什麼是 XML?
DOM讀取 XML
用 DOM 編寫 XML
XML 是一種數據存儲格式。它沒有定義保存什麼數據,也沒有定義數據的格式。XML 只是定義了標記和這些標記的屬性。格式良好的 XML 標記看起來像這樣:
<name>Jack Herrington</name>
<?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"; } ?>
<?php $books = array(); $books [] = array( 'title' => 'PHP Hacks', 'author' => 'Jack Herrington', ); $doc = new DOMDocument(); //創建dom對象 $doc->formatOutput = true; $r = $doc->createElement( "books" );//創建標簽 $doc->appendChild( $r ); //將$r標簽,加入到xml格式中。 foreach( $books as $book ) { $b = $doc->createElement( "book" ); //創建標簽 $author = $doc->createElement( "author" ); $author->appendChild($doc->createTextNode( $book['author'] )); //給標簽添加內容 $b->appendChild( $author ); //將子標簽 加入父標簽 $r->appendChild( $b ); //加入父標簽中! } echo $doc->saveXML(); ?>
