The tagcount( function counts the number of times a specified tag (usually an HTML tag) appears in the text. See Tag Parsing for more information on HTML tags.

Parameters

This function has three parameters:

text – is the item of text that contains the tags you want to count.

header – is the text that you want to use as a tag header. For example, if you want to count HTML tags, use `"<"` as the header. If you wanted to count bold text items you would use `"<B>"` as the header. (Note: Upper or lower case is ignored, so `"<b>"` will also work.)

trailer – is the text that you want to use as a tag trailer. For example, if you want to count HTML tags, use `">"` as the trailer. If you wanted to count bold text items you would use`"</B>"` as the trailer. (Note: Upper or lower case is ignored, so `"</b>"` will also work.)
