|<[^>]+>/ig, '$1');

console.log(output);

this.html(this.html().replace(/<\/?([b-z]+)[^>]*>/gi, function(match, tag) { 
  return (tag === "a") ? match : "";
