iPhone TBXML循环和解析数据

Question

基本上我有一个返回的XML响应和一个字符串,我需要遍历xml并将所有信息存储在一个数组中.这是xml

<?xml version="1.0" encoding="UTF-8"?>

我需要那些2 <records>和所有数据存储在一个数组中.所以....

记录数组 - >记录数组 - >每个记录的数组,数据....

我一直坐在这里试图使用TBXML来解决这个问题,这很容易抓住一个节点....但我不能这样做:(

好吧,你的第一步是创建一个解析数据的类.RecordParser例如,打电话给它.我们现在需要在标题中添加几个方法,以及a NSMutableArray.

@interface RecordParser : NSObject {
    NSMutableArray *records;    
}
@property(nonatomic,retain)NSMutableArray *records;

-(void)loadRecords:(NSString *)records;
-(void)traverseElement:(TBXMLElement *)element;

@end

现在,继续并充实您的实施.我们现在需要实现这两种方法来完成我们希望他们做的事情.

- (void)loadRecords:(NSString *)records {
    NSString *someXML = @"http://www.something.com/somexml.xml";
    TBXML *tbxml = [[TBXML tbxmlWithURL:[NSURL URLWithString:someXML]] retain];

    records = [NSMutableArray array];
    [records retain];

    if (tbxml.rootXMLElement)
        [self traverseElement:tbxml.rootXMLElement];
    [tbxml release];
}

基本上该方法将获取有问题的XML文件并开始解析过程.此外,您正在初始化阵列并保留它.现在我们来看看奶酪吧.

- (void) traverseElement:(TBXMLElement *)element {
    do {
        if (element->firstChild) 
            [self traverseElement:element->firstChild];

        if ([[TBXML elementName:element] isEqualToString:@"Record"]) {
            TBXMLElement *destination = [TBXML childElementNamed:@"Destination" parentElement:element];
            TBXMLElement *status = [TBXML childElementNamed:@"Status" parentElement:element];
            TBXMLElement *guid = [TBXML childElementNamed:@"GUID" parentElement:element];
            TBXMLElement *dateSub = [TBXML childElementNamed:@"DateSubmitted" parentElement:element];
            TBXMLElement *dateToSend = [TBXML childElementNamed:@"DateToSend" parentElement:element];
            TBXMLElement *dateSent = [TBXML childElementNamed:@"DateSent" parentElement:element];
            TBXMLElement *dateReceived = [TBXML childElementNamed:@"DateReceived" parentElement:element];
            TBXMLElement *message = [TBXML childElementNamed:@"Message" parentElement:element];
            TBXMLElement *id = [TBXML childElementNamed:@"ID" parentElement:element];

            [records addObject:[NSArray arrayWithObjects:
                                  [TBXML textForElement:destination],
                                  [TBXML textForElement:status],
                                  [TBXML textForElement:guid],
                                  [TBXML textForElement:dateSub],
                                  [TBXML textForElement:dateToSend],
                                  [TBXML textForElement:dateSent],
                                  [TBXML textForElement:dateReceived],
                                  [TBXML textForElement:message],
                                  [TBXML textForElement:id],nil]];  
        }
    } while ((element = element->nextSibling));  
}

基本上该方法所做的是横向XML文件寻找具有您正在寻找的名称的元素,然后它从子节点获取数据.此外,数据将添加到records阵列中.所以基本上,当它完成时,它应该拥有你想要的数据records,你可以操纵你想要的所有数据.

这是完全未经测试的.如果它炸毁你的电脑并杀死你的猫,不要怪我.我通常不会把所有的工作都写成这样一个完整的方法,但我碰巧喜欢TBXML.如果有效,请告诉我.我真的很感激知道.
