This article describes the method of reading xml format data in PHP based on DOM. Share it for your reference, as follows:

<?php
 $doc = new DOMDocument();
 $doc->load( '' );
 $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";
