Autoindent not working

[fornaeffe]

Problem: auto indentation doesn't work.

With a file like this, named "prova.xml":

<?xml version="1.0" encoding="UTF-8" ?>
<root>
    <tag></tag>
</root>

Moving the cursor between <tag> and </tag> and typing return it does not increment indentation nor add a new line for content, it just keeps previous indentation:

<?xml version="1.0" encoding="UTF-8" ?>
<root>
    <tag>
    </tag>
</root>

even if I have "editor.autoIndent": "full" in settings.

Version:

VS Code:

Version: 1.96.4 (user setup)

XML:

Identifier
redhat.vscode-xml
Version
0.27.2

What I tried:

• Checked with pre-release version of XML (same behavior)
• Checked that auto indentation works with html (it works)
• Checked that "XML" shows on bottom right on the status bar of VSCode (it shows).
• Cheched that "editor.autoIndent": "full" is not overridden for xml, or by workspace settings
• Added

"[xml]": {
    "editor.autoIndent": "full",
    "editor.defaultFormatter": "redhat.vscode-xml",
    "editor.formatOnType": true,
    "editor.tabSize": 4,
    "editor.insertSpaces": true
}

to VSCode settings (also tried to add some of these separately)

• Checked the output for XML Support:

[Info  - 10:44:00 AM] gen 28, 2025 10:44:00 org.eclipse.lemminx.XMLLanguageServer initialize()
Message: Initializing XML Language server
LemMinX Server info:

 - Java : C:\Program Files\Java\jre1.8.0_431
 - VM Version : 1.8.0_431
 - Git acacf75 - [maven-release-plugin] prepare release 0.29.0

• Disabled other extensions

• Reinstalled VSCode

• Toggled developer tools, and the Console displays this error:

console.ts:137 [Extension Host] [relatedFiles] unknown language xml
EYi	@	console.ts:137

• Forced language association both manually (Change language mode in Command Palette) and with

"files.associations": {
    "*.xml": "xml"
}

even if it always showed "XML" on the status bar, even without manual association.

It's just sad that this is just sitting here without any response. I am facing this same exact problem. Did you end up solving it?

[fornaeffe]

Unfortunately no. I still have to manually indent.

@mhrafin I understand your comment. We try to do our best to maintain vscode-xml but we are very busy with other projects.

@datho7561 have you tried this issue?

[datho7561]

I'll take a look

I'll take a look

Thanks @datho7561 !

@angelozerr the released version has the bug. The prerelease doesn't. For some reason, #1063 fixed it. I think that this bug is annoying enough that we should do a bugfix release of the extension.

@fornaeffe @mhrafin if you have a chance, could you see if switching to the the prerelease version of the extension fixes the issue for you?

If you have time to do that it would be very nice!

I'll look into doing that first thing tomorrow.

I can confirm that switching to the prerelease version solves the issue.

[angelozerr]

Thanks @mhrafin for your feedback.

@datho7561 please create a new release of vscode-xml if you have time.Thanks so much.
