Raúl,
Thank you for sending that schema and your test code. That helped
me understand what's happening.
One thing we need to understand is that the elements inside of a
`calibration_parameters`/`calibration_parametersSub` (specifically
`cm_mm01`, `co_mm01`, `cm_mm02`, etc) are each a `xsd:complexType`.
They contain floats, but they are not floats themselves. They need
to be instances of Python classes. And actually, since they are
each defined with `maxOccurs` greater than 1, they each contain an
array of floats. So, you can either (1) create them with a Python
list or (2) create them and then use the `add_xxx` methods to add
individual floats.
And then, your schema requires more nesting than what we originally
created. We need the following nesting:
<commands>
<tc>
<change_adcs_calibration_parameters due_time="10">
<calibration_parameters>
<mm_working>
<mgm1>1.</mgm1>
...
</mm_working>
<cm_mm01>
...
</cm_mm01>
<co_mm01>
<offset>1.2</offset>
...
Oh, and, in order to get it to validate, each calibration matrix
needs exactly 9 values and each offset matrix needs to contain
exactly 3 offsets. That's because, for example, of the following:
minOccurs="9" maxOccurs="9"
in the definition of `calibration_matrix`.
Whew! It's a little tricky. But, if we did not want it to be
tricky and complicated, I suppose we probably wouldn't be using XML.
Sigh. Actually, I suspect that what you *do* with this data is even
a lot more complex, yet.
I've attached a python script that is a modification of the script
that you sent me. It reflects the changes suggested above.
I used the following to generate output:
$ ./test04.py output.xml
If you have `xmllint` installed on your machine, you can use the
following to validate your output:
$ xmllint --noout --schema tc-schema.xsd output.xml
I hope this helps. And, hope your project goes well.
Let me know if and when you have more questions.
Dave
