Is this possible? Using only an one liner JavaScript regexp

Question

How can I convert this into an one-liner JavaScript regex?

html.replace(/src="(.*?)"/gi, function($1)
{  return $1.replace(/(abc.*?)\/abc/gi, "abc");
});

The above code block should be self-explanatory of what I'm trying to accomplish, but I'll elaborate.

What I'm trying to accomplish is replace all matches of this regex /src="(.*?)"/ which contains the substring: abc[random_characters]/abc to just abc. And so for example

src="abc[random_characters]/abc[random_characters]" => src="abc[random_characters]"

Edit: One-liner without the anonymous function call or callback.

Edit: Solution

html.replace(/src="abc(?:.*?)\/(abc[^"]+)"/gi, "src=\"$1\"");

Answer 1

Use backreference:

html.replace(/src="(abc[^\/]*\/?)+"/gi, 'src="$1"');

• (abc[^\\/]*\\/?) — matches abc + random characters (except for / );

• "$1" — a backreference to the captured group.

However, I'm not quite sure it satisfies you requirements. Your description of a problem is a little bit inconsistent.
