Can I use two “regular expression” conditions??

[scryed]

Hi guys..
i am interested in examdiff pro, but i have important question.
Can I use two “regular expression” conditions on the same line? and how?
for example I have:
txt file#1: "hi line 3 see you later 44"
txt file#2: "hi line 7 see you,, later 55"

i don't want to include in the comparing process these two regular expressions line [0-9]* and later [0-9]*

in other words i want to see the difference is ",,"

You can use the vertical bar character ("|") to denote OR relationship between individual regular expressions.
