我解析一个xml文件,以获取两个节点"tagid"和"mac"的内容.如何将此内容存储在两个数组中,一个用于"tagid",另一个用于"mac"？

"解析器"有效.先感谢您

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

    self.currentElement = elementName;
    self.currentElement2 = elementName;

    if ([self.currentElement isEqualToString:@"mac"]) {
        self.currentTitle = [NSMutableString string];

    }

    if ([self.currentElement2 isEqualToString:@"tagid"]) {
        self.currentTitle2 = [NSMutableString string];

    }
}

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

    if ([self.currentElement isEqualToString:@"mac"]) {
        NSLog(@"%@", self.currentTitle);
    }

    if ([self.currentElement2 isEqualToString:@"tagid"]) {
        NSLog(@"%@", self.currentTitle2);
    }

    self.currentTitle = nil;
    self.currentElement = nil;
    self.currentTitle2 = nil;
    self.currentElement2 = nil;

}

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

    if …

我试图在单个UIWebView中连续打开多个URL,但它只打开最后一个URL(最后一个成员macArray).

- (IBAction)openURL:(id)sender {

    macArray = [NSArray arrayWithObjects:@"XX:XX:XX:XX:XX:XX", @"XX:XX:XX:XX:XX:XX", nil];

    NSString *part1URL = @"http://myurl?mac=";
    NSString *part2URL = @"&dothis";

    for (int i = 0; i < macArray.count; i++) {
        NSLog(@"%@", macArray[i]);

        NSString *mac = [macArray objectAtIndex:i];

        NSString *beginURL = [part1URL stringByAppendingString:mac];
        NSString *URL = [beginURL stringByAppendingString:part2URL];

        NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:URL]];
        [webView loadRequest:request];
    }
}

有谁有想法吗？提前谢谢你,祝你有个美好的一天/晚上.

我的XML看起来如此:

<sensor>
<data>26.7</data>
<data>54.53</data>
<log>false</log>
</sensor>

要检索列表中的数据字段,我使用:

List<string> list = xml.Root.Descendants("sensor").Elements("data").Select(element => element.Value).ToList();

它运作良好.

有时XML看起来像这样(log = true):

<sensor>
<data>26.7</data>
<data>54.53</data>
<log>true</log>
</sensor>

我想忽略这些价值观.我怎样才能做到这一点？

我试过这个:

 var lastUser = xml.Element("response").Descendants("sensor")
                   .First(u => u.Element("data") != null
                                    && u.Element("log").Value == "false");

但我只能检索当然只有第一个值.
