Hi,

i need the help of an expert Regular Expression guy :)

i just need to confirm the below regular expressions:

^111_[0-9]+$ -> AS111 directly connected customers

^111(_[0-9]+)?$ -> AS111 and/or its directly connected customers

^[0-9]+$ -> My Directly connected ASs

^[0-9]+(_[0-9])?$ -> My Directly connected ASs and/or their customers

Hi Samer,

This is correct except the last one, it should be:

^[0-9]+(_[0-9]+)?$

HTH,
