EZ XML

Wednesday 22 January 2003 1:10:19 pm

Does anyone know how to use eZ XML to load information from an XML file into an eZ Publish template? The SDK examples show the use of eZ XML in a php file, but I don't think php will work in a .tpl file. I tried to use the SDK example in template, but it doesn't seem to work. Here's what I put in a class edit template, both with and without the {literal} tags.

{literal}
<?php
include_once( "/lib/ezxml/classes/ezxml.php" );

$xml = new eZXML();
$testDoc = "<?xml version='1.0'?>
<doc>
<article>
<paragraph name='Introduction'>Paragraph contents</paragraph>
<paragraph name='Story'>Story paragraph contents</paragraph>
</article>
</doc>";

$dom =& $xml->domTree( $testDoc );

print( "<b>XML document to parse:</b><br>" );

print( nl2br( htmlspecialchars( $testDoc ) ) );

print( "<br><b>Results from parsing:</b><br>" );
$paragraphs =& $dom->elementsByName( "paragraph" );

foreach ( $paragraphs as $paragraph )
{
// get the name of the item, should be paragraph
print( "<br/>New " . $paragraph->name() . ":<br/>" );

// print the value of the name attribute
print( "Name: " . $paragraph->attributeValue( "name" ) . "<br/>" );
print( "Content: " . $paragraph->textContent() . "<br/>" );
}

?>
{/literal}

Thanks for any help,

Mike

We won't allow PHP code in the templates by default, however you could write a template function which executes whatever is present as it's children.

Another approach to this is to have an xmltree operator which generates the xml dom tree and returns it. That way it's possible to go trough the tree to get the data you need.

A third option is to have an XSLT operator which would transform the xml into html according to an xslt file.

The two last solutions might be included in the standard release in the future, but we cannot guarantee when it will happen (if it will happen).

That appears to be trivial, why not set $buf as a single variable in a template which surrounds this by <div ....> </div> ?

The usual way is to set template variables from the PHP before the template is executed.
$tpl->setVariable( "buf", $buf );

or you can create custom template functions and/or operators to do the work.

The fetch system can be used to execute functions in a class, see kernel/content/function_definitions.php for some examples.

Also the PHP operator defined in lib/eztemplate/classes/eztemplatephpoperator.php can be used to map php functions to template operators easily, create your own custom functions in PHP and map them with this class.
