.HTACCESS Rewrite Rule 301

Hi,

I have various hundred URL's that have been indexed in google and I need to resolve them and redirect them. The pattern is like this:

www.mydomain.com/en/decor/somefolder-1/somepage-1.html?p=4
www.mydomain.com/it/somepage-1.html
www.mydomain.com/es/somefolder/anotherfolder-1/somepage.html

The CMS I use, Magento, has a rewrite module that fails sometimes and adds -1 to folders and to .html files.

As you can see, I would need a rewrite rule that would take off the -1 for the folders and the -1 just before the .html for pages.

I would need it to 301 the incoming requests based on above and rewrite them to:

www.mydomain.com/en/decor/somefolder/somepage.html?p=4
www.mydomain.com/it/somepage.html
www.mydomain.com/es/somefolder/anotherfolder/somepage.html

Your help is greatly appreciated.

thanks!
