How to extract text from HTML using htmlagilitypack for this sample?
I wanna extract the text from a HTML source. I'm try开发者_C百科ing with c# and htmlagilitypack dll.
The source is:
<table>
<tr>
<td class="title">
<a onclick="func1">Here 2</a>
</td>
<td class="arrow">
<img src="src1" width="9" height="8" alt="Down">
</td>
<td class="percent">
<span>39%</span>
</td>
<td class="title">
<a onclick="func2">Here 1</a>
</td>
<td class="arrow">
<img src="func3" width="9" height="8" alt="Up">
</td>
<td class="percent">
<span>263%</span>
</td>
</tr>
</table>
How can I get the text Here 1 and Here 2 from the table?
HtmlDocument htmlDoc = new HtmlDocument();
htmlDoc.LoadHtml("web page string");
var xyz = from x in htmlDoc.DocumentNode.DescendantNodes()
where x.Name == "td" && x.Attributes.Contains("class")
where x.Attributes["class"].Value == "title"
select x.InnerText;
not so pretty but should work
Xpath version
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(t);
//this simply works because InnerText is iterative for all child nodes
HtmlNodeCollection nodes = doc.DocumentNode.SelectNodes("//td[@class='title']");
//but to be more accurate you can use the next line instead
//HtmlNodeCollection nodes = doc.DocumentNode.SelectNodes("//td[@class='title']/a");
string result;
foreach (HtmlNode item in nodes)
result += item.InnerText;
and for the LINQ version just change the var Nodes = .. line with:
var Nodes = from x in htmlDoc.DocumentNode.DescendantNodes()
where x.Name == "td" && x.Attributes["class"].Value == "title"
select x.InnerText;
