Default matches without repeated items

Hi,

Please anyone helps me how to use regex for matching items without duplication. Is it can be done? I searched the internet all day, and still cannot find any useful information.

my file:
<bookmark filepath="66286_01.pdf" />
<bookmark filepath="66286_02.pdf" />
<bookmark filepath="66286_01.pdf" />

I tried: \w+\.pdf

The result:
66286_01.pdf
66286_02.pdf
66286_01.pdf

I don't want the second 66286_01.pdf.

Please help.
Thank you very much.
