英文:
How can I read a web page with Html Agility Pack
问题
我想通过这个库来读取一个网页，但是有些页面有一个脚本，首先运行脚本（例如欢迎页面或者加载页面等），然后在第二级显示页面内容。而在这个页面中，这个库只能访问到第一级。
string linkUrl = "yoursite.come";
var doc = new HtmlWeb().Load(linkUrl);
var pTags = doc.DocumentNode.Descendants("p").Select(el => el.InnerText)
.Where(u => !String.IsNullOrEmpty(u.ToString()));
// 有关pTags的任何代码
英文:
I want to read a web page by this library but some page has a script that in first level run script ( for example Welcome or site is loading or … ) then in second level show page content.
And in this page this library I access just the first level.
string linkUrl = "yoursite.come";
var doc = new HtmlWeb().Load(linkUrl);
var pTags = doc.DocumentNode.Descendants("p").Select(el => el.InnerText)
.Where(u => !String.IsNullOrEmpty(u.ToString()));
// Any Code about pTags
