Perhaps you want just

<pre><code>print "something\n" if exists $HoH{regexp}
</code></pre>

or maybe

<pre><code>print "something\n" if grep /regexp/, keys %HoH
</code></pre>

but if neither of these are correct then you need to explain better what you need, and give some examples

blocks|key|3694606|text|这是在文档中描述的，我不知道具体问题是什么，但是智能匹配操作符在引用数组和散列时工作得更好。所以你可能会更幸运|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3694607|/$reg/+~~+\%25Hoh|code-block|syntax|javascript|3694608|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

This is under documented, and I don't grok exactly what the issue is, but the smart match operator works better with references to arrays and hashes. So you may have better luck with

<pre><code>/$reg/ ~~ \%Hoh
</code></pre>

blocks|key|3694649|text|SmartMatch目前是复杂的、笨重的和令人惊讶的。别用它，至少现在不用。perl的主要开发人员谈论要么大大简化它，要么完全删除它。无论哪种方式，它都不会做你要求它在未来做的事情，所以现在不要依赖它去做。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3694650|更明确地说出你想要的是更好的。|3694651|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

SmartMatch is currently complicated, unwieldy and surprising. Don't use it, at least not now. There's talk by the main developers of perl to either greatly simplify it or remove it completely. Either way it won't do what you're asking it to do in the future, so don't rely on it doing that now.

Being more explicit about what you want is better anyway.

blocks|key|3718310|text|很可能，您的bug在这里：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3718311|foreach+$characters+(keys+%25{$HoH{$cluster}})+{|code-block|syntax|javascript|3718312|应改为|3718313|foreach+$characters+(keys+%25{$HoH{$value}})+{|3718314|。可能吧。|3718315|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Most likely, your bug is here:

<pre><code>foreach $characters (keys %{$HoH{$cluster}}) {
</code></pre>

which should read

<pre><code>foreach $characters (keys %{$HoH{$value}}) {
</code></pre>

. Probably.

I want to match keys of a hash of hash with regexp .

<pre><code>$line=" Cluster(A,B):A(T) M(S)";
$reg="Cluster";
my ( $cluster, $characters ) = split (/:/,$line);
$HoH{$cluster}={split /[( )]+/,$characters } ;
foreach $value(keys %HoH){
 foreach $characters (keys %{$HoH{$cluster}}){
 print "$value:$characters\n" if /$reg/ ~~ %HoH;
 }
}
</code></pre>

now Output is :

Cluster(A,B):A

Cluster(A,B):M

This code is works fine with this sample data,but not with real data!! my data is more complicated but the structure is the same I was wondering if there is some other ways to do this
