Removing dots - please help me out

Could you please help me out with regular expressions. I'm trying to
write a perl script that proccesses some text, and i'm stuck at the
following:

need to remove from the text
1. dots followed by space & words starting with lower case letters
2. dots followed by only by words starting with lower case letters

ie

"pure text here bla bla bla. more text follows" --> changes to
"pure text here bla bla bla more text follows"

and

"pure text here bla bla bla.more text follows" --> changes to
"pure text here bla bla bla more text follows"

Need to remove just the dots, not letters.

No matter how hard i tried, i could not make it work. Tried various
things eg $line =~ s/\. (?=[a-z])/ /g; I'd really appreciate your
help, it's a must do and dont have anyone else to help out.

Thanks in advance.

You seem to be close, but since the dot may or may not be followed by
a space, you'd better say so:

s/\. ?(?=[a-z])/ /g;
---------^

Thanks, it does seem to work correctly.
However, there are still some dots that are not being removed,
for example when there is a 'return' after the dot:

"Asthma in children of sycotic parents ( Nat .
s ) Spasms of the glottis with clucking in the larynx ; air "

Ofcourse i'm using first
$line =~ s/\n//g;
in order to remove the return characters and then
$line =~ s/\. ?(?=[a-z])/ /g;
but these dots still escape.

Any ideas why it doesnt work ?

Please ignore my last message about some dots after returns, escaping the regex.
It was my mistake, needed to re-apply the regex a second time at a different point.
Thnx
