Can someone please help me to modify this sanitizer function for Google Base Feeder?

I've been tinkering around with the code a bit to try to get it to work the way I want but need some advice about the regular expressions.

The way the Google Base Feeder is now, all & and " gets stripped out of the XML file. I entered the & and " as & and " when I created the product listings. I don't know if ZC changes it to & and ". Anyway, the Feed creator strips them out and I would like to leave them in the title and descriptions.

Here is the zen_xml_sanitizer function:

 function zen_xml_sanitizer ($str) {
  $_strip_search = array("![\t ]+$|^[\t ]+!m",'%[\r\n]+%m'); // remove CRs and newlines
  $_strip_replace = array('',' ');
  $_cleaner_array = array(">" => "> ", "®" => "", "®" => "", "™" => "", "™" => "", "\t" => "", "    " => "");
  $str = html_entity_decode($str);
  $str = strtr($str, $_cleaner_array);
  $str = preg_replace($_strip_search, $_strip_replace, $str);
  $str = strip_tags($str);
  $str = eregi_replace("[^[:alnum:][:space:].,!()'-_/+=?]", "", $str);
  $str = htmlentities($str);
  $str = str_replace('&', '&', $str);
  return $str;
 }

What needs to be changed to leave " alone, it doesn't affect the XML file, and change the & to &? I'm almost there but not quite!:huh:

Thanks!

I've been trying to figure it out but I am still not getting it.

Can anyone please help me figure out this function? My main problem is that it strips out all double quotes from the titles and leaves & instead of changing it to & in the descriptions

Please help.......:frusty:
