very lightweight filter for html
|

(without using any dynamic memory - some memory is allocated only at the beginning - in ctors)
|

this filter has O(n) complexity over the whole html string
|

|
||||
such tags as: <script> <pre> <textarea> are treated in a special way
|
||||
all characters between the opening and closing tag (<script>....</script>) are untouched
|
||||
|
||||
if the filter finds that there are not closed tags it will close them,
|
||||
if the filter finds a closing tag which doesn't have an opening tag - it will skip it
|
||||
|
||||
tags which don't need to be closed: meta, input, br, img, link
|
||||
look at CheckExceptions() method
|
||||
|
||||
the filter recognizes xml simple tags (with / at the end) such as: <br />
