Bug Report: Duplicate <measure number="1"> Causes Unexpected Behavior in Verovio

[Dahurica]

Hello,

While using Verovio to render music scores, I encountered an issue when the XML contains two elements. In such cases, all data within the second is inherited by the first . This behavior leads to some unexpected bugs in the rendered score.

Could you please look into this issue? Let me know if you need additional details or examples to reproduce the problem.

Thank you for your assistance!

This issue does not fulfil the report requirements. It does not describe the issue accurately and provides no minimal data and expected output. Please do not open again an issue with so little information and fill the template as expected

Hello, I was a bit busy last week and got delayed. Here is the problem XML. The original XML contained two songs in one file. I consulted the team member responsible for the piano content on our side, and they said it was reasonable.
So, I simply reproduced a problematic XML for this issue.

The MusicxML→Humdrum→MEI converter converts the MusicXML data closer to the intended original notation (which you should have included with the initial issue submission):

The problem is that the MusicXML→MEI converter is assuming unique measures numbers. Unless you (verovio programmers) can provide documentation for MusicXML that says that measure numbers must be unique, the insertion of the <dir> should not make this assumption (in theory the measure numbers should be unique, at least in early MusicXML, but that requirement for converting between score-wise and part-wise seems to have softened over time).

https://www.w3.org/2021/06/musicxml40/musicxml-reference/elements/measure-partwise

This page says "should" and not "must" for unique measure@number values:

The problem is that there are three <measure number="1"> in a row, and the MusicXML→MEI converter is having problems with that. It would be better if the text directions are inserted within the measure that they are found in rather than relying on measure@number.

First measure of example (prestissimo):

Note that the MusicXML element <opus> is required for correct encoding of multiple movements:

https://www.w3.org/2021/06/musicxml40/opus-reference/elements/opus

Likely the MuseScore developers do not know this, unless this is a hack to represent multiple movements in MuseScore/MusicXml by resetting the measure numbers. In any case the conversion of this MusicXML file will not/should not expand into three movements in the MEI conversion since <opus> is not being used. But the MEI conversion should not assume unique measure numbers, and instead place the converted <dir> within the measure that the original <direction> was found.

Opening the MusicXML file back into MuseScore:

Exporting as MEI and then rendering with verovio, the preservation of the text is better, but the first <dir> in each measure is missing:

Click for MEI directly exported from MuseScore.

Note there are three <measure n="1"> measures as with the MusicXML export from MuseScore.

Here is how the measures are renumbered in MuseScore:

First select a measure and right click, then choose "Measure properties..."

Then "Add to measure number" a value that will set the current measure to 1 (I was testing with the first "movement" being 9 measure long in this case):

Result is converting measure 9 into measure 1:
