non greedy
Imagine you have the following text:
<br />'Stupid ad'<br /><br />Real content<br />
If you use the regular expression
<br />'Stupid.*<br />
then you will match the complete text, not just the 'Stupid ad'. That is because '.' is greedy. If you want it to not be greedy, try:
<br />'Stupid.*?<br />
Now you should only match
<br />'Stupid ad'<br />
because you are using a non greedy search.
