No, it's that you put the parens () around only the .* and not around
what you wanted:
ereg("<route name='$to' x='\\.\\.(.*/in') rec='.*' />", ...

You may want to consider a couple actions:
Switch to PCRE http://php.net/pcre
It's better documented, less confusing, faster, and just better all

Download and play around with "The Regex Coach" which provides a
visual feedback on what happens when you change the #$^%& inside your
pattern.

I haven't used ereg in so long, I can't answer this for ereg.
In PCRE, you use tack on 'U' after your end patter delimiter.
