Let’s say i have a xml file with a tag named which contains the number of fields i want to show in my tableView and in another xml file i have the information to be displayed in that tableView.
The question is : Should i create 2 different file in my project (xmlparse1.h and .m + xmlparse2.h and .m) or should i just put all my code in 1 (xmlparse.h + .m) and differenciate which file i am parsing at the moment with a bool or something like that in the code?
I am developing an iphone app on Xcode 4.3 mac os x 10.7.4 if this might change
EDIT: 1st file :
<MenuPrin>
<humidite>82,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0</humidite>
<tempmoy>
189,124,700,700,700,700,700,700,700,700,700,700,700,700,700,700,700,700,700,700
</tempmoy>
</MenuPrin>
2nd File :
<Instal>
<nbrField>2</nbrField>
</Instal>
So it looks like this. So, since nbrField is 2 I would take the 2 first value from tempMoy and humidite and show them in a tableView.
END OF EDIT
If how you’re parsing is similar in both instances, to add two sets of files that do effectively the same thing would be extremely inefficient and considered bad practice. It makes a lot more sense to create a parser that can handle the two different files than to write two parsers that can only handle a specific file each.
To more specifically answer your question, I would determine which file you are parsing and behave accordingly, whether you do this with a bool or something else is up to you.
EDIT: Here is the idea that just popped into my head, so if for whatever reason this wont work for you(Like I said its been a while), or someone has a better idea, I’m all ears. You could still have a set of files(.h and .m) that contain the definition of your parser. Your parser could contain within it a two variables of type Object1 and Object2 which are built in such a way that they resemble the data structure that you need to store what you parse once for your first type of file, and a different definition for your second type of file. This way when parsing once you determine which file it is you are reading, it just changes which of these two objects you write into. There are also plenty of variations for how you could set this up, and I can also think of a few cases for what you might be trying to do where this might not work, but there is the idea regardless.
If you think that the two sets of files approach is better for the application you are trying to write and makes more sense to you, given what has been discussed in the comments, it isn’t necessarily a bad idea.
