Re^2: Elegant way to escape a string in a regex

Thanks. I did not know the last one you gave (s{...}'//div[@id="abc"]'). I should not have used \Q\E then. I did use it in case there were things like $1 in the replacement string. But q{//div=[@id="$1"]} gives no problem and escapes that too.

So, just to confirm, q{} is absolutely safe for providing a substitution string which nothing in it will be interpreted by the regex (e.g. $1) or by perl (e.g @id): all contents of q{} will be literal, nothing interpreted.

In single-quoted string literals (e.g. «`q{}`»), only «`\`» and the delimiter(s) (i.e. «`{`» and «`}`» when using «`q{}`») are significant. You may need to escape instances of the former, while instances of the latter needs to be escaped or balanced. Finally, you must not escape anything except the aforementioned characters.
