How do I look for all the alert and confirm prompts in a given web page using Regular Expressions?

Question

I need to look for all the alert and confirm prompts i a given web page.

How do I do that using Regular Expressions?

Currently I am using

alert\\(.*\\)|confirm\\(.*\\)

It works fine if the alert and confirm are on different lines.
However it will return only the alert prompt if they are on the same line.
e.g. alert('Hello World');confirm('Yes?');

What am I doing wrong? Please advice. Thanks!!

Answer 1

in regular expressions the repetition operator are greedy, that means that they will continue searching even after they've found a match until the string is exhausted. so in your case
   alert\(.*\)   will match alert('Hello World');confirm('Yes?')
so to make it lazy we can add a '?' after the repetition operator as
   alert\(.*?\)|confirm\(.*?\)

hope this works.
