在PHP语言中我们可以用以下方法取得我们想要的值：

<?php
$xmldata = simplexml_load_file("iciba.xml");

header("Content-Type: text/html; charset=UTF-8");
print_r($xmldata); //第一部分www.111com.net

$listcount = count($xmldata->sent);

for($i=0;$i $dictlist = $xmldata->sent[$i];
echo "
例句：".$dictlist->orig;
echo "
翻译：".$dictlist->trans;
}
?>“第一部分”将输出：

SimpleXMLElement Object
