HTML Editor: Compose and output HTML documents

[DESCRIPTION]

    The HTML_Editor is meant to dynamically compose and output HTML documents.
    
    It provides functions to add many different types of the HTML elements to the document that 
    is being composed.
    
    Using HTML_Editor with classes like the PEAR::HTML_Table and PEAR::HTML_Forms or other 
    PEAR::HTML_* classes it provides a complete interface to create HTML documents of any 
    complication or parts of HTML formatted text on the fly. 
    
    With this class you can create any tags enclosed text like(P, H(1-6), B, LI, UL, SPAN, etc) 
    with any of attributes. You can also create link, image, meta tags.
    
    If you use PHP 5 you can reformat the output with the tidy extension. There is tidy.cnf 
    file included with all options available and you can customize it as you like to change output.
    
    this class also include very simple CSS creation class. It is called CSS_Editor. It has 
    3 main methods. setElement, setProperties, getCss.
    
    example of use
    
    1  $css = new CSS_Editor;
    2
    3  $h1 = $css->setElement('H1');
    4
    5  $array = (
    6      'color' => '#663399',
    7      'font-weight' => 'bold'
    8  );
    9  $css->setProperties($h1, $array); 
    10 
    11 $a = $css->setElement();
    12 $css->setProperties($a, array('text-decoration' => 'none'));
    13 
    14 $text_css = $css->getCss();
    
    in this example first we create new class in line 1, then in line 3 create an element H1 for 
    formating <H1> tag. than in lines 5-8 we create array of formatting properties and set these 
    properties to H1 element in line 9. Another element with pseudo class is created in line 11. 
    it could be not only 'a:hover' but link to id '#my_link' or class '.my_link'. In line 12 we 
    set property for  'a:hover' element. And finally in line 14 we get all this as a formated 
    string that would looks like this:
    
    H1{
       color:#663399;
       font-weight:bold;
    }
    
    a:hover{
        text-decoration:none;
    }


[INSTALLATION]

[Tidy]
    For php5 there is feature build-in for formating output with tidy. This uses tidy.cfg. This 
    file content all setting available for tidy. You just customize it the way you need. The 
    tidy.cfg file must be in the same directory as html_editor.php.
