如何在PHP，DOM脚本中加载多个XML文档？

Question

I have two different XML structured documents, an XSLT that renames the elements and nodes of them to satisfy both and a PHP code that will save them into a new XML doc.

This is the code I used for testing purposes, however how can I load two or more paths like book1.xml and book2.xml into the $xml ? I know how to $dom->load( 'book1.xml' );

<?php

// create an XSLT processor and load the stylesheet as a DOM 
$xproc = new XsltProcessor();
$xslt = new DomDocument;
$xslt->load('stylesheet.xslt');    // this contains the code from above
$xproc->importStylesheet($xslt);


// your DOM or the source XML (copied from your question)
$xml = '';
$dom = new DomDocument;
$dom->loadXML($xml);


?>

Read about and use the standard XSLT function document().

In XSLT 2.0 there is also standard support for producing multiple result documents -- read about the <xsl:result-document> element.

If you are bound to XSLT 1.0, you cannot produce more than one result document in one transformation. You can either use extension libraries (EXSLT, the <exsl:document> extension element) or you can produce all results in one result document and then produce every single result out of it using another transformation, that you run once for producing each result.
