**1) For ex: you have function getTitle() in Data.php at Namespace/Modulename/Helper** <?php namespace Namespace\Modulename\Helper; class Data extends \Magento\Framework\App\Helper\AbstractHelper { public function getTitle() { return "Testing"; } } **2) In layout.xml change xsi:type="string" to xsi:type="helper" and define helper class::methodName** <block class="Magento\Framework\View\Element\Html\Link\Current" ifconfig="custommodule/general/enable_footer_link" name="custommodule-link"> <arguments> <argument name="label" xsi:type="string">Custom Module</argument> <argument name="path" xsi:type="helper" helper="Namespace\Modulename\Helper\Data::getTitle"/> </arguments> </block>
