How to read field from XML config file

[morvy]

Hi,

I want to create a component for sidebar to list categories, that I've created in i18n Special Pages, and I would like to read it from one location, because number of categories can change in future so I want to maintain it in one place. Is it possible to read this information with some function already present in GS ? In XML, it's like this:

Code:

<item>
      <name><![CDATA[main_cat]]></name>
      <label><![CDATA[Category]]></label>
      <type><![CDATA[dropdown]]></type>
      <option><![CDATA[not set]]></option>
      <option><![CDATA[Model]]></option>
      <option><![CDATA[Engine]]></option>
      <option><![CDATA[Wheels]]></option>
    </item>

Thank you for any suggestions

getXML($file)

make sure your xml has a header
<?xml version="1.0" encoding="UTF-8"?>

eheh, that was easy

if somebody would be interested in future, here's an example:
(hardware is special page type, item[3] is the field with category custom field)

PHP Code:

$file = getXml(GSDATAOTHERPATH."/i18n_special_hardware.xml");
foreach($file->fields->item[3]->option as $option) {
    echo $option;
}

you can also use xpath for this
