This may be a very weird question. However, please bare with me while<br>
I explain this.<br>
I was speaking with a friend over Skype (we're both visually impaired,<br>
so use Windows for pretty much everything) and my friend asked me to<br>
develop a program that can take the numbers of vehicles (he's a GTA<br>
fan, :)) in KMH (kilometers per hour) and convert it into MPH (miles<br>
per hour). To do this, I chose Swift for this task, as I think it<br>
might be a good challenge for it. I am using RemObjects Elements to<br>
use Swift on .NET, Java, Cocoa, and Island to develop applications for<br>
these platforms. Island is a new platform in RemObjects Elements that<br>
allows developers to develop applications that use native API<br>
functions from the operating system. For instance, on Windows, I could<br>
directly (without any imports) use CreateWindowEx and all that to<br>
create a new window. Sadly this cannot be ported to Mac OS X, as Cocoa<br>
is reserved for that. :)<br>
Anyways, back to the topic I'm trying to resolve. My friend gave me<br>
too files, specs_cars.txt and specs_motorcycles.txt. Both files are<br>
attached to this email (specs_cars.txt is nearly 45 KB in length and<br>
specs_motorcycles.txt is about 3.9 KB).<br>
So here's my question: I'm on .NET, so yeah, but how would I go about<br>
using regular expressions to only search with lines that contain KMH<br>
(I'll show you how I want it to be done) and replace the numbers of<br>
KMH, along with the KMH itself, with MPH numbers followed by MPH? If<br>
you guys could help me solve this, I would be grateful, as I don't<br>
want to develop an entire parser for something like this, so regular<br>
expressions seem to be the way to go.<br>
<br>
Allow me to show you: In the specs_motorcycles.txt file, this:<br>
0-100kmh: 3.9s<br>
Should be replaced with:<br>
0-62.14kmh: 3.9s<br>
<br>
Now, this looks simple, but what about something like:<br>
Top speed: 218 kmh<br>
to be replaced with:<br>
Top speed: 135.5 kmh<br>
I hope you see my problem. I hope you can help me through this, and we<br>
can solve it together. :)<br>
