| Ok, I like to think that Im farely skilled with reg exp by now, but I still cant get this... On the MUD I play there is something that shows the amount of exp gained over the total time youve played
|Exp gained | 0 |
however, this can change, but the format always is the same width
Ex:
|Exp gained | 0 |
|Exp gained | 10235320 |
I would like a trigger to match that line, but have a reg exp to gather the amount of xp total. I cant get it to match because it always changes in the amount of spaces before the second | and the digits... ive tried using * but keep getting 'Nothing to repeat at offset'
Any ideas?

| I would do something like this:
^\| Exp gained \|\s+(\d+)\s+\|$
In regexps saying (something)+ means "one or more of something", and using \s means "a whitespace character", so putting it together, \s+ means one or more spaces.
Similarly \d means a digit (0 - 9). |

| ok, but when i put the \d+ part into () it doesnt work anymore...
|\s+(\d+)\s+| <-- Doesnt match anything... should I put the \s+ 's into () also? |

| Do you need the wildcard to put into a variable?
The \d+ doesn't save the number to a variable, so you'd have to do:
^\| Exp gained \|\s+(.*)\s+\|$
I think. It's been a while since I've had to use regular expressions like that. |
My code(with a LOT of Nicks help) to fame:
sub OnAutoCombo (TriggerName, TriggerLine, arrWildCards)
dim AutoCombo
AutoCombo = split (arrWildCards (1))
Dim i, attack
for i=lbound (AutoCombo ) to ubound (AutoCombo )
Select Case AutoCombo (i)
case "rp" attack = "punch right"
case "lp" attack = "punch left"
case "s" attack = "sweep"
case "r" attack = "roundhouse"
case else attack = "" ' unknown attack type
End Select
if i = ubound (AutoCombo ) then
world.send "throw " + world.getvariable ("attacker") + " down"
else
world.send attack + " " + world.GetVariable ("attacker")
end if
next
end sub

| | Everything returns if you enclose it in parentheses... Maybe you have to escape the pipes (|) though? |

It will with the brackets around it, that is why I had them.
You need to escape the "|" symbols, as I did in my earlier post, otherwise they have the meaning "this" OR "that". |

I dont see the brackets that you said to put there, so thats why I inquired as to why it wasnt returning anything and what should be put into brackets

| Hmmm - my brain must have malfunctioned there. :)
I have amended the post to put the brackets in.
However looking at your original post a bit more closely, I see you have more spaces than are obvious between the vertical bars. So it should probably read:
^\|\s*Exp gained\s*\|\s+(\d+)\s+\|$
The extra \s are to allow for the spaces on each side of "Exp gained" - by following by "*" it means zero or more, which would allow for the "Exp" being hard up against the bar. |
