 |
|
hi there!
I started to concern myself with regexp now, and I already have a problem:
the string ($text):
| Code: | | <a href=/item.html?witem=647>Destiny</a> |
my code:
| Code: | | regexp {\.html\?witem=([0-9]*?)\>} $text result |
I know there's anything wrong with it, but I don't know what.
the match I get is: .html?witem=647>
but I want to get: 647
thanks for any help!
regards,
eiSi |

| Code: | | scan $text "<a href=/item.html?witem=%d>*</a>" digit |
647 is stored in $digit. |

There's nothing wrong with your regexp, you just missed the 2nd var at the end.
Regexp writes the entire matching pattern to the first var.
So this should work: | Code: | | regexp {\.html\?witem=([0-9]*?)\>} $text garbage result |
You dont have to make it this complex, though. You could probably have gotten away with doing something like this: | Code: | | regexp {witem=(.*?)>} $text . digit |
