TYPO3 Core

* Gets labels to be used in JavaScript fetched from a locallang file.

*

* @param string Input is a file-reference (see t3lib_div::getFileAbsFileName). That file is expected to be a 'locallang.xml' file conataining a valid XML TYPO3 language structure.

* @param string Language key

* @param string Character set (option); if not set, determined by the language key

* @param integer Error mode (when file could not be found): 0 - syslog entry, 1 - do nothing, 2 - throw an exception

* @param string $selectionPrefix: Prefix to select the correct labels (default: '')

* @param string $stripFromSelectionName: Sub-prefix to be removed from label names in the result (default: '')

* @return void
