Magento：如何获取xtendo订单导出xsl模板的国家/地区名称

I am referring to Xtendo Order Export ext here. I know that this is the snippet to get country code

<xsl:value-of select="shipping/country_id"/>

My requirement is to fetch country name which in Magento is

Mage::getModel('directory/country')->load($country_code)->getName();

But in xsl how to call above getName() method

Hey genius guys plz help me find right way:

<xsl:value-of select="php:functionString('Mage_Directory_Model_Country::load', shipping/country_id)"/>

Something like this..... ?

In recent versions of the extension (that is any version since December 2012) you would retrieve it like this:

<xsl:value-of select="shipping/country_name"/>

For older versions, this field was not available without customizations and you should upgrade the extension. Go to www.xtento.com and click on XTENTO > My Downloads.
