I'm using apache mod_rewrite and I have the following RewriteCond and RewriteRule in my .htaccess file.I have more than 10 regular expressions in which I capture and convert to url parameters using mod_Rewrite.

RewriteCond %{REQUEST_URI} ^/([^/]*)/([^/]*)/? .....//continue for more than 10 expressions...

RewriteRule .* index.php?par1=%1&par2=%2&par3=%3 ..... par10=%10

But the problem is,for the 10th url parameter for example,the value will not match the 10th expression value but the 1st expression value with a following 0.
%10 = %1 + 0
%11 = %1 + 1
%12 = %1 + 2
.
.
But I want to have the 10th,11th,... expression values.

What should I do?I couldn't find any solution to this issue.I appreciate if anyone could help me with this issue.
Thanks in advance.

UPDATE:
I've read from the apache documentation that backreferences for both RewriteRule($N) & RewriteCond(%N) are between 0 and 9.
I found out that recursion would be useful in this case but I don't know(and couldn't find out)how.
