    I presume what you want is to determine what's between the include tags, ignoring the leading '$CONFIGURATION_PATH$/'.

    my ($desired) = $original =~ m{^<include>\$CONFIGURATION_PATH\$/(.*)</include>$};

    Update: Removed stray slash in regexp.

    Is this truly in XML?
    Will there be multiple include pairs (elements)?

    Jst for fun and since I know compuers can be a wee bit picky, your string "USERs/User_01/user_01.config" will never be fouind in the string "<include>$CONFIGURATION_PATH$/USERs/user_01/user_01.config</include>"

    User_01 and user_01 do not match due to case difference.

    use uc() on both sides of the strnig and attempt a compare.
