Where can be a problem?

[Lad]

I use the following
###############
import re
Results=[]
data1='<a href="detailaspxmember=15015&mode=advert" </a><a
href="detailaspxmember=15016&mode=advert" </a><a
href="detailaspxmember=15017&mode=advert" </a>'
ID = re.compile(r'^.*=(\d+)&.*$',re.MULTILINE)
Results=re.findall(ID,data1)
print Results
#############
to extract from data1 all numbers such as 15015,15016,15017

But the program extracts only the last number 15017.
Why?
Thank you for help
La.
