I am interested in 2 elements of the html but I have no idea the best way to get to them. How would be the best way for me to get the value from and get the inner html from the element

推荐答案

• 下载 HTML敏捷性包（免费）


• 创建一个新的HTMLDocument


• loadhtml


• 使用DOM导航或XPath查询（的SelectSingleNode等）来查找元素


• 您想要的元素访问InerHtml

• download the HTML Agility Pack (free)
• create a new HtmlDocument
• loadhtml
• use DOM navigation or an xpath query (SelectSingleNode etc) to find the elements
• access InerHtml of the elements you want

的API是类似XmlDocument的，但它适用于HTML不是XHTML。

The API is similar to XmlDocument, but it works on html that isn't xhtml.
