[Bug 53965] New: Writing a new line after writing a full end element(WriteFullEndElement)
by WineHQ Bugzilla Aug. 27, 2026

https://bugs.winehq.org/show_bug.cgi?id=53965 Bug ID: 53965 Summary: Writing a new line after writing a full end element(WriteFullEndElement) Product: Wine Version: 7.21 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: xmllite Assignee: wine-bugs(a)winehq.org Reporter: k.kahurani(a)gmail.com Distribution: --- Created attachment 73553 --> https://bugs.winehq.org/attachment.cgi?id=73553 Test case It doesn't look possible to write a whitespace character after writing a full end element with WriteFullEndElement. It looks to me like this should be possible just like it is possible with WriteEndElement. I have also noticed that native xmllite sometimes breaks(not sure whether this is a feature or a bug) but at times native xmllite doesn't write new lines after writing the elements. I'm not sure how exactly this happens but the possible work-around in this is to manually write new lines(with WriteWhitespace) which means this issue could easily break working code. I'm not sure how to fix this right away so I am submitting a bug. As can be seen in the attached diff, wine doesn't pass the test but native does. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
