[2004-10-22 21:13 UTC] csg at diatom dot de

Description:
------------
I had downloaded today XML_Transformer-1.0.1.tgz and have
played with it - but no example did produce any output if
class XML_Transformer_Namespace_Image was involved.

Neither code published in iX (http://www.heise.de/ix/
artikel/2003/12/124/ especially Listings 2 and 4) nor the
example code in file Transformer/Namespace.php.
(In the latter case I could fix the problem while replacing
XML_Transformer::attributesToString($this->imageAttributes)
with
XML_Util::attributesToString($this->imageAttributes)
)

Note:
Caused by "Safe mode" restrictions I had to install the
PEAR packages XML_Transformer-1.0.1.tgz and
XML_Util-0.6.1.tgz manually as described in the PEAR
manual.

Output of phpinfo() is available at http://www.diatom.de/
test.php .

Reproduce code:
---------------
One of several examples with the problem above is listet here:
<?php
error_reporting(E_ALL);
ini_set( 'include_path', '/var/httpd/web1/pearIncludes/' . PATH_SEPARATOR . ini_get('include_path') );

require_once 'XML/Transformer.php';
require_once 'XML/Transformer/Namespace/Image.php';

$t = new XML_Transformer(
array(
'debug' => true,
'overloadedNamespaces' => array(
'img' => new XML_Transformer_Namespace_Image
)
)
);
$t->transform('<img:img src="test.png" />');
?>

Expected result:
----------------
Image with width and height attributes, e,g,:

<img src="test.png" width="256" height="256" />

Actual result:
--------------
really nothing - empty result page (even in source view).

The code example is not quite right - it does miss an
"echo $t" instruction at the end. (I'm sorry for that -
the example was originally based on an "OutputBuffer" one
and there is no need for the echo instruction.)
Inserting this missed instruction behaviour does change:
Now entire output consists of word "Object":
http://www.diatom.de/testXmlTransformerImage.php

However, expected output would be an extended image tag,
too, e.g. <img ...

(Note: Beside of using XML_Transformer_Namespace_Image,
over time XML_Transformer does a good job for me. Thanks
for writing it!)
