PHP读取和编写XML_PHP

代码如下:

Jack Herrington

DOM读取 XML

代码如下:

<?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";
}
?>

用 DOM 编写 XML

代码如下:

<?php
$books = array();
$books [] = array(
'title' => 'PHP Hacks',
'author' => 'Jack Herrington',
);
$doc = new DOMDocument(); //创建dom对象
$doc->formatOutput = true;

$r = $doc->createElement( "books" );//创建标签
$doc->appendChild( $r ); //将$r标签，加入到xml格式中。

foreach( $books as $book )
{
$b = $doc->createElement( "book" ); //创建标签
$author = $doc->createElement( "author" );
$author->appendChild($doc->createTextNode( $book['author'] )); //给标签添加内容
$b->appendChild( $author ); //将子标签 加入父标签


$r->appendChild( $b ); //加入父标签中！
}

echo $doc->saveXML();
?>

以上就是这2段读取和编写XML的DOM代码了，小伙伴们了解了没，有什么疑问可以给我留言
