问题描述
我正在尝试从网页中的特定div获取图像标记。这是网页链接链接
我用过这段代码:
I am trying to fetch images tags from a specific div in a web page. Here is the web page link link
I have used this code:
var webGet = new HtmlWeb();
var document = webGet.Load(txt.Text);
var infos = from info in document.DocumentNode.SelectNodes("//div[@class='ui-box-body']")
from link in info.SelectNodes("img").Where(x => x.Attributes.Contains("src"))
select new
{
LinkURL = link.Attributes["src"].Value
};
lbl.Text = infos.ToString();
但它返回null值。请告诉我这段代码有什么不对。在此先感谢
but it returns null value. Please tell me whats wrong in this code. Thanks in advance
推荐答案
HtmlWeb web = new HtmlWeb();
HtmlAgilityPack.HtmlDocument document = web.Load(url);
var rateNode =来自document.DocumentNode.SelectNodes中的信息(// div [@ class ='class name'])
来自info.SelectNodes中的链接(/ /img\").Where(x=>x.Attributes.Contains(\"src))
选择新的
{
link .Attributes [src]。价值
};
//返回查看(lstRecords);
字符串结果;
lbl.Text = rateNode.ToString();
foreach(var a in rateNode)
{
int count = 0;
Image img = new Image();
img.ID = count +a;
count ++;
img.ImageUrl = a .Value
Controls.Add(img);
}
HtmlWeb web = new HtmlWeb();
HtmlAgilityPack.HtmlDocument document = web.Load(url);
var rateNode = from info in document.DocumentNode.SelectNodes("//div[@class='class name']")
from link in info.SelectNodes("//img").Where(x=>x.Attributes.Contains("src"))
select new
{
link.Attributes["src"].Value
};
// return View(lstRecords);
string result;
lbl.Text = rateNode.ToString();
foreach (var a in rateNode)
{
int count=0;
Image img = new Image();
img.ID = count + "a";
count++;
img.ImageUrl = a.Value
Controls.Add(img);
}
