我正在使用scorm测验，可以将数据作为xml导出到我的服务器。我正在尝试解析该数据，以便我可以使用其中的一些来发送php电子邮件。我现在正在尝试的是返回数字1，我无法弄清楚如何使其工作。帮助
<?php
$version = $_POST['v'];
$points = $_POST['sp'];
$passing_percent = $_POST['psp'];
$gained_score = $_POST['tp'];
$username = $_POST['sn'];
$email = $_POST['se'];
$quiz_title = $_POST['qt'];
$detailed_results_xml = $_POST['dr'];
$xml_string = <<<_XML
print "<?xml version="1.0" encoding="iso-8859-1"?>" . $detailed_results_xml;
_XML;
$xml = simplexml_load_string($xml_string);
$emailtest = print_r($xml);
mail("email@email.com",$quiz_title,$emailtest,"From: fromname <noreply@test.com>");
?>
如果我将$ detailed_results_xml通过电子邮件发给自己，就会发出这样的结论：

<direction>Exercise 2:!
Regulate the Body’s Clock through Daily Routine
Some people use a morning routine to help them wake up and a bedtime routine of relaxing activities to prepare their bodies for sleep. These activities of daily living act as “cues†to signal the brain to fall into biological rhythms.
In this exercise, consider for a minute what you did last night before bed and what you’ve done so far today.
Take a moment to describe your daily routine and activities starting with last night.

很抱歉，如果格式在xml位上搞砸了，但你应该从中得到这个想法。所以xml位是由$ detailed_results_xml生成的，我需要将其中的一些部分解析为html以通过电子邮件发送，但是现在我只看到一个数字1.非常感谢任何帮助！
