Fix exporter tests

[tobiasdiez]

As was recognized in #3959, some of the exporter tests are not working correctly.

MsOffice is resolved.
ModsExporter needs to be checked again

[tobiasdiez]

The tests are now fixed thanks to @NivedhaSunderraj.

[NivedhaSunderraj]

@tobiasdiez I have fixed only testExportAsModsAndThenImportAsMods.... I couldn't fix the other two tests :(

[Siedlerchr]

@NivedhaSunderraj Which ones are still failing?

[NivedhaSunderraj]

@tobiasdiez testPerformExport and testImportAsModsAndExportAsMods are still not fixed and they both have same issue I think

[Siedlerchr]

@NivedhaSunderraj Could you investigate what exactly is failing? Maybe the format of the xml files has changed? That was the case for the MsOffice stuff

[NivedhaSunderraj]

@tobiasdiez Sure I'll look into it 👍

[NivedhaSunderraj]

@tobiasdiez Looks like the temp file created has an attribute 'xsi:type="mods:stringPlusLanguagePlusSupplied"' , but this is not in the xml files. And this caused the error... Do I add the attribute to xml file? Or modify export ?

[tobiasdiez]

I'm not too familiar with the Office export, but this attribute does not seem to be utterly important and I'd hence say remove it from the reference files.

[NivedhaSunderraj]

@tobiasdiez the xml reference files don't have the attribute ... It is being added when exporting it using modExport. So should I add the attribute in the reference xml file?

[tobiasdiez]

Ah ok, I misunderstood you there. Yes, then please add it!

[NivedhaSunderraj]

@tobiasdiez Sure 👍
