# Deprecation: #89037 - Deprecated LocallangXmlParser

See [forge#89037](https://forge.typo3.org/issues/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.
