I need to extract prices froma html-document.
[0-9]*\$ matches 112$ 45$ etc but also just a $. why that shouldnt
really matter and it is unlikely anyway to appear a $sign with no
price attahced to it I still want to prevent it.
How do I avoid matching "$"? It has to be "nbr$".
The answer to your question is to use a + instead of *. + matches 1
or more elements, * matches zero or more.
The second point to mention is that, at least where I come from, the
currency symbol comes before the number:
$112 and $45
In which case your regexp should be somehting like this: \$[0-9]+
