TTextHighlighter does syntax highlighting its body content, including
static text and rendering results of child controls.
You can set {@link setLanguage Language} to specify what kind of syntax
the body content is. Currently, TTextHighlighter supports the following
languages: ABAP, CPP, CSS, DIFF, DTD, HTML, JAVA, JAVASCRIPT, MYSQL, PERL,
PHP, PYTHON, RUBY, SQL, XML and PRADO, where PRADO refers to PRADO template
syntax. By setting {@link setShowLineNumbers ShowLineNumbers}
to true, the highlighted result may be shown with line numbers.
Note, TTextHighlighter requires {@link THead} to be placed on the page template
because it needs to insert some CSS styles.
/**

protected function highlightCode($matches)

$text = html_entity_decode($matches[2], ENT_QUOTES, 'UTF-8');
$this->setLanguage($matches[1]);
