regexp question

[Jabba Laci]

Hi,

How to find all occurences of a substring in a string? I want to
convert the following Perl code to Python.

Thanks,

Laszlo

my $text = '<a href="ad1">sdqs</a><a href="ad2">sds</a><a href=ad3>qs</a>';

while ($text =~ m#href="?(.*?)"?>#g)
{
   print $1, "\n";
}
# output:
#
# ad1
# ad2
# ad3
