I want to add xml:space="preserve" to every element in Xliff files like this one:
<?xml version="1.0" encoding="utf-8"?>
<xliff version="1.2" xmlns="urn:oasis:names:tc:xliff:document:1.2">
<file datatype="plaintext" source-language="en-US" target-language="de-DE" date="2023-01-19T14:30:55Z" xml:space="preserve">
<body>
<trans-unit size-unit="char" approved="no" maxwidth="70" id="TITLE">
<source>Add test scripts to execution queue</source>
<target state="translated">Testskripte zur Ausführungs-Queue hinzufügen</target>
</trans-unit>
<trans-unit size-unit="char" approved="no">
<source>Dynamic ID</source>
<target state="translated">Dynamic-ID</target>
</trans-unit>
<trans-unit size-unit="char" approved="no" maxwidth="132">
<source>Identification</source>
<target state="translated">Identifikation</target>
</trans-unit>
</body>
</file>
</xliff>
The Python script I have looks like this, but also adds ns0: to the beginning of each element in the XML file.
import xml.etree.ElementTree as ET
tree = ET.parse("input.xlf")
root = tree.getroot()
for trans_unit in root.iter("{urn:oasis:names:tc:xliff:document:1.2}trans-unit"):
trans_unit.attrib["{http://www.w3.org/XML/1998/namespace}space"] = "preserve"
tree.write("output.xlf")
Why does that happen and can someone help to improve the script?
OK, adding
ET.register_namespace("", "urn:oasis:names:tc:xliff:document:1.2")and then alsoencoding='utf-8', xml_declaration=True)to thetree.writestatement did the trick. Thanks, @mzjn!
