Found it: There were cases where the URL was followed by other
attributes:
==========
<a href="/places/0.php">dummy<a href="/places/1.php"
class="N11">dummy<a href="/places/2.php">
==========

This code does the job:
==========
for w in string.gmatch(line, '<a href="/places/%w%.php">') do
==========

Thank you all.
