Looking for a nice CGI-related string representation module

I'm writing some CGI scripts that deal with user input and databases,
and I was wondering if anyone could recommend any good string handling
modules designed for use with CGI applications. I'm looking for
something that can efficiently translate between the different
representations of the same string.
Examples of different representations might include what the user typed
in verses the escaped version for a SQL string, verses a differently
escaped version for output as part of an HTML page, verses an integer
representation if possible, and so on. Being able to naturally add
representation modes would be a bonus. Maybe the user types in a
wiki-like representation, such as using *'s for bulleted lists, and the
module can translate it to an HTML format or SQL format on the fly, and
I'd like to be able to create some type of string object that would act
similar to a python string, but also contain internal information about
the sort of string it is so the conversions can be idempotent. eg. If I
ask for an HTML-escaped version of something that already knows it's
HTML-escaped, I want it to just return itself rather than something
doubly-escaped... unless I told it that I wanted it doubly-escaped for
some reason. I'm not sure how it would act for things like appending
different representations of strings together, but hopefully it'd do
something intelligent. :)
I guess I'm looking for something that handles strings in the same way
that mxDateTime handles dates and timezones and so on. :)
I'd also like it to be able to run input through filters to do basic
things like checking for HTML tags, maybe allowing some through and
blocking others, and so on.
I've written my own very primitive module that does some of this in a
not-too-tidy way, and I could improve what I have as I need to. On the
other hand if there's already a well established module out there, I'd
prefer to use it instead. Having searched around a bit though, I can't
seem to find anything.
If anyone can point me to any modules that can do this sort of string
manipulation and filtering, I'd very much appreciate it.
Thanks for any help.
