Regular expression that ignores HTML entities

I need a regular expression in javascript which does the following.

Those instances of a which are not the part of an HTML entity, should be replaced with w.

Ex: 

abc should change to wbc

aabacaa should change to wwbwcww

&abcaa& should change to &wbcww&

and so on.

I am using JavaScript.

Any help is appreciated.

Solution

  • Try this:

    "&abcaa&".replace(/&[^;]+;|a/g, function($0) {
    return $0 === "a" ? "w" : $0;
})
