Load and retrieved parsed XML

[samuelbradshaw]

It would be helpful if I could modify the MEI content and pass it back into Verovio without serializing and deserializing it.

Currently, I need to do something like this:

data.meiString = vrvToolkit.getMEI();
data.meiParsed = (new DOMParser()).parseFromString(data.meiString, 'text/xml');
if (!options.showChords) {
  let harms = data.meiParsed.querySelectorAll('harm');
  for (const harm of harms) {
    harm.remove();
  }
}
data.meiString = (new XMLSerializer()).serializeToString(data.meiParsed);
vrvToolkit.loadData(data.meiString);

I'd like to do something like this:

data.meiParsed = vrvToolkit.getMEI({ serialized: false, });
if (!options.showChords) {
  let harms = data.meiParsed.querySelectorAll('harm');
  for (const harm of harms) {
    harm.remove();
  }
}
vrvToolkit.loadData(data.meiParsed);

I see that Toolkit::GetMEI has a serialized option, but it doesn't seem to be exposed to the JavaScript toolkit (or I can't figure out how to set it).

Sometimes I need to modify source MusicXML, too, so it would be helpful if I could pass parsed MEI or MusicXML into vrvToolkit.loadData().

I don't see how that can be possible since verovio is using pugixml in C++, while Javascript has a separate XML parser, DomParser, that does similar things but in a different language (so there is a problem of two different languages using two different parsers).

There is an edit function in the toolkit (which I have not used). @lpugin can discuss using that to manipulate the MEI data inside verovio.

I didn't think about the fact that parsed XML wouldn't be the same between languages. So much for that idea! :) Thanks.
