Detailed Description

This class creates html output which is as minimal as possible and restricted to the rich text features supported in Qt. (http://doc.trolltech.com/4.4/richtext-html-subset.htm)

The output contains only the body content, not the head element or other metadata.

eg:

<p>
This is some <strong>formatted content</strong> in a paragraph.
</p>

instead of the content produced by qt:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0//EN" "http://www.w3.org/TR/REC-html40/strict.dtd">
<html><head><meta name="qrichtext" content="1" /><meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /><style type="text/css">
p, li { white-space: pre-wrap; }
</style></head><body style=" font-family:'Sans Serif'; font-size:10pt; font-weight:400; font-style:normal;">
<p style=" margin-top:12px; margin-bottom:12px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">This is some <span style=" font-weight:600;">formatted content</span> in a paragraph. </p></body></html>

Such tags should be created separately. For example:

AbstractMarkupBuilder *b = new TextHTMLBuilder();
MarkupDirector *md = new MarkupDirector(b);
md->constructContent();
QString cleanHtml("<head>\n<title>%1</title>\n</head>\n<body>%2</body>\n</html>")
.arg(document.metaInformation(QTextDocument::DocumentTitle))
.arg(b->getOutput());
QFile.write(cleanHtml);

Font formatting information on elements is represented by individual span elements. eg:

<span style"color:blue;"><span style="background-color:red;">Blue text on red background</span></span>

instead of

<span style="color:blue;background-color:red;">Blue text on red background</span>

It my be possible to change this if necessary.
