Extract text from HTML. Excludes content from metadata tags by default.
For example, script and style. Reduces multiple spaces to a single space
and trims whitespace from the start and end by default. Set preserveWhitespace
to true to disable this behavior. Optionally, replace tags with text.
Offers a much nicer out-of-the-box experience compared to striptags. See comparison here.
