導(dǎo)語：php如何基于dom實現(xiàn)圖書xml格式數(shù)據(jù)呢？下面是小編給大家提供的代碼實現(xiàn)方法，大家可以參考閱讀，更多詳情請關(guān)注應(yīng)屆畢業(yè)生考試網(wǎng)。
<?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>
