regex

I have text with file names scattered throughout. The filenames appear in the text like this:

|test.txt|
|usr01.txt|
|usr02.txt|
|foo.txt|

I want to match the filenames that don't start with usr. I came up with (?<=\|).*\.txt(?=\|) to match the filenames, but it doesn't exclude the ones starting with usr. Is this possible with regular expressions?

I am writing a tool to help students learn regular expressions. I will probably be writing it in Java. The idea is this: the student types in a regular expression and the tool shows which parts of a text will get matched by the regex. Simple enough.

I need to be able to check for a pattern with | in them. For example an expression like d*|*t should return true for a string like "dtest|test".
