PHP 4.1.1 XSLT - Unknown encoding

Anon

Hi list

I've tried to set up PHP 4.1.1 on Windows XP Pro with php_xslt.dll
I've done all the initial work (i think) and phpinfo() shows that XSLT support is enabled.

But when I try the script below found as an example, I get unknown encoding '' error in line 1.
I feel I have tried anything.

Please tell me what wrong with the snippet below or if I'm missing something in the php.ini

$xh = xslt_create();

$html = xslt_process($xh, "test.xml","test.xsl");
if ($html!=""){
print "SUCCESS, test.xml was transformed by test.xsl into result.xml";
print ", result.xml has the following contents\n \n";
echo $html;
}
else {
print "Sorry, transformation failed ";
}

xslt_free($xh);

Kind regards

Can you include the top 5 rows from your XML and XSLT files? It can be that there is nothing wrong about your PHP but with your XML.

Hi Andrin

Here's the top 5 lines you requested.

XML File

<?xml version="1.0" encoding="utf-8"?>

<book>

<title>Professional Php Programming (Programmer to Programmer)</title>

<text>This book has been authored by:</text>
<authors>

XSL File

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">

<xsl:template match="/">
<body>
<xsl:apply-templates/>
</body>
</xsl:template>

<xsl:template match="title">

I will send you the complete files if you need them.
btw. i've also tried including the files with no content (empty files) with the same result. its like the xslt_process function doesn't read the files correctly.

I look forward for your answar and thank you for you help.

Kind regards

Hey :-)

I thought first there could be an error in your xml and/or xsl file. But that was not the case :-)

I don´t know what version of PHP you are using but since 4.1 there are new things about XSLT and Sablotron.
I checked the manual: http://www.php.net/manual/en/function.xslt-process.php. It says that you should write like this:

<?php

// Allocate a new XSLT processor
$xh = xslt_create();

// Process the document
if (xslt_process($xh, 'sample.xml', 'sample.xsl', 'result.html')) {
print "SUCCESS, sample.xml was transformed by sample.xsl into result.html";
print ", result.xml has the following contents\n \n";
print "<pre>\n";
readfile('result.xml');
print "</pre>\n";
}
else {
print "Sorry, sample.xml could not be transformed by sample.xsl into";
print " result.xml the reason is that " . xslt_error($xh) . " and the ";
print "error code is " . xslt_errno($xh);
}

xslt_free($xh);

Notice the fourth argument in the function xslt_process()? :-)

If this not works try to switch encoding to ISO-8859-1 in both your xml and xsl file.

Maybe, maybe not the answer. Good luck

Oopps! :-)

I didn´t get that all right. Go to the url I provided (http://www.php.net/manual/en/function.xslt-process.php) and read for you self :-)

Hi Andrin

I seems that did not work, but i may have found out why.

In the example send to you the code was something like
if (xslt_process($xh, 'sample.xml', 'sample.xsl', 'result.html')) { ...

But if I use file paths like above PHP proceduces an error.. Can't find file in c:\php\

So my files are used like this
if (xslt_process($xh, 'http://something.com/sample.xml', 'http://something.com/sample.xsl'

This gives the Unknown encoding. It seems I have a problem with my configuration, since it doesn't use the current directory.
I a script is ran from say c:\apache\httpdocs\script.php using releative paths and the xml,xsl files is in the same folder then the script should use that path, but it don't.

So it works, but nok like I would like it to.

Any ideas about PHP.ini config problems

Anon

OK, i finally found a solution/ the error.

This is for anyone who has the same problem. I don't know if its my php configuration but it seems that when suing the readfile() function with relative paths it looks in the php root folder and if you specify a path it fails to read the content correctly´, hence unknown encoding.

So I rewrote my script using the fopen() instead. For this to work I put the content into variables and applied them to an argument array as shown below and now it works.

Kind regards

<?php
// $xml and $xsl contain the XML and XSL data

$arguments = array(
'/xml' => $xml,
'/xsl' => $xsl
);

// Allocate a new XSLT processor
$xh = xslt_create();

// Process the document
$result = xslt_process($xh, 'arg:/xml', 'arg:/xsl', NULL, $arguments);
if ($result) {
print "SUCCESS, sample.xml was transformed by sample.xsl into the \$result";
print " variable, the \$result variable has the following contents\n \n";
print "<pre>\n";
print $result;
print "</pre>\n";
}
else {
print "Sorry, sample.xml could not be transformed by sample.xsl into";
print " the \$result variable the reason is that " . xslt_error($xh) .
print " and the error code is " . xslt_errno($xh);
}
xslt_free($xh);
?>

If You want to use relative paths the set
something like
xslt_set_base($xh, "file://d:/webroot/xslt/");

But there is still a problem with other languages than english.
How do You make XSLT with encoding windows-1257 or ISO-8859-13 ?
