Question

请检查下面的代码。我正在尝试从此html文档中获取html文本值。我想获取文本Quick Kill 32 oz. Mosquito Yard Spray，并且我已经尝试使用SelectSingleNode来实现，例如波纹管，但这无法获取此文本值。知道如何解决吗？

string html = @"<div class='pod-plp__description js-podclick-analytics' data-podaction='product name'>
    <a class='' data-pos='0' data-request-type='sr' data-pod-type='pr' href='/p/AMDRO-Quick-Kill-32-oz-Mosquito-Yard-Spray-100530440/304755303'>
    <span class='pod-plp__brand-name'>AMDRO</span> 
    Quick Kill 32 oz. Mosquito Yard Spray
    </a>
</div>";

var doc = new HtmlDocument();    
doc.Load(html);

string title = doc.DocumentNode
    .SelectSingleNode("//div[@class='pod-plp__description js-podclick-analytics']span[@class='pod-plp__brand-name']")
    .InnerText;

Answer 1

您正试图仅定位span[@class='pod-plp__brand-name']，这只会使您在跨度范围内返回，但是您需要following-sibling::text()才能在跨度之后获取文本。请参见下面的示例代码。您也可以从html-agility-pack官方网站上了解更多信息。

var Content = htmlDoc.DocumentNode.SelectSingleNode("//span[@class='pod-plp__brand-name']/following-sibling::text()[1]");

string title = titleAgain.InnerText.Trim();
