我想从这个div收集所有标签,但不知道如何用xpath方法以最佳方式执行此操作
<div class="biz_info">
<h3><a href="/profil/78122/s%C3%B8rby-rehab/">Sørby Rehab</a></h3>
<table class="string_14">
<tbody>
<tr>
<td>Postadr.:</td>
<td class="tab_space">Rognerudveien 8 B, 0681 Oslo</td>
</tr>
<tr>
<td>Telefon:</td>
<td class="tab_space">928 70 700</td>
</tr>
<tr>
<td>Nettside:</td>
<td class="tab_space"><a href="http://www.sorby-rehab.no" target="_blank">www.sorby-rehab.no</a></td>
</tr>
</tbody>
</table>
</div>
今天我的代码看起来像这样(但非常糟糕):
HtmlDocument doc = new HtmlDocument();
doc.Load(new StringReader(result));
HtmlNode root = doc.DocumentNode;
List<string> anchorTags = new List<string>();
foreach (HtmlNode link in root.SelectNodes("//@class=biz_info"))
{
string att = link.OuterHtml;
anchorTags.Add(att);
}
xpath的专业人士可以帮助我吗?
答案 0 :(得分:0)
HtmlDocument html = new HtmlDocument();
html.Load(new StringReader(result));
var anchorTags = html.DocumentNode.SelectNodes("//div[@class='biz_info']//a")
.Select(a => a.OuterHtml)
.ToList();
这将为您提供锚标签html的列表。如果你只需要网址:
urls = html.DocumentNode.SelectNodes("//div[@class='biz_info']//a[@href!='']")
.Select(a => a.Attributes["href"].Value)
.ToList();
