利用php访问上篇BOOKSTORE.xml中bookname标签内容

<?php

$newxml = new DOMDocument("1.0","utf-8");//创建dom对象

$xml_file = 'example.xml';

$newxml->load($xml_file);//加载文件

$book = $newxml->getElementsByTagName("book")->item(0);

$bookname = $book->getElementsByTagName("bookname")->item(0)->nodeValue;

var_dump($bookname);
