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=newDOMDocument();

$doc->load('books.xml');

$books=$doc->getElementsByTagName("book");

foreach($booksas$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";

}

?>

<?xmlversionxmlversion="1.0"?>

<books>

<book>
