A Swift framework for parsing and modifying XLIFF files.
An example XLIFF file:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xliff version="1.2">
<file original="Sample/en.lproj/Localizable.strings" source-language="en" target-language="it">
<body>
<trans-unit id="common.greeting.hello" xml:space="preserve">
<source>Hello</source>
<target>Ciao</target>
<note>Casual greeting</note>
</trans-unit>
<trans-unit id="How are you?" xml:space="preserve">
<source>How are you?</source>
<target>Come stai?</target>
<note></note>
</trans-unit>
</body>
</file>
<file original="AnotherSample/en.lproj/Localizable.string" source-language="en" target-language="it">
<body>
<trans-unit id="Thank you" xml:space="preserve">
<source>Thank you</source>
<target>Grazie</target>
</trans-unit>
<trans-unit id="You’re welcome" xml:space="preserve">
<source>You’re welcome</source>
<target state="needs-review-translation">Prego</target>
<note>Casual thanks</note>
</trans-unit>
<trans-unit id="How old are you?" xml:space="preserve">
<source>How old are you?</source>
</trans-unit>
</body>
</file>
</xliff>Import the framework:
import XLIFFKitOpening an XLIFF:
let document = try XLIFFDocument(data: data)Iterating through the XLIFF's translation units:
for file in document.files {
for translationUnit in file.body.translationUnits {
print(translationUnit.source, translationUnit.target)
}
}Where a XLIFFTranslationUnit is:
public struct XLIFFTranslationUnit: Hashable {
public let uuid: UUID
public let id: String
public let source: String
public let note: String?
public var target: String?
public var state: XLIFFState?
}Modifying a translation unit:
let file = document.files[0]
var translationUnit = file.body.translationUnits[0]
translationUnit.target = "New value"
translationUnit.state = .needsReviewTranslation
document.updateTranslationUnit(forFileUUID: file.uuid, to: translationUnit)The UUID is not present in the XLIFF; one is generated for files and translation units. It is used to refer to and track elements in the document.
After making a modification, document.hasUnsavedChanges will become true. Call document.commitUnsavedChanged() to write the changes back to the underlying XML document.
Saving changes:
if document.hasUnsavedChanges {
document.commitUnsavedChanges()
}
let newData = document.xmlData()
