XML parsing done, load from URL.

[railion]

Hello guys!
Okay, so I finally managed to get my little XML parsing script to work! Fantastic! But I ain't satisfied.. not yet!
I've Googled around a bit, trying to find a thread that could teach me how to load my XML file from a specified URL adress - but without luck.
So now I'm a bit lost.
Do any of you have any luck loading XML data from a URL adress?

Thanks for your help!

Rail.

just download the xml with NSURLConnection or ASIHTTPRequest, and then use stringResponde as xml.......

see section 4, there are some examples: http://www.iphonedevsdk.com/forum/ip...rvice-how.html

My problem is more; how do I combine the XML parser and the NSURLCon.?
I think I'm getting this wrong

1. Download XML file using NSURL Connection or ASIHTTP
2. On Download Complete, create xml parser and parse as normal
3. Everything else is the same

At this time, to locate my XML file (local in my project) I'm using:

NSString * path = [[NSBundle mainBundle] pathForResource:@"Test" ofType:@"xml"];

Just to be sure I get this right. The only thing I've to do is to point my path to a URL using the URLConnection?

can you open the link posted above and read code in section 4 or is too effort for you?

You just need to download the file and use the stringResponse (that will be the xml).


you could also do that

NSString *responseString = [[NSString alloc] initWithContentsOfURL:yourURL encoding:anEncoding error:nil];
//use responseString
[responseString  release];

but it is a synchronous request, so used on main thread freeze the UI during download....

dany_dev: I've taken a look at your post and it looks great - I'm also starting to figure it out, I'm just a little bit slow in learning, ehh Sorry!
Anyway, I'm just having a little problem putting the bricks in the wall together, but I guess I'll figure it out sooner or later.
I really appreciate the help you're giving me - a huge thanks for that

Okay, a little update.
I think I'm getting closer Using a little different way though.

   
NSString *filePath = @"URL";
NSURL *url=[[NSURL alloc] initWithString:filePath];
NSString *fileContent = [[NSString alloc] dataWithContentsOfFile:url]; NSXMLParser* parser = [[NSXMLParser alloc] initWithData:fileContent];
[parser setDelegate:self];
[parser parse];
[parser release];
[super viewDidLoad];

Still not working 100%.

[dany_dev]

there are many weird things on your code


1-this line don't make sense for 2 reason: NSString don't have a method called "dataWithContentsOfFile". Second reason, also supposing that this method exist, you are using alloc and then a method that return an autoreleased object, don't make sense, should be [[NSString alloc] initWithData:aDataObject];

NSString *fileContent = [[NSString alloc] dataWithContentsOfFile:url];

2-Why you are using initWithData passing a string? if you want to use initWithData: you need to pass a NSData*, fileContent is a NSString*

NSXMLParser* parser = [[NSXMLParser alloc] initWithData:fileContent];

3-I advice you to use a delegate for NSXMLParser that is not self, to avoid too confusion on your view controller (I assume that self is your view controller)



The right code should be:

NSString *urlString = @"insert your url";
NSURL *url=[[NSURL alloc] initWithString:urlString];
NSXMLParser* parser = [[NSXMLParser alloc] initWithContentsOfURL:url];
[parser setDelegate:self];
[parser parse];
[parser release];

FYI, the I removed the URL because I didn't wanted to share it with the whole internet :-)
Anyway, thanks for a quick answer, I'll test it right away.

Argh, SIGABRT and this line marked with green:

int retVal = UIApplicationMain(argc, argv, nil, nil);

I think I've taking on a too big project. I should read a bit more, before trying to make this.

***UPDATE***
I made a clean start; trying all over and apparently it works now!
Again, dany_dev, thank you so much for your patience and your help I've bookmarked your link, and I can tell I'm going to do some reading now
Have a nice day, there.
Cheers from Denmark!
