XLIFF 1.1 e 1.2¶

Nota

XLIFF 2.0 is a different format and is not backwards compatible with XLIFF 1.2.

XML-based format created to standardize translation files, but in the end it is one of many standards, in this area.

XML Localization Interchange File Format (XLIFF) is usually used as bilingual, but Weblate supports it as monolingual as well.

Weblate supporta XLIFF in diverse varianti:

XLIFF 1.2 translation file: Standard XLIFF file. Placeables handling is controlled by the xliff_placeables Parametri del formato file.
XLIFF 1.2 with gettext extensions: XLIFF enriched by XLIFF 1.2 Representation Guide for Gettext PO to support plurals.
XLIFF 1.2 with Apple extensions: XLIFF enriched by Apple to support plurals.

Translation states¶

The state attribute in the file is partially processed and mapped to the «Needs edit» state in Weblate (the following states are used to flag the string as needing edit if there is a target present: new, needs-translation, needs-adaptation, needs-l10n). Should the state attribute be missing, a string is considered translated as soon as a <target> element exists.

If the translation string has approved="yes", it will also be imported into Weblate as «Approved», anything else will be imported as «Waiting for review» (which matches the XLIFF specification).

While saving, Weblate doesn’t add those attributes unless necessary:

The state attribute is only added in case string is marked as needing edit.
The approved attribute is only added in case string has been reviewed.
In other cases the attributes are not added, but they are updated in case they are present.

That means that when using the XLIFF format, it is strongly recommended to turn on the Weblate review process, in order to see and change the approved state of strings.

Similarly upon importing such files (in the upload form), you should choose Import as translated under Processing of strings needing edit.

Whitespace and newlines in XLIFF¶

Weblate controls how whitespaces are handled with the xml_whitespace_handling Parametri del formato file for XLIFF components:

Follow xml:space — honor xml:space attributes in the file (and the XLIFF default when the attribute is missing).
Always preserve — keep all whitespace and set xml:space="preserve" on units (Weblate’s default for new units).
Always normalize — collapse whitespace even when the file sets xml:space="preserve".

To keep newlines or surrounding spaces when following xml:space, mark the string with xml:space="preserve":

    <trans-unit id="10" approved="yes">
        <source xml:space="preserve">hello</source>
        <target xml:space="preserve">Hello, world!
</target>
    </trans-unit>

Placeables in XLIFF¶

Weblate controls how XML elements inside XLIFF content are handled with the xliff_placeables Parametri del formato file:

Plain text — escape XML elements in the content.
Placeables — preserve placeables and other XML elements (the default). Tags then appear as placeholders in the editor.

Specifying translation flags¶

You can specify additional translation flags (see Customizing behavior using flags) by using the weblate-flags attribute. Weblate also understands maxwidth and font attributes from the XLIFF specification:

<trans-unit id="10" maxwidth="100" size-unit="pixel" font="ubuntu;22;bold">
   <source>Hello %s</source>
</trans-unit>
<trans-unit id="20" maxwidth="100" size-unit="char" weblate-flags="c-format">
   <source>Hello %s</source>
</trans-unit>

The font attribute is parsed for font family, size and weight, the above example shows all of that, though only font family is required. Any whitespace in the font family is converted to underscore, so Source Sans Pro becomes Source_Sans_Pro, please keep that in mind when naming the font group (see Managing fonts).

Chiavi stringa¶

Weblate identifies the units in the XLIFF file by resname attribute in case it is present and falls back to id (together with file tag if present).

The resname attribute is supposed to be human friendly identifier of the unit making it more suitable for Weblate to display instead of id. The resname has to be unique in the whole XLIFF file. This is required by Weblate and is not covered by the XLIFF standard - it does not put any uniqueness restrictions on this attribute.

File di esempio¶

File esempio XLIFF:

<?xml version='1.0' encoding='UTF-8'?>
<xliff xmlns="urn:oasis:names:tc:xliff:document:1.1">
    <file>
        <body>
            <trans-unit weblate-flags="c-format, max-length:100">
                <source xml:space="preserve">Hello, world!
</source>
            </trans-unit>
            <trans-unit>
                <source xml:space="preserve">Orangutan has %d banana.
</source>
            </trans-unit>
            <trans-unit>
                <source xml:space="preserve">Try Weblate at &lt;https://demo.weblate.org/&gt;!
</source>
            </trans-unit>
            <trans-unit>
                <source>Thank you for using Weblate.</source>
            </trans-unit>
        </body>
    </file>
