私はデリゲートメソッドを使用していますNSXMLParser:

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
    attributes:(NSDictionary *)attributeDict {


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

- (void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string

タイトルを取得するには、didEndElementメソッドでこれを行うだけです:

if ([elementName isEqualToString:@"title"]){
        self.aArticle.title = self.currentElementValue;
    }

ただし、これを試してみるとうまくいきません。説明全体でノードに@"p" アクセスする方法を考えてみてください。< p >

これに対するより良い方法/解決策はありますか?

foundCharactersNSLogで文字列を印刷すると、次のようになります。

<
2013-03-18 00:42:31.978 newsFeed[67052:c09] string is p
2013-03-18 00:42:31.978 newsFeed[67052:c09] string is >
2013-03-18 00:42:31.979 newsFeed[67052:c09] string is Tysor will work closely with national security thrust leader Jon Greene and with cognition and communication thrust leader Jeff Reed, a professor of electrical and computer engineering in the College of Engineering and director of Wireless@VT.
2013-03-18 00:42:31.979 newsFeed[67052:c09] string is  
2013-03-18 00:42:31.979 newsFeed[67052:c09] string is <
2013-03-18 00:42:31.979 newsFeed[67052:c09] string is /p
2013-03-18 00:42:31.979 newsFeed[67052:c09] string is >

今考えられる唯一の方法は< p >、メソッド foundCharacters で見つかった場所を追跡し、囲んでいる< p >タグ内の値に到達したかどうかをチェックするカウント変数を使用する方法です。

この方法を試してみてください

VC.m

NSMutableString *xmlString;

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)nameSpaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
    if (!xmlString)
        xmlString = [[NSMutableString alloc] init];
    else
        [xmlString setString:@""];
}

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

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{    
    if ([elementName isEqualToString:@"p"])
    {
        if (![xmlString isEqual:@""])
        {
            NSLog(@"%@",xmlString)'
            [SomeArray addObject:xmlString];
        }
    }

    //Release string
    [xmlString release];
    xmlString = nil;
}

これを使ってみてください..

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
     // ----------- Current Element Name means it is equal to <p> tag -----------
     if([self.currentElementName isEqualToString:@"p"])
     {
         NSLog(@"Value %@",string);
     }
}
