in reply to Passing values to external packages

The difference is the quotes around W3C::STRING. It's a function call in your first snippet, and a string literal in the second.

By the way, using <c>...</c> around code to post is an easy way to handle posting code on PerlMonks. It saves you from putting all the line breaks and escaping characters such as <.

    That makes complete sense! Thanks for the fast response and advice on posting tags.
    It gets a bit more complicated now because I need to append the value of a variable coming from an XML file to part of the function call value as follows: 
    #...
$value = $verify->{content}; #string value pulled from XML file ($valu
+e = STRING)
$wc3_type = W3C::.$value #will not work

    How can I append the scalar $value to the function call without it being a quoted value?

    TIA AGAIN!

      You could use a lookup table. 
      my %validators = (
   string => W3C::STRING,
   ...
);

my $type = $verify->{content}; 
my $validator = $validators{lc($type)};
if (!defined($validator) || !dvalid($search, $validator)) {
   die
}

    Well - more code than I had hope to write for this, but it works wonderfully. Thanks for the quick and helpful responses.
