Well, in this case, you'd have to use regular expressions. One way to do it
would be:
$SanitizedString =
ereg_replace('<[[:space:]]*([[:alnum:]]+)[^>]*>', "<\\1>", $String);
this _should_ work (haven't tested it). If you wanted to remove some tags
entirely, and then remove the attributes of the remaining tags, you could
(1) use strip_tags() with a list of allowable tags, then (2) run the regexp
above. Incidentally, the above regexp also removes leading spaces from the
tag. Eg, < font style="unreadable"> becomes <font>. If you don't want,
that user the regexp
'<([[:space:]]*[[:alnum:]]+)[^>]*>'
instead.
