Sablotron Support

abelajohnb

Hello.

I have been assigned a task which I know nothing about. (hey, isn't that what work is all about!)

I was told to find some documentation on why Sablotron would not parse XML files with XSL.

It all might was well be a foreign-language to me...

So, I pose the question...

Does a web site exist where one can find some support for Sablotron?
(other than their home page... which doesn't have any support to speak of)

Many, many, thanks!

post some details or even some general info about the problems you are having. if you post the error message(s) you are getting, you will probably be able to get some very detailed feedback.

useful info:

operating system
web server software
php version
error msgs
example code

We are dynamically generating XML out of data in a MySQL db.

Then we are tranforming it with XSL using the Sablontron processor.

Sometimes it doesn't parse, but doesn't tell us why.

We need to find out what our errors are on our XSL processor.

Are there any ways to find that out?

Thanks.

on 1-17-01, some changes were made in cvs that improve error reporting in the sablotron module. you can download the latest snapshot at http://snaps.php.net.
( the changes may have made it into php4.0.4pl1 but i am not sure. check the changelog)

also, can you elaborate on what you mean by "doesn't parse"?

nothing happens?
you get an error msg?
other?

i get the most verbose error reporting in my apache error log. any problems in your xml or xslt will be reported there... and i can tell you this: for me, the problem is almost always a well-formedness error in the xslt stylesheet 😉

Our XML just comes through untransformed.

maybe you should post the code that you are using to do the transformation.

Our XML is valid, but the below XSL is bombing.

(thanks for the help!)

Here is the file:

<?php
//- Header( "Content-type: text/xml");
include "../classes/site_functions.php";
include "./include/config.php";
$connection = getMysqlDBConnection($host, $user, $passwd, $db_name);
?>

<?php

$path2XSL ="/home/www/cms_xml/feelrite/xsl/";

if (isset($ADMIN)){
$catalogXSL = "catalogADMIN.xsl";
} else {
$catalogXSL = "category.xsl";
}

include $class_path . "/catalog_include.php";

if ($category != "") {
$catalog = new catalog($category, $connection);

$catalogxml = $catalog->pullXML('0', $connection);
$finalXML .= '<?xml version="1.0" encoding="UTF-8"?>' . "\n";
$finalXML .= "<ROOT>\n";
$finalXML .= $catalogxml;
$finalXML .= "</ROOT>\n";

if ($finalXML != "") {
xslt_output_begintransform($path2XSL . $catalogXSL);
print $finalXML;
xslt_output_endtransform();
}

}
?>

c'mon now! you gotta read the docs at least!

first off, you are never giving your xml string to the parser! anywhere!

secondly, you are printing this un-parsed xml string to the screen, so of course all you are getting is xml!

replace this:

xslt_output_begintransform($path2XSL . $catalogXSL);
print $finalXML;
xslt_output_endtransform();

with this:

if (xslt_process($path2XSL . $catalogXSL, $catalogxml, $result)){
echo $result;
}else{
echo "There was an error that occurred in the XSL transformation...\n";
echo "\tError number: " . xslt_errno() . "\n";
echo "\tError string: " . xslt_error() . "\n";
exit;
}

Hello.

Actually, everything is getting passed through.

All is working on all of our files (except for one).

Anyway.... we threw in the code you suggested and we got:

There was an error that occurred in the XSL transformation... Error number: 2 Error string: OK

Any idea what the heck that means??

Thanks!

oops, i'm not familiar w/ the begin/end_transform functions. i always have used xslt_process() or xslt_transform().
sorry 😉

<sarcasm>
and that error msg was real helpful! thanks sablotron!
</sarcasm>

2 things:

have you looked at your apache error log?
get those xslt error reporting functions that were in the code sample i gave you, and insert them in your code, and see what it reports.

general comment:

the fact that most of your transformations work and some don't, seems to point the finger at the xml data. apache logs will tell you if it is no well formed or has illegal characters.
