Exporting to .XML works for single instrument, but not for 2 or more

[Viktor Mastoridis]

On Frescobaldi 3.2 and Lilypond 2.24 I am able to export single instruments as XML files with great success.

However, if I try to export two or more of them at the same time, I get the error below.

I have 4 staffs, they are all in the same document, I only hide the instruments by using % in the \score section.

I was wondering whether you can see an obvious error in the output below.

The document is linked to several other external docs, but if needed, I will try to compile a simple version.

Here's the error output in Frescobaldi:

Thank you, Federico.

Yes, it's the same bug reported there.

I'll watch the spaces.
