How to match multiple occurrences of a substring
Adding /g
isn't enough if you wish to match multiple occurrences of a substring. If that's the case, reluctant quantifiers may be used as described herein.
Given the string:
<div><p>£20<span class="abc" /><span class="def">56</span></p></div>
You will arrive at the text you wanted using:
\d+.*>\d+
But given the same string repeated two times:
<div><p>£20<span class="abc" /><span class="def">56</span></p></div><div><p>£20<span class="abc" /><span class="def">56</span></p></div>
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.
Just allow the group to be repeated: (?:...)+
means "Match ...
1 or more times:
str.match(/\d+(?:<[^>]*>)+\d+/)
As per Alan Moore's suggestion, I've also changed the \d*
into \d+
, making the numbers required instead of optional.
To match multiple times use to need use the global option
str.match(/your_expression_here/g)
