iphone - 使用 touchXML 解析 SOAP 响应 - 一个问题

Question

我还有 obj-c 的另一个问题:我正在尝试解析此 XML:

情况如下:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <GetMyDashboardResponse xmlns="http://tempuri.org/">
            <GetMyDashboardResult>
                <MyDashboard>
                    <Profile>Speed Seeker</Profile>
                    <UserID>6</UserID>
                    <VenueName>Prasowa</VenueName>
                    <FriendsCount>10</FriendsCount>
                    <FollowingCount>11</FollowingCount>
                    <FollowersCount>12</FollowersCount>
                    <StatusMessage>aaa</StatusMessage>
                    <StatusDate>2010-08-04T11:38:09.733</StatusDate>
                    <CheckedInTimeStamp>2010-07-30T13:48:24</CheckedInTimeStamp>
                </MyDashboard>
            </GetMyDashboardResult>
        </GetMyDashboardResponse>
    </soap:Body>
</soap:Envelope>

这就是我试图实现它的方法:

NSMutableArray *res = [[NSMutableArray alloc] init];

CXMLDocument *doc = [[[CXMLDocument alloc] initWithData:XMLData options:0 error:nil] autorelease];

NSArray *nodes = NULL;
nodes = [doc nodesForXPath:@"//MyDashboard" error:nil];

for (CXMLElement *node in nodes) 
{
      NSMutableDictionary *item = [[NSMutableDictionary alloc] init];
      int counter;
      for(counter = 0; counter < [node childCount]; counter++) 
      {
            [item setObject:[[node childAtIndex:counter] stringValue] forKey:[[node childAtIndex:counter] name]];
      }
      [item setObject:[[node elementsForName:@"Profile"] stringValue] forKey:@"profileName"];  // <------ this magical arrow is pointing to the area of interest
    NSLog(@"petla");
      [res addObject:item];
      [item release];
}

NSLog(@"%@", res);
[res release];

`

感谢您的帮助。

[node elementsForName] 将返回 NSArray，因此您绝对不能在其上使用 stringValue 。创建临时 NSArray，为其设置 elementsForName，检查其对象计数是否 > 0，获取 objectAtIndex:0 就可以了!
