XML を解析して、以前に他の XML で行った RSSEntry クラスに保存できるようにしたいと考えています。問題は、私が扱った他の XML だけがオンラインにあり、メソッドの一部として ASIHttpRequest クラスを使用しており、コードを変更して適合させる方法がわからないことです。私は現在このコードを使用しています：
- (void)viewDidLoad {
[super viewDidLoad];
self.allEntries = [NSMutableArray array];
self.queue = [[[NSOperationQueue alloc] init] autorelease];
self.feeds = [NSArray arrayWithObjects:@"http://316apps.com/LakesideNews/feed/",
nil];
NSLog(@"%@", self.feeds);
[self refresh];
}
- (void)refresh {
for (NSString *feed in _feeds) {
NSURL *url = [NSURL URLWithString:feed];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDelegate:self];
[_queue addOperation:request];
}
}
- (void)parseRss:(GDataXMLElement *)rootElement entries:(NSMutableArray *)entries {
NSArray *channels = [rootElement elementsForName:@"channel"];
for (GDataXMLElement *channel in channels) {
NSString *blogTitle = [channel valueForChild:@"title"];
NSArray *items = [channel elementsForName:@"item"];
for (GDataXMLElement *item in items) {
NSString *articleTitle = [item valueForChild:@"title"];
NSString *articleUrl = [item valueForChild:@"guid"];
NSString *articleDateString = [item valueForChild:@"pubDate"];
NSDate *articleDate = [NSDate dateFromInternetDateTimeString:articleDateString formatHint:DateFormatHintRFC822];
NSString *articleImage = [item valueForChild:@"content:encoded"];
RSSEntry *entry = [[[RSSEntry alloc] initWithBlogTitle:blogTitle
articleTitle:articleTitle
articleUrl:articleUrl
articleDate:articleDate
articleImage:articleImage] autorelease];
[entries addObject:entry];
}
}
}
- (void)parseFeed:(GDataXMLElement *)rootElement entries:(NSMutableArray *)entries {
if ([rootElement.name compare:@"rss"] == NSOrderedSame) {
[self parseRss:rootElement entries:entries];
} else if ([rootElement.name compare:@"feed"] == NSOrderedSame) {
[self parseAtom:rootElement entries:entries];
} else {
NSLog(@"Unsupported root element: %@", rootElement.name);
}
}
- (void)requestFinished:(ASIHTTPRequest *)request {
[_queue addOperationWithBlock:^{
NSError *error;
GDataXMLDocument *doc = [[GDataXMLDocument alloc] initWithData:[request responseData]
options:0 error:&error];
if (doc == nil) {
NSLog(@"Failed to parse %@", request.url);
} else {
NSMutableArray *entries = [NSMutableArray array];
[self parseFeed:doc.rootElement entries:entries];
[[NSOperationQueue mainQueue] addOperationWithBlock:^{
for (RSSEntry *entry in entries) {
int insertIdx = [_allEntries indexForInsertingObject:entry sortedUsingBlock:^(id a, id b) {
RSSEntry *entry1 = (RSSEntry *) a;
RSSEntry *entry2 = (RSSEntry *) b;
return [entry1.articleDate compare:entry2.articleDate];
}];
[_allEntries insertObject:entry atIndex:insertIdx];
[self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:insertIdx inSection:0]]
withRowAnimation:UITableViewRowAnimationRight];
}
}];
}
}];
}
- (void)requestFailed:(ASIHTTPRequest *)request {
NSError *error = [request error];
NSLog(@"Error: %@", error);
[self refresh];
}
Title のすべての領域を姓などに変更する方法はわかっていますが、GDataXML を取得してネストされた XML の解析を開始する方法がわかりません。
