Parsing and Extracting Text from ePub XHTML

[Mark Schonewille]

Hi Brahmanathaswami,

This works on LC 6.7.3:

on mouseUp
      put fld 1 into x
      if the platform is not "MacOS" then
           // not sure why this works
           put isoToMac(x) into x
      end if
      put uniDecode(uniEncode(x,"UTF8")) into x
      set the htmlText of fld 2 to x
end mouseUp

--
Best regards,

Mark Schonewille
