- \class QxtHtmlTemplate QxtHtmlTemplate
- \ingroup QxtWeb
- \brief Basic Html Template Engine
-
- open a file containing html code and php style variables.
- use the square bracket operators to assign content for a variable
-
- \code
- QxtHtmlTemplate index;
- if(!index.open)
- return 404;
- index["content"]="hello world";
- echo()<<index.render();
- \endcode
- the realatet html code would look like:
- \code
- <html>
- <head>
- <title>Test Page</title>
- </head>
- <?=content?>
- </html>
- \endcode
-
- funny storry: whe are using this class to make our documentation (eat your own dogfood, you know ;).
- but when we where parsing exactly this file you read right now the first time, QxtHtmlTemplate got stuck in an infinite loop. guess why. becouse of that example above :D
- So be warned: when you assign content to a variable that contains the variable name itself, render() will never return.

- \fn QxtHtmlTemplate::open(const QString& filename)
- Returns true on sucess and false on failure.
- note that it will also return false for an empty html file.
-
- \fn QString QxtHtmlTemplate::render() const
- Uses the variables you set and renders the opened file.
- returns an empty string on failure.
- Does NOT take care of not assigned variables, they will remain in the returned string
