JavaScript中的递归正则表达式模式

Question

I know it's going to be a VERY obvious answer, but I can't find anything on how to do this.

I'm trying to unescape < and > within an HTML string

My test output string is essentially:

```php
>h2<Heading2>/h2<
```

`>h2<Heading2>/h2<`

>h2<Heading2>/h2<

So in this example we have Github flavoured Markdown, a regular code markdown snippet, and then raw text all with the same HTML tag. I want to unescape the raw tag (the third one) to actually become a link. The ideal output would be something like this.

```php
>h2<Heading2>/h2<
```

`>h2<Heading2>/h2<`

<h2>Heading2</h2>

I'm getting stuck at getting multiple > in the same line.

Current regex:

/(?:.*?(>))/

This will get the first entry.

/(?:.*?(>))/g

This one gets the second entry. I want it to be able to get EVERY entry. Then, it's just a matter of throwing the tick pieces.

/(?:```|`)(?:.*?(>)).*?(?:```|`)/gs

If you're intending on using a regular expression for this task, you can consider the following:

var r = s.replace(/((`(?:``)?)[^`]*\2)|&gt;/g, '$1<')
         .replace(/((`(?:``)?)[^`]*\2)|&lt;/g, '$1>')
         .replace(/`[<>]+/g, '`');
