导语：PHP如何基于dom实现图书xml格式数据呢？下面是小编给大家提供的代码实现方法，大家可以参考阅读，更多详情请关注应届毕业生考试网。
<?php
$doc = new DOMDocument();
$doc->load( '' );
$books = $doc->getElementsByTagName( "book" );
foreach( $books as $book )
{
$authors = $book->getElementsByTagName( "author" );
$author = $authors->item(0)->nodeValue;
$publishers = $book->getElementsByTagName( "publisher" );
$publisher = $publishers->item(0)->nodeValue;
$titles = $book->getElementsByTagName( "title" );
$title = $titles->item(0)->nodeValue;
echo "$title - $author - $publishern";
}
?>
文件如下：
<?xml version="1.0"?>
<books>
<book>
<author>Jack Herrington</author>
<title>PHP Hacks</title>
<publisher>O'Reilly</publisher>
</book>
<book>
<author>Jack Herrington</author>
<title>Podcasting Hacks</title>
<publisher>O'Reilly</publisher>
</book>
</books>
运行结果如下：
PHP Hacks - Jack Herrington - O'Reilly
Podcasting Hacks - Jack Herrington - O'Reilly
