Cross-platform Tools for Translators

XLIFFChecker

XLIFFChecker logo

Verify the validity of your XLIFF (XML Localisation Interchange File Format) documents in any platform with XLIFFChecker.

XLIFFChecker checks your documents against the XLIFF DTD (version 1.0) or XLIFF Schemas (versions 1.1 and 1.2). It also verifies if they follow the requirements described in XLIFF specifications. XLIFF is a complex format and verifying against an XML grammar is not enough to ensure compliance with the standard.

XLIFF is becoming increasingly popular as exchange format between users of CAT (Computer Aided Translation) tools. Compliance with the official specifications published by OASIS is essential for allowing interoperability between tools.

The source code of XLIFFChecker is available under Eclipse Public License v1.0. XLIFFChecker users can freely inspect the code to understand why the program complains at an error in an XLIFF file or to confirm a bug/omission in the validator program.

Executable versions (binaries) of XLIFFChecker are included in Swordfish III installers.

The source code of XLIFFChecker is available in the following SVN repository at SourceForge:

Errors found in the source code should be reported to tech@maxprograms.com.

XLIFFChecker supports XLIFF versions 1.0, 1.1 and 1.2 in its two flavours (Strict and Transitional).
