php基于dom实现读取图书xml格式数据的方法

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 "; } ?>

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
