[TYPO3-core] RFC #14748: Span tags with multiple classes being removed by RTE transformation

[Stanislas Rolland]

Hi,

This is a SVN patch request.

Type:
Bugfix

Problem:
htmlparser option 'fixAttrib' allows to specify a list of admissible 
values for an attribute. The feature is used by the RTE transformation 
to remove any unallowed class from span and paragraph elements. However, 
if the element has multiple classes, the value will not be found in the 
list.

Solution:
In the case of the class attribute, the htmlparser should check if each 
class specified on the attribute is in the list of admissible values, 
and remove any non admissible value.

Regards,
Stanislas
