Yes, but it is eval, unfortunately. eval is dangerous; Never use it with user input!

s[/][\\/]g for $lhs, $rhs;
eval "s/$lhs/$rhs/";

Alternatively,

$rhs =~ s["][\\"]g;
$rhs = q["$rhs"];
s/$lhs/eval $rhs/e;

Probably you should reconsider if you really do want this.

Also, parsing XML with regexes is bad, .* is bad, and $ doesn't do what you think,

Perl 6 changes:

• The new regexes are called rules.
• The e (eval) flag for s/// disappeared. Instead of it, use the generic expression interpolation syntax.
• Expressions are interpolated with {}, so s/foo/bar/e is now s/foo/{bar}/.
• Flags are written in front instead of at the end. s/foo/bar/g is now s:g/foo/bar/.
• $ really matches the end of the string. For the end of the line, use $$.
• Perhaps using XML with rules will be more socially accepted, as there can be an XML compliant grammar.
• The new special variable $/ holds all captures, named and unnamed.
• $1 and friends begin with $0, and are shortcuts for $/[0], $/[1], $/[2], ....
• Capture variables are immediately active, and a backreference is now spelled <$0>.
• You still have to use eval for what you ask for here.
• The s flag disappeared, . always matches any character, including \n. To match any character except \n, use \N.
