Html Agility Pack extracts every text from html.

c# html-agility-pack

Question

Input

<html><body><p>foo <a href='http://www.example.com'>bar</a> baz</p></body></html>

Output

foo
bar
baz

I know of htmldoc.DocumentNode.InnerText, but it will give foobarbaz - I want to get each text, not all at a time.

Accepted Answer

var root = doc.DocumentNode;
var sb = new StringBuilder();
foreach (var node in root.DescendantNodesAndSelf())
{
    if (!node.HasChildNodes)
    {
        string text = node.InnerText;
        if (!string.IsNullOrEmpty(text))
            sb.AppendLine(text.Trim());
    }
}

This does what you need, but I am not sure if this is the best way. Maybe you should iterate through something other than DescendantNodesAndSelf for optimal performance.

XPATH is your friend :)

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(@"<html><body><p>foo <a href='http://www.example.com'>bar</a> baz</p></body></html>");

foreach(HtmlNode node in doc.DocumentNode.SelectNodes("//text()"))
{
    Console.WriteLine("text=" + node.InnerText);
}
