Redirect page using xslt in sharepoint list pages

You can achieve this using the second solution which you have said.
What you need do is give the url value to the GenFireServerEvent method.
Before:
  {ddwrt:GenFireServerEvent('__commit;__redirect={/}')};
After:
  {ddwrt:GenFireServerEvent('__commit;__redirect={http://www.microsoft.com}')};

Note: If you change like his, you will receive a
warning message  like this: “You are about to be redirected to a new internet site.” Of course, if the target url is in the same site  with the page, you will not receive the warning message.

Hope it’s helpful.
