QWeb is the primary templating engine used by Odoo. It is an XML templating engine and used mostly to generate XML, HTML fragments and pages. To create new XML template, please see :doc:`QWeb Templates documentation <https://www.odoo.com/documentation/15.0/developer/reference/frontend/qweb.html>` In **input** you have an XML template giving the corresponding input etree. Each etree input nodes are used to generate a python function. This fonction is called and will give the XML **output**. The ``_compile`` method is responsible to generate the function from the etree, that function is a python generator that yield one output line at a time. This generator is consumed by ``_render``. The generated function is orm cached. In the graphic below you can see theresume of the call of the methods performed in the IrQweb class.
