HTMLAgilityPack parse in the InnerHTML

问题:

<div>
<b>Token1</b>
Token2
<b>Token3</b>
</div>

I try to extract Token2 from the div

I manage to get Token1 and Token3 with :

HtmlNodeCollection headerFooter = doc.DocumentNode.SelectNodes("//div//b");

How can I extract directly Token2 with HTMLAgilityPack ?

One dirty option is to replace Token1 and Token2 by string.empty in doc.DocumentNode.SelectNodes("//div").InnerText, but I imagine it can been done in more clean way with HTMLAgilityPack...

回答1:

The text is in the text nodes; so you should be able to look at "//div/text()" and concatenate:

StringBuilder sb = new StringBuilder();
foreach (HtmlAgilityPack.HtmlTextNode node in
      doc.DocumentNode.SelectNodes("//div/text()"))
{
    sb.Append(node.Text.Trim());
}
string s = sb.ToString();
