Note however that no information has been selected for retrieval. In Perl, this means that if the query is enclosed in double quotes, this dollar sign must be escaped. This is another area where this module differs from the specification. The regular expesssion ability as defined in the specification only allows for a subset of the ability available in a Perl regular expression. With this module, the full range of regular expression syntax has been made available.
All non tag matched are case insensitive.
Now lets say that besides matching the TYPE, we also wanted to grab the value. This clause is not required. This can be any URI that is supported by LWP, or it can be a single file name enclosed in quotes. In later versions of this module there will be support for multiple files, directories. This construct will be repeated for every match found and returned as a single string.
