Deprecation: #89037 - Deprecated LocallangXmlParser 

See forge#89037

Description 

The \TYPO3\CMS\Core\Localization\Parser\LocallangXmlParser has been used to parse localization files based on the custom ll-XML format ("ll" refers to "locallang"). Since TYPO3 version 4.6 XLIFF is being used and therefore the previous support for locallang-XML files has been marked as deprecated.

Impact 

Calling \TYPO3\CMS\Core\Localization\Parser\LocallangXmlParser or using locallang-XML files will trigger a PHP E_USER_DEPRECATED error.

Affected Installations 

All installations using extensions using ll-XML localization files.

Migration 

Migrate all XML files to the XLIFF standard.
