Question

我正在开发一个调用API的项目，它返回一个Xml数据，在我的代码类里面有解析数据并将其提取到UI上显示（这里使用了NSXMLParser）。我附加了屏幕截图xml响应和为解压缩数据而编写的代码部分（解析代码我不在这里粘贴）

提取代码：

 else if ([adType isEqualToString:@"textAd"])
    {
        NSString *html = [xml.documentRoot     getNamedChild:@"htmlString"].text;

        CGSize bannerSize;
        if(adspaceHeight > 0 && adspaceWidth > 0)
        {
            bannerSize = CGSizeMake(adspaceWidth, adspaceHeight);
        }
        else if (UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPad)
        {
            bannerSize = CGSizeMake(728, 90);
        }
        else
        {
            bannerSize = CGSizeMake(320, 50);
        }

        UIWebView *webView=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, bannerSize.width, bannerSize.height)];

        //load HTML string later (to avoid calling impression pixels when using custom events)
        if(!headers) { //means that it's an interstitial ad
            _htmlString = [NSString stringWithFormat: @"<style>*
          { -webkit-tap-highlight-color: rgba(0,0,0,0);} body {height:100%%;                width:100%%;
} 
       img {max-width:100%%;
       max-height:100%%; width:auto; height:auto; position: absolute; margin: auto; top: 0; left: 0; right: 0; bottom: 0;}
</style>
%@",html];
        } else {
            _htmlString = html;
        }


        if([skipOverlay isEqualToString:@"1"]) {

            wasUserAction = NO;

            webView.delegate = (id)self;
            webView.userInteractionEnabled = YES;

            UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapGesture:)];

            [webView addGestureRecognizer:tap];

            tap.delegate = self;


        } else {

            webView.delegate = nil;
            webView.userInteractionEnabled = NO;

//          add overlay later, only if no custom event is shown
        }
        webView.backgroundColor = [UIColor clearColor];
        webView.opaque = NO;
        webView.scrollView.scrollsToTop = false;

        self.bannerView = webView;
  }

现在对我来说，我想为另一个xml结构修改相同的代码...... 我正在粘贴我必须处理的响应的屏幕截图。请帮助我检索每个节点内的数据。（特别是“ads”标签内有两个链接。如何单独检索它们）。
