XML Parsing Class (Rated 4.5)Description:
Quick and dirty XML parsing class, as used at OxyScripts.com to parse the news feeds from other sites. It works as it should, although the coding is dirty. It seems to run quite quickly too ! Code starts here
<?php
/* USAGE
$parser = new parser;
$fp = $parser->getXML("http://www.domain.com/file.xml", "file.xml");
while ($data = fread($fp, 4096)) {
$parser->parse($data);
}
$parser->close();
*/
