Here's what I did that seems to work....


I'm going to loop thru a DS of data and for each row write out a line to an HTML file, as in:

<a href="#product#">A6153AR</a>

or

<a href="#part#">A6171-69001</a>

Then I have the following C# code:

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    HtmlElementCollection tags = webBrowser1.Document.Links;

    foreach(HtmlElement element in tags)
    {
        element.Click += new HtmlElementEventHandler(element_Click);
    }

}

void element_Click(object sender, HtmlElementEventArgs e)
{
    HtmlElement x = (HtmlElement)sender;

    string sId = x.InnerText;
    string sSection = x.OuterHtml;
    sSection = sSection.Replace("\"", "");

    char chSep = '#';
    string[] arrStr = sSection.Split(chSep);

    sSection = arrStr[1];

    LinkClicked(sSection, sId);

}

private void LinkClicked(string sSection, string sLinkText)
{
    switch (sSection.ToLower())
    {
        case "navigation":
            break;

        case "part":
            break;

        case "product":
            break;

    }
}

>>That's exactly the problem. There's nothing unique about the data. For example, a product number might be "A6153AR" and a part number might be "A4926A" or "A6153-10005". How would you know that the first is a product and the other two are parts?

>Do you control the code which generates the HTML? If so, just change the URL based on which link you're rendering. If you don't control this, about all you can do is compare a product link and a part link. If there literally is no difference except for the number (and they look identical to one another) you're out of luck.
