I want to change layout of category listing page from 2columns-left to 1column by xml.
for this what i have tried so far.
In root\magento-ce-2.0.0\vendor\magento\module-catalog\view\frontend\layout\catalog_category_view.xml
I changed
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="2columns-left" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
to
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
but this is not working, whereas if i change Page Layout of category from admin of then changes reflecting but i don't want to make changes from admin i want it from xml.
Can any one please help me for this.
