如何使用 HtmlAgilityPack 获取子锚点的属性?

How to get attribute of child anchor with HtmlAgilityPack?

我正在学习HtmlAgilitiPack,我想问你,如何获取值(我想获取这个值):

来自 HTML 页:

<div id="js_citySelectContainer" class="select_container city_select shorten_text replaced"> 
<span class="dropDownButton ownCity coords">
<a>i want get this value</a>
</span>
</div>

C# 代码:

HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
doc.LoadHtml(html);
Console.writeln(echo i want get this value);

我试过:

doc.DocumentNode.Descendants("span").Where(s => s.GetAttributeValue("class", "") == "dropDownButton ownCity coords").First().InnerText;

但是没有用,你能帮帮我吗?谢谢。

您可以使用 XPATH 语法:

var span = doc.DocumentNode.SelectSingleNode("//span[@class='dropDownButton ownCity coords']");
var anchorText = span.ChildNodes["a"].InnerText;

您也可以使用 LINQ:

var anchorTexts = 
    from span in doc.DocumentNode.Descendants("span")
    where span.GetAttributeValue("class", "") == "dropDownButton ownCity coords" 
    from anchor in span.Descendants("a") 
    select anchor.InnerText;
string anchorText = anchorTexts.FirstOrDefault();

我认为您正在尝试获取 span 文本,您需要 a 文本

试试这个

doc.DocumentNode.Descendants("span")
.Where(s => s.GetAttributeValue("class", "") == "dropDownButton ownCity coords")
.First().Descendants("a").First().InnerText;
