if (aTags != null)
                {
                    foreach (var aTag in aTags)
                    {
                        s += counter + ".  " + aTag.InnerText + "<br>";

                        if (aTag.InnerText == "Polac pineapple")
                        {

Answer 1

Can you be more precise?

You can use "id".

<span id="thisspan">A uniquely identifiable element.</span>

The id attribute provides a unique identifier for an element within the document. It may be used by an a element to create a hyperlink to this particular element.

The most important aspect of the id attribute is that it must be absolutely unique. Unlike the class attribute, which may apply the same value to many elements in a page, an id that’s applied to an element must not match an id used anywhere else on the same page.

The id attribute value must begin with a letter in the roman alphabet (a–z or A–Z); this can be followed by any combination of letters (a–z or A–Z), digits (0–9), hyphens (-), underscores (_), colons (:), and periods (.). The id value is case sensitive, thus This is me and This is me would be considered to be separate and uniquely identifiable elements on the same web page.
