Validator plugin

You do not have to use the W3C Validator to check HTML and co. for validity. You can do it offline, and that standalone as well as from within phase 5.

Our Validator plugin in action.

version history


  1. Download OpenSP, the SGML parser that is used by the W3C, and unzip it into a directory of your choice.
  2. Unzip recent SGML libraries from the W3C into a directory of your choice.
  3. From validator.zip unzip the files Validator.exe and validator.ini into the plugins directory of phase 5. If you use the plugin standalone, just pick any folder you want.
  4. In validator.ini change the paths to onsgmls.exe and to the directory where the SGML libraries reside and start work.
  5. in addition you can put a link to validator.exe on the desktop or into your SendTo folder.


Simply open a file in phase 5 and choose Validator from the Tools menu. Alternatively, you can create a shortcut, e.g. on your desktop, and validate files via drag and drop.

If you have a link on your desktop you can validate files via drag and drop, a link in SendTo can be reached via Send To... in the context menu of any file.
