QTI Rendering

The QTI Software Development Kit enables you to transform XML serialized QTI files into their (X)HTML5 Goldilocks equivalent. The following shell command renders the path/to/qti.xml QTI file into an HTML5 document using the (X)HTML5 Golidlocks rendering flavour with indentation formatting. The rendering output (stdout) is redirected to the /home/jerome/qti.html file.

./vendor/bin/qtisdk render -df --source path/to/qti.xml --flavour goldilocks > /home/jerome/qti.html

For additionnal help and information, just call the help screen to know about the features provided by the rendering binaries!

./vendor/bin/qtisdk render --help

Configuration

As for other major PHP frameworks such as Doctrine, Zend Framework 2 or PHPUnit, QTI-SDK makes use of annotations. In such a context, the two following Zend Opcache configuration directives must be configured as below:
