you should use the simplexml XML parser and some regular expression.

你应该使用simplexml XML解析器和一些正则表达式。

<?php
$string = <<<XML
<?xml version='1.0'?>
<document>
    <description>1 macbook air and 4 ipods</description>
</document>
XML;
$xml = simplexml_load_string($string);
$description = $xml->description;
preg_match('|(\d+) macbook air and (\d+) ipods|', $description, $match);

print_r($match[1] . ' ');
print_r($match[2]);
