XSLT in PHP 5.1.1

[d_l]

I am trying to get XSLT to work in PHP 5.1.1.

running phpinfo.php confirms .. dom, xml, and xsl extensions are all enabled (any other extensions needed for XSLT processing?)

.......................

Trying the examples directly from here .. Zend - XML in PHP5 - XSLT

articles.xml

<?xml version="1.0" encoding="iso-8859-1" ?> 
<articles> 
    <item>   

        <title>PHP Weekly: Issue # 172</title>   

        <link>http://www.zend.com/zend/week/week172.php</link>   

    </item>

        <link>http://www.zend.com/zend/tut/tut-hatwar3.php</link>   

    </item> 
</articles>

articles.xsl

<?xml version=1.0" encoding="iso-8859-1" ?> 
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
  <xsl:param name="titles" /> 
  <xsl:template match="/articles"> 
    <h2><xsl:value-of select="$titles" /></h2> 
    <xsl:for-each select=".//title"> 
      <h3><xsl:value-of select="." /></h3> 
    </xsl:for-each> 
  </xsl:template> 
</xsl:stylesheet> 

articles.php

<?php 

/* load the xml file and stylesheet as domdocuments */ 
$xsl = new DomDocument(); 
$xsl->load("articles.xsl"); 
$inputdom = new DomDocument(); 
$inputdom->load("articles.xml"); 

/* create the processor and import the stylesheet */ 
$proc = new XsltProcessor(); 
$xsl = $proc->importStylesheet($xsl); 
$proc->setParameter(null, "titles", "Titles"); 

/* transform and output the xml document */ 
$newdom = $proc->transformToDoc($inputdom); 
print $newdom->saveXML(); 

?> 

I am seeing this list of errors .. (long filepaths snipped out, all three files located in same folder) ..

• Warning: DOMDocument::load() [function.load]: String not started expecting ' or " in file:///C%3A/<snipped path>/articles.xsl, line: 1 in C:<snipped path>\articles.php on line 5

• Fatal error: Call to a member function saveXML() on a non-object in C:<snipped path>\articles.php on line 17

What am I missing in my configuration?

The XML declaration in the articles.xsl is messed up. So it cannot properly parse it, and it is causing a cascading error. All of those errors seem to be a result of it, but I'm not 100% sure.

Anyways, you've got:

<?xml version=1.0" encoding="iso-8859-1" ?>

And that should be:

<?xml version="1.0" encoding="iso-8859-1" ?>

Notice a missing ". Anyways just be careful when copying code from articles. It's not unusual for it to contain minor typos and errors.

Thanks for finding that error .. I'll remember to validate next time ..

for others reading about PHP5 + XLST, I found this other thread with example.

Actually it wasn't that hard to find since the DOM extension will usually have trouble loading an invalid file. The first PHP warning in the list of errors points right to it:

Warning: DOMDocument::load() [function.load]: String not started expecting ' or " in file:///C%3A/<snipped path>/articles.xsl, line: 1 in C:<snipped path>\articles.php on line 5

Just have to look to articles.xsl in or around line 1 to see what all the hubbub is about a missing ' or "

The 2nd warning also point right to it as well with the "Malformed declaration" warning.
