Hello,

currently I have a problem with reading a string from command line and using it in a regular expression.

What I exactly want to do is a bit hard to explain what could be the problem that I cannot find anything with the search function here.

I want to read something like "foo\x32\x33\x34bar" via Term::ReadLine and convert it so as if I had entered directy in the code like my $foo = "foo\x32\x33\x34bar";

To make it a bit cleared this is what I currently get:
66 6F 6F 5C 78 33 32 5C 78 33 33 5C 78 33 34 62 61 72  |  foo\x32\x33\x34bar

But what I want is:
66 6F 6F 32 33 34 62 61 72  |  foo234bar

How can I pack/unpack/convert the string to handle this?

Any ideas will be welcomed!

Thanks in advance :)
