Regular Expression problem

[cdecarlo]

Hey,

I'm new with regex's as well but here is my idea. Since you don't know
which attribute will come first why don't structure your regex like
this

(first off, I'll assume that \s == ' ', actually now that I think of
it, isn't \s any whitespace character? anyways \s == ' ' for now)

'<link\s*((\s*attribute1\s*)|(\s*attribute2\s*)|(\s*attribute3\s*))+>'

I think that should just about do it.

Hope this helped,

Colin
