带有curl的php解析器xml，只显示我想要的标记

可能重复：

我有一个Php/curl文件

<?php
echo "Conversion Stats<br />"; 

$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_URL,'http://login.leadkitchen.com/affiliates/api/4/reports.asmx/Conversions' );
$post_array = array(
       'affiliate_id' => '123',
    'api_key' => 'abc',
    'start_date' => '10/8/2012',
    'end_date' => '10/11/2012',
    'offer_id' => '123',
    'start_at_row' => '1',
    'row_limit' => '0',
    'sub_affiliate' => 'email'
);

//url-ify the data
foreach($post_array as $key=>$value) 
{ 
    $post_array_string .= $key.'='.$value.'&'; 
}
$post_array_string = rtrim($post_array_string,'&');
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_POST,count($post_array ));
curl_setopt($ch,CURLOPT_POSTFIELDS,$post_array_string);
$response = curl_exec($ch);



print "$response";


?>

以及对此可能的XML响应

我实际上只需要在页面中显示转换id和价格。我不想在页面上显示其他结果。我该怎么做

您可以使用

simplexmlement

获取所需的元素

$xml = new SimpleXMLElement($response);
echo "<pre>";
echo $xml->conversions->conversion->conversion_id, PHP_EOL;
echo $xml->conversions->conversion->price, PHP_EOL;
