[solved] DocumentList and XML hierarchy?

Edit: I think I found out roughly how to do it. The syntax is kind of picky. If you do things in the wrong order, the XML can turn out a little bit different.

"Example
renoise.Document.create("Song") {
    file_path = "full path",
    bpm = 126
}

songs = renoise.Document.DocumentList()

hist = renoise.Document.create("SongHistory") {
  Songs = songs
}

-- create song instances

song2 = renoise.Document.instantiate("Song")
song3 = renoise.Document.instantiate("Song")

song2:property("file_path").value = "testpath"
song3:property("file_path").value = "another path"

-- add to document list
songs:insert(song2)
songs:insert(song3)


-- test save and load
hist:save_as("history_new.xml")

hist:load_from("history_new.xml")

print(hist:property("Songs")[2]:property("file_path").value)

OP:

Regarding renoise.Document:

Is it possible to use the save_as/load_from methods to load XML files with more than one depth? (example below). Since renoise.DocumentList don’t have those methods, maybe not?

I’ve also tried to construct the document by using a template table without success. And I’ve tried to load a manually made XML to no avail. I’m guessing that the only extra depth possible for lists is the one provided by ObservableBool/Number/StringList ?

I could workaround by starting to name the elements “Element1”, “Element2” et c, but wanted to check here first if it’s possible to achieve what I want.

XML example
<?xml version="1.0" encoding="UTF-8"?>
<SongHistory doc_version="0">
  <Songs>
    <Song>
      <bpm>0.0</bpm>
      <instr_no>0.0</instr_no>
      <last_updated> </last_updated>
      <file_path> </file_path>
      <rating>0.0</rating>
      <comment> </comment>
      <seq_no>0.0</seq_no>
    </Song>
    <Song>
      <bpm>0.0</bpm>
      <instr_no>0.0</instr_no>
      <last_updated> </last_updated>
      <file_path> </file_path>
      <rating>0.0</rating>
      <comment> </comment>
      <seq_no>0.0</seq_no>
    </Song>
  </Songs>
</SongHistory>
