php基于dom实现读取图书xml格式数据的方法

 $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 - $publishern";

 }
