up to date exchange rates) to work with http://www.bank.lv/vk/xml.xml Not

Just a personal thought... You drop a couple hundred lines of code and
don't even bother explaining what is failing... It looks like you are
not looking for help or advise but for someone who'll do the job for you
for free.

no, absolutely. This is small enough code. What not work? After I replaced
feed with http://www.bank.lv/vk/xml.xml , and changed other strings as
follows:
$xml = simplexml_load_file('http://www.bank.lv/vk/xml.xml');
$xmlString = $xml->asXML();
$pos = stripos($xmlString,"<Currency=");
$xmlString = substr($xmlString,$pos);
$pos2 = stripos($xmlString,"</CRates>");
$xmlString = substr($xmlString,0,$pos2);
$arr = explode("<CRates ",$xmlString);
saved as html page when tested it - show just form with drop down selectors
with no values inside, and "convert" action not work also.
Thanks.
