Subject: gsub html sanitizer

I'm new to Ruby and a bit confused about how gsub works. I've read the
documentation, searched ruby-forum, and tried numerous google searches,
but can't seem to figure out how to do something that should be simple.

This is just an example, but say I have a string "apple cat flower". I'd
like to replace all instances of the pattern "apple" with the string
"fruit," "cat" with the string "animal," and "flower" with the string
"plant." Meaning I have more than 1 pattern to replace, each with a
specific string to replace.

So I want "apple cat flower" to be converted into "fruit animal plant".

I hope this isn't too confusing. Help is appreciated :)
