Feature: #66269 - Fluid: Remove ViewHelper xmlns-attributes and specified html tag
==================================================================================
See :issue:`66269`
Description
===========
With the introduction of using xmlns:* attributes to include ViewHelpers, it is possible to have IDE support for Fluid
templates.
However, the problem is that the xmlns:* attributes and the corresponding tag will also be rendered, which is not
desired most of the time. A workaround to avoid this is to use sections.
However, this solution is counter-intuitive, is not available in layouts and causes extra processing overhead.
.. code-block:: html
Impact
======
The xmlns:* attributes for valid ViewHelper namespaces will now be removed before rendering.
Such ViewHelper namespaces follow this URI pattern:
.. code-block:: html
http://typo3.org/ns/
Examples:
.. code-block:: html
http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers
http://typo3.org/ns/GeorgRinger/News/ViewHelpers
xmlns attributes for non-ViewHelper namespaces will be preserved.
Furthermore an additional data-attribute to HTML-Tags is introduced.
.. code-block:: html
data-namespace-typo3-fluid="true"
If this attribute is specified on the HTML-Tag, the HTML-tag itself won't be rendered as well.
(Also a corresponding closing tag will not be rendered for that template.)
This is useful for various IDEs and HTML auto-completion.
Examples
========
Include ViewHelper namespaces on an existing tag (e.g. root xml tag) via xmlns attributes for Fluid and News extension.
.. code-block:: xml
{newsItem.title}
News-Detail
Output is then
.. code-block:: xml
...
Include ViewHelper namespaces with HTML-tag and a data-namespace-typo3-fluid="true" attribute via xmlns attributes for
Fluid and News extension.
.. code-block:: html
{newsItem.title}
News-Detail
The output contains everything excluding the HTML-tag.
.. index:: Fluid
