问题描述

我正在使用HAP库来解析HTML: http://html-agility-pack.net

I'm using the HAP library to parse HTML: http://html-agility-pack.net

我基本上只想从所有img标记中检索src值.

I basically just want to retrieve the src value from all the img tags.

我已经尝试了好几件事，但是我似乎做不到！

I've tried several thing but I can't seem to do it!

推荐答案

在示例页面中进行了修改:

Modified from the examples page:

HtmlDocument doc = new HtmlDocument();
doc.Load("file.htm"); //or whatever HTML file you have
HtmlNodeCollection imgs = doc.DocumentNode.SelectNodes("//img[@src]");
if (imgs == null)
   return;
foreach (HtmlNode img in imgs)
{
   if (img.Attributes["src"] == null)
      continue;
   HtmlAttribute src = img.Attributes["src"];
   //Do something with src.Value
}
