Question

HTML:

<strong>Capture Date/Time:</strong> August 1, 2012 1:05:00 PM EST<br>
<strong>Instructor:</strong> Ash<br>
<strong>Instructor Email:</strong> [e-mail]<br>
<strong>Course ID:</strong> Course321<br>

How would I go about getting the text on the right of each strong node?

For example, to get the course ID so I ended up with a string of “Course321”.

Code:

private string getCourseID()
{
    foreach (HtmlAgilityPack.HtmlNode strong in htmlDoc.DocumentNode.SelectNodes("//strong"))
    {
        string innerText = strong.InnerText;

        if (innerText.Contains("Course ID"))
        {
            //select the outer text
            //return outertext;
        }
    }
}

Current Code:

private string getCourseID()
{
    HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlAgilityPack.HtmlDocument();

    string value = "Error";

    foreach (HtmlAgilityPack.HtmlNode strong in htmlDoc.DocumentNode.SelectNodes("//strong"))
    {
        string innerText = strong.InnerText;

        if (innerText.Contains("Course ID"))
        {
            HtmlAgilityPack.HtmlNode sibling = strong.SelectSingleNode("following-sibling::text()");

            value = sibling.InnerText.Trim();

            MessageBox.Show(value);
        }
    }

    return value;
}

Using the following-sibling::* XPath axis:

HtmlNode sibling = strong.SelectSingleNode("following-sibling::text()");
Console.WriteLine("Course ID = " + sibling.InnerText.Trim());
