HTMLAgilityPack iterate all text nodes only

三世轮回 提交于 2019-11-30 15:19:39

Something like this:

    HtmlDocument doc = new HtmlDocument();
    doc.Load(yourHtmlFile);

    foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//text()[normalize-space(.) != '']"))
    {
        Console.WriteLine(node.InnerText.Trim());
    }

Will output this:

Select your Age:
0 to 10
20 and above
Help/Hints:
This is required field.
Make sure select the right age.

I tested @Simon Mourier's answer on the Google home page and got lots of CSS and Javascript, so I added an extra filter to remove it:

    public string getBodyText(string html)
    {
        string str = "";

        HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
        doc.LoadHtml(html);

        try
        {
            // Remove script & style nodes
            doc.DocumentNode.Descendants().Where( n => n.Name == "script" || n.Name == "style" ).ToList().ForEach(n => n.Remove());

            // Simon Mourier's Answer
            foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//text()[normalize-space(.) != '']"))
            {
                str += node.InnerText.Trim() + " ";
            }
        }
        catch (Exception)
        {
        }

        return str;
    }
