functx:contains-word
Whether one string contains another, as a separate word
Description
The functx:contains-word function returns true if $word is contained in $arg as a separate word. It must be delimited by non-word characters or the beginning or end of $arg. It is case insensitive; it matches a word even if the case is different.
A “non-word character” is one that in Unicode belongs in either the Punctuation, Separators or Other category. Generally, most punctuation and white space are considered non-word characters, while letters and digits are word characters.
