Incorrect URL Construction, need HTAccess Redirect Fix

Question

I've made a huge mistake in my shop when creating pagination links. After the .html, instead of a question mark my code just appended an ampersand. Now Google Webmaster tools is throwing up hundreds of 404's.

I know how to fix the problem on a URL by URL basis, but is there a wildcard solution as a first off sanity check in HTAccess to check for ".html&" and replace with ".html?"?

Below are examples of my issue, myitemspage represents a category of items, so i have over 50 categories:

http://www.domain.com/myitemspage.html&page=1&limitchange=10
http://www.domain.com/myitemspage.html&page=1&limitchange=25
http://www.domain.com/myitemspage.html&page=1&limitchange=50
http://www.domain.com/myitemspage.html&page=1&limitchange=100

Thank you for any help on my self-created nightmare,

Mark.

Try:

RedirectMatch 301 ^(.*)\.html&(.*)$ /$1.html?$2

or using mod_rewrite:

RewriteEngine On
RewriteCond %{QUERY_STRING} ^$
RewriteRule ^(.*)\.html&(.*)$ /$1.html?$2 [L,R=301]

in the htaccess file in your document root.
