Grab all text from html with Html Agility Pack
Solution 1:
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);
}
Solution 2:
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.
Solution 3:
I was in the need of a solution that extracts all text but discards the content of script and style tags. I could not find it anywhere, but I came up with the following which suits my own needs:
StringBuilder sb = new StringBuilder();
IEnumerable<HtmlNode> nodes = doc.DocumentNode.Descendants().Where( n =>
n.NodeType == HtmlNodeType.Text &&
n.ParentNode.Name != "script" &&
n.ParentNode.Name != "style");
foreach (HtmlNode node in nodes) {
Console.WriteLine(node.InnerText);
