This is because of the "greediness" of *: It gobbles up all it can.
You could either use a "non-greedy" match (.*?), or you could use a
character class instead of the ".".
That would give you
/^<$g_date.*method: (.*?\. )/
or
/^<$g_date.*method: ([^.]*\. )/
I'm not sure if there is any difference between those two
performance-wise. They should do the same thing anyhow.
