解析xml以获取一些值

Question

http://www.managerleague.com/export_data.pl?data=transfers&output=xml&hide_header=0

These are player sales from a browser game. I want to save some fields from these sales. I am fetching that xml with curl and storing on my server. Then do the following:

$xml_str = file_get_contents('salespage.xml');
$xml = new SimpleXMLElement($xml_str);
$items = $xml->xpath('*/transfer');

print_r($items);

foreach($items as $item) {
    echo $item['buyerTeamname'], ': ', $item['sellerTeamname'], "
";
}

The array is empty and i cant seem to get anything from it. What am i doing wrong?

You forgot a slash in your xpath:

$xml_str = file_get_contents('salespage.xml');
$xml = new SimpleXMLElement($xml_str);
$items = $xml->xpath('/*/transfer');

print_r($items);

foreach($items as $item) {
    echo $item->buyerTeamname, ': ', $item->sellerTeamname, "
";
}
