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.)
