webservicex.net、 for 、および iPhone Appから次の xml を解析する必要があります。私は詩をいくつかの NSArray/NSDictionary か何かに保存する必要がありVerseますBibleWords。

<string xmlns="http://www.webserviceX.NET">
<NewDataSet>
  <Table>
    <Book>1</Book>
    <BookTitle>Genesis</BookTitle>
    <Chapter>1</Chapter>
    <Verse>1</Verse>
    <BibleWords>In the beginning God created the heaven and the earth.</BibleWords>
  </Table>
  <Table>
    <Book>1</Book>
    <BookTitle>Genesis</BookTitle>
    <Chapter>1</Chapter>
    <Verse>2</Verse>
    <BibleWords>And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.</BibleWords>
  </Table>
  <Table>
    <Book>1</Book>
    <BookTitle>Genesis</BookTitle>
    <Chapter>1</Chapter>
    <Verse>3</Verse>
    <BibleWords>And God said, Let there be light: and there was light.</BibleWords>
  </Table>
  <Table>
    <Book>1</Book>
    <BookTitle>Genesis</BookTitle>
    <Chapter>1</Chapter>
    <Verse>4</Verse>
    <BibleWords>And God saw the light, that it was good: and God divided the light from the darkness.</BibleWords>
  </Table>
</NewDataSet>
</string>

データを解析するために次のコードを書きました。

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {
    if ([elementName isEqualToString:@"string"]) {
        model = [[Model alloc]init];        
    }
}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
    if(!currentElementValue) {
        currentElementValue = [[NSMutableString alloc]initWithString:string];
    }

    else {
        [currentElementValue appendString:string];
    }

    NSLog(@"%@", currentElementValue);
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
    if ([elementName isEqualToString:@"NewDataSet"]) {
        return;
    }

    if ([elementName isEqualToString:@"Table"]) {
        [verses addObject:model];
        model = nil;
    }
    else {
        [model setValue:currentElementValue forKey:elementName]; //The exception break point hits here
    }    

    currentElementValue = nil;
}

currentElementValueが正しく表示されます。modelは、という名前のクラスのオブジェクトでModelありcurrentElementValue、NSMutableStringオブジェクトversesはNSMutableArrayです。私は Objective C の初心者で、これまで解析を行ったことがありません。問題は、その方法です：

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName

期待どおりに動作していません。コードでコメントした例外ブレークポイントに達した後、アプリが壊れました。Verseandの値を取得しBibleWordsて some に保存するにはどうすればよいですかNSArray/NSMutableArray/NSDictionary/NSMutableDictionary。問題が実際にどこにあるかを確認するために、他に言及する必要があるかどうかを尋ねてください。

これで試しました：

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {
    captureCharacters = NO;
    [currentElementValue setString : @""];
    if ([elementName isEqualToString:@"Table"]) { //set a break point here as well. The elementName is string and hence is not entering any of the conditions in this delegate method. Hence captureCharacters is always set to NO and nothing is working.
        model = [[Model alloc]init];        
    }
    else if ([elementName isEqualToString:@"Verse"]) {
       capturingCharacters = yes;
    }

    else if ([elementName isEqualToString:@"BibleWords"]) {
       capturingCharacters = yes;
    }
}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
    if(capturingCharacters) {
        [currentElementValue appendString:string];
    }
 }

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
    if ([elementName isEqualToString:@"Table"]) {
        [array addObject : model];
        model = nil;        
    }
    else if ([elementName isEqualToString:@"Verse"]) { //set a break point here
       model.Verse = currentElementValue; //not entering this condition
    }

    else if ([elementName isEqualToString:@"BibleWords"]) {
       model.BibleWords = currentElementValue; //not entering this condition
    }          
}

model.Verseそれは機能しておらず、との null 値を取得していますmodel.BibleWords。これらの方法はどのように機能しますか?

EDIT-2
モデル インターフェイス:

//model.h
@protocol HttpRequestHandler <NSObject>

- (void)returnFromSiteParsedData:(NSMutableArray *)parsedData;

@end

@interface Model : NSObject <NSURLConnectionDelegate, NSXMLParserDelegate>
{
    NSString *urlToLoad;
    NSMutableURLRequest *requestSiteToSendData;
    NSURLConnection *connectionToSiteToSendData;

    NSString *verseText;
    int verseNumber;

}
@property(nonatomic, retain) NSString *verseText;
@property(nonatomic, assign) int verseNumber;

- (void)loadSiteToSendDataWithChapterNumber:(int)chapterNumber AndBookNumber:(int)bookNumber;

@property(nonatomic, retain)id<HttpRequestHandler>httpRequestHandlerDelegate;

@end

モデルの実装

//model.m
@implementation Model

@synthesize verseNumber;
@synthesize verseText;

- (void)loadSiteToSendDataWithChapterNumber:(int)chapterNumber AndBookNumber:(int)bookNumber {

    urlToLoad = [[NSString alloc]initWithFormat:@"http://www.webservicex.net/BibleWebservice.asmx/GetBibleWordsByBookTitleAndChapter?BookTitle=Genesis&chapter=1"];
    requestSiteToSendData = [NSMutableURLRequest requestWithURL:[[NSURL alloc]initWithString:urlToLoad] cachePolicy:NSURLRequestReloadIgnoringCacheData  timeoutInterval:30];
    connectionToSiteToSendData = [[NSURLConnection alloc]initWithRequest:requestSiteToSendData delegate:self];    

}

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {

    // Parse the XML into a dictionary
    NSXMLParser *parser = [[NSXMLParser alloc]initWithData:data];
    VBSParser *vbsParser = [[VBSParser alloc]initVBSParser];
    [parser setDelegate:vbsParser];
    BOOL success = [parser parse];

    if (success) {
        NSMutableArray *verses = [vbsParser verses];
        NSLog(@"%@", verses);
        NSLog(@"Number: %d\n Text: %@", verseNumber,verseText);
        [self.httpRequestHandlerDelegate returnFromSiteParsedData:verses];
    }
    // Print the dictionary

}

@end

デリゲートは、解析されたデータをビュー コントローラーに返すために使用されます。
