HELP with whitelisting certain target of Element Hiding rule

[byzod]

A filter in subscription list hid both the download link (what I want to show) and the advertisement image (what I want to hide), I tried to write a whitelist for the download link but failed.
Fortunately the list update yesterday and fixed the problem.

But I still wonder how can I write such whitelist for it, is it possible?
Considering page below

Sample page of sample site http://A.us:

Code: Select all

<span class="dl">
    <!-- The <a> below is a download link -->
    <a rel="nofollow" target="_blank" href="https://A.us/go/?url=http://pan.baidu.com/s/1boA1T1P">
        Download Link
    </a>
</span>
<div class="buyaoa">
    <!-- The <a> below is an ad. -->
    <a href="https://A.us/go/?url=adbottom" target="_blank" rel="nofollow">
        <img src="https://www.not-an-ad-domain.cn/but-an-ad.jpg">
    </a>
    <div class="comments">
        ...comment list should not be touched...
    </div>
</div>

The original hide rule from subscription list: A.us##a[href*="/go/"] ...(1.1)
It hid both `.dl>a` and `.buyaoa>a`.

I wrote some whitelist rules but none of them works
A.us#@#.dl > a[href*="/go/"] : no effect ...(2.1)
A.us#@#.dl > a[rel=nofollow] : no effect ...(2.2)


Question I want to ask:
1. Why rule (2.1) and (2.2) is not working?
2. How to write a rule (2.3) that can whitelist `.dl>a` while still block `.buyaoa>a` without disabling the subscription rule (1.1)?

[mapx]

you could try (whitelisting the same rule and then writing a new one for hiding)
A.us#@#a[href*="/go/"]
A.us##a[href*="/go/?url=adbottom"]

I know that so I mentioned

How to write a rule (2.3) that can whitelist `.dl>a` while still block `.buyaoa>a` without disabling the subscription rule (1.1)

Actually what I really concerning is why rule (2.1) (2.2) fails because I think the CSS selector is correct and have higher priority than subscription one

[mapx]

You have no higher priority. You have first to disable (whitelisting) the previous rule.

You have no higher priority. You have first to disable (whitelisting) the previous rule.

So it's impossible to whitelist `B` if another rule already hide `A`, `B` and `C`?
Then what's the point of a `whitelist` since it can't really whitelist anything?

[mapx]

Again: You have to whitelist exactly the same previous rule. Then add whatever other hiding rule you want.
