我正在尝试在这里解析 xml 并正确获取我的 CXMLElement。例如，一个记录这个

<CXMLElement 0x1d8cfdc0 [0x1c556660] TrackDetail <TrackDetail>Tracked</TrackDetail>>

但在这种情况下，我无法获取字符串值Tracked。我试过了

CXMLNode *title = [[fd objectAtIndex:indexPath.row] nodeForXPath:@"TrackDetail" error:nil];

但记录这个返回null。有人知道如何获取 CXMLElement 的 stringValue 吗？

这是示例xml

<TrackResponse>
 <TrackInfo ID="9400110200793563195827">
  <TrackSummary>
  The delivery status for this item has not been updated as of February 07, 2013, 11:34 pm.
  </TrackSummary>
  <TrackDetail>

我用这个解析它

NSArray *arr = [parser nodesForXPath:@"//TrackResponse/TrackInfo/TrackSummary" error:nil];
NSArray *p = [parser nodesForXPath:@"//TrackResponse/TrackInfo" error:nil];
if ([p count]>0) {
    for (CXMLElement *resultElement in p) {
        for(int counter = 0; counter < [resultElement childCount]; counter++) {
            NSLog(@"%@", [[[resultElement nodesForXPath:@"TrackDetail" error:nil] objectAtIndex:counter] stringValue]);
            [self.arr1 setObject:[[[resultElement nodesForXPath:@"TrackDetail" error:nil] objectAtIndex:counter] stringValue] forKey:@"det"];
        }
    }
}

这个怎么样：

NSMutableArray *array = [[NSMutableArray alloc] init];
NSArray *p = [parser nodesForXPath:@"//TrackResponse/TrackInfo" error:nil];
if ([p count]>0) {
    for (CXMLElement *resultElement in [[p objectAtIndex:0] elementsForName:@"TrackDetail"]) {
          [array addObject:[resultElement stringValue]];
        }
    }
}

无法测试它，但它类似于我以前使用过的一些代码。
