This class is based in a superclass, the clsTag class. All the classes extends this one.
The Properties of this class are:
$indent : used to set the indentation of HTML code
$outputCode : holds the generated HTML code
$tag : holds the HTML tag being generated
$child : an array of objects that holds all the child nodes
of this tag.
$indenting : deprecated. it was intended to act as a flag of
indentation
The methods are:
InString(what,where): search through an array (where) looking for a
string (what)
GetAttributes(addAttr,attr): this method mixes the default tag's
attributes with the provided ones
clsTag(tag,attr,indenting): the class Constructor.
getOutputCode: returns as a string the generated HTML code
Generate: builds the code and output it.
AddNode(node): insert a node in the tag tree. For example, you can add
a row inside a table, or an image between opening and
closing A tags
HookIt: it was introduced as a sort of parent::constructor callback
function.
CloseTag: this is almost the only one method that is overcharged. It
adds the closing tag to the tree.
Classes that extends the clsTag class:
clsHTMLDocument: This should be the top class in the tree. It builds the HTML /HTML tags
clsHeaderSection: adds the HEAD /HEAD tags
clsTitle: adds the TITLE /TITLE tags
clsMeta: adds the META tag. This class overwrite the CloseTag method.

I think the most interesting part of this tutorial must be the support functions, the ones used to actually put this class to work. Those functions and their parameters are:
In every case the child parameter can be an object or an array of objects
in every case, the attr parameter (if present and/or not empty) represents the tag's attributes, like the border of a table, or the src of an img. the format of this parameter is: attr1=val;attr2=val;attr3=val;....;attrn=val
fnHTML(object [child])
fnHeader(object [child])
fnTitle(string [title])
fnMeta(string [attr])
fnStyleSheet(string stylesheet, string [attr]): The stylesheet parameter is the location of the .css file. it will generate a <link rel=stylesheet type=text/css href=«the style sheet»>
fnBody(string [attr], object [child])
fnTable(string [attr], object [child])
fnRow(string [attr], object [child])
fnCell(string [text], string [font], string [attr], object [child]): The text parameter is used in conjunction with the font parameter, and is used when you want to show text inside a cell, instead another tag.
fnFont(string [text], string [attr], object [child]): Just like the fnCell, but the font there is attr here.
fnParagraph(string [text], string [font], string [attr], object [child]): See fnCell
fnShowText(string text, string [attr]): insert text without formatting
fnImg(string src, string [id], string [attr])
fnLink(string [href], string [text], string [font], string [attr], object [child])
fnForm(string [action], string [name], string [hiddens], string [attr], object [child]): the hiddens parameter has the same format that the attr parameter, and it will generate the <input type=hidden> tags according to the name=value pairs.
fnOption: This function is used internaly, and should NEVER be used by you
fnSelect(string name, string [values], string [selvalue], string [attr]): the values parameter is an array. Its format is values["the_val"]="the text". the selvalue is a string, matching one key in the values array.
fnInput(string name,string [value], string [size], string [maxlength], string [attr]): It generates a <input type=text>
fnPassword(string name,string [value], string [size], string [maxlength], string [attr])
fnFile(string name, string [attr]): Builds a <input type=file>
fnTextArea(string name,string [value], string [rows], string [cols], string [attr]): It generates a <textarea>value</textarea>
fnHidden(string name, string [value], string [attr])
----------------------------
I will add more documentation in a few days... but I think the other support functions are quite self-explainatory. Below, a few examples...
----------------------------
$document=fnHtml(array(
fnHeader(array(
fnTitle("This is a test"),
fnStyleSheet("styles/mystyle.css")
)),
fnBody(
fnTable("",array(
fnRow("",
fnCell("This is a text","","align=center;bgcolor=#c0c0c0")
)
))
)
));
$document->Generate();
The example above will generate this code:
<html>
<head>
<title>This is a test</title>
<link rel=stylesheet type=text/css href="styles/mystyle.css">
</head>
<body>
<table border=0 cellpadding=0 cellspacing=0>
<tr>
<td align=center bgcolor="#c0c0c0">This is a test</td>
</tr>
</table>
</body>
</html>
