you can handle xml output as if a string file, then easily parse xml file
with preg_match / preg_match_all,

smt like this can do the job:

<?php
$str="<xml version bla
bla><price>somevaluehere</price><price>somevaluehere2</price><price>somevaluehere2</price>etc";

preg_match_all("/<price>([^<])*<\/price>/i", $str, $matches);
echo count($matches[0]);
for ($i=0; $i< count($matches[0]); $i++) {
echo '<br> + '.$matches[0][$i];
}
?>

but you'd better learn to handle xml files via xml parsers.
