How to match multiple occurrences of a substring

Question

If I have an HTML string such as:

£2056
<         


        

Answer 1

Adding /g isn't enough if you with to match multiple occurrences of a substring. If that's the case reluctant quantifiers may be used as described here.

Given the string:

£2056

You will arrive at the text you wanted using:

\d+.*>\d+

But given the same string repeated two times:

£2056
£2056

You will not find the target selection multiple times. You'll only find it once due to the greedy nature of .*. To make .* non-greedy, or reluctant, simply add a ? after the * and you will arrive at:

\d+.*?>\d+

Which will find both occurrences of the substring you asked for as shown here.
