Re: [TCLUG:18438] regex for stripping FONT tags?

[barnabas@pobox.com]

You might try undefining the input record seperator, $/ (IIRC) or
$INPUT_RECORD_SEPARATOR if you're use-ing English.  This will cause the
entire file to be read into a single string and should allow you to use
the regex below to get rid of <font> tags that cross new lines.
