Get numbers from string with regex

Question

I am trying to write a regex to get the numbers from strings like these ones:

javascript:ShowPage(\'6009\',null,null,null,null,null,null,null)
javascript:Bloc         


        

Answer 1

Assuming:

• you want to capture the digits
• there's only one set of digits per line

Try this:

/(\d+)/

then $1 (Perl) or $matches[1] (PHP) or whatever your poison of choice is, should contain the digits.

Answer 2

Try this:

(\d+)

What language are you using to parse these strings?

If you let me know I can help you with the code you would need to use this regular expression.

Answer 3

just match numbers: \d+

Answer 4

// PHP

$string = 'ssss 12.2';
$pattern = '/\D*(\d+)(.|,)?(\d+)?\D*/';

$replacement = '$1.$3';

$res = (float)preg_replace($pattern, $replacement, $string);

// output 12.2

Answer 5

Integer or float:

/\d+((.|,)\d+)?/
