本文实例讲述了php基于dom实现读取图书xml格式数据的方法。分享给大家供大家参考，具体如下：
<?php
$doc = new domdocument();
$doc->load( 'books.xml' );
$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 - $publisher\n";
}
?>
books.xml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
希望本文所述对大家php程序设计有所帮助。
