XMLParser
=========
**Inherits:** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`
Low-level class for creating parsers for `XML <https://en.wikipedia.org/wiki/XML>`__ files.
.. rst-class:: classref-introduction-group
Description
-----------
This class can serve as base to make custom XML parsers. Since XML is a very flexible standard, this interface is low-level so it can be applied to any possible schema.

----
.. _class_XMLParser_method_get_named_attribute_value:
.. rst-class:: classref-method
:ref:`String<class_String>` **get_named_attribute_value** **(** :ref:`String<class_String>` name **)** |const|
Gets the value of a certain attribute of the current element by name. This will raise an error if the element has no such attribute.
