Re: Regular Expresion

in reply to Regular Expresion

What did you try?

Rather than being daunted by the problem, try breaking it down into simple steps.

Field starts with ? or &
Continues with either
- username=
- alphameric string
or
- userid=
- numeric string
Field terminates with & or EOL

How would you implement something like this?

I think his problem isn't the "simple steps", but going from "simple steps" to a "complicated total". Given that the username may, or may not, preceed the userid, how would you proceed? How would you proceed if there could be 10 fields, in any order?	[reply]

I wouldn't use one regular expression. I'd use two -- one for the User ID, one for the name. State information tells you if they're both from the same line. I realize brevity is the soul of wit, but I occasionally prefer verbosity if it results in ease of support. (Translation: I'm not as good a programmer as the rest of you...)	[reply]

By that logic, you would come to the conclusion being a good programmer means everything is a one-liner. I disagree. Multiple lines wins except in the case of repeating yourself.	[reply]
