[x3d-public] compiling abox.future.py Re: Please instruct me what Ishouldbetocatch up withyouRe:X3D/XSeen Python API (PyX3D or X3DPy)

Dear Prof. Masaki Aono,

this is good news.  *short_empty_elements*=*False*  generates HTML
compatible tag syntax with full closing tags: instead of <Material />,
<Material></Material> is output. We need HTML rather than XML on the
jupyter page, since the page itself is a HTML document. There are other
options such as an IFrame or using a wrapper X3D with an Inline to the
actual content. which could accommodate XML but generating the full closing
tag is the simplest solution.

Looking up lxml, I found that

lxml.etree.tostring(root, method= 'html')

may also work to generate full closing tags using lxml but I did not have a
chance to test. Would you like to try that as well ?

Sincerely,

I think the next step is to copy/paste the HelloWorld.py into the Jupyter notebook and see if it builds and exports XML correctly, similar to Andreas Plesch’s binder, https://mybinder.org/v2/gh/andreasplesch/conda/master/?urlpath=lab/tree/sphere.ipynb but with the package import as you have, and package prefixes found in HelloWorld.py.   The only thing we’re testing in this step is the “x3dpsail” namespace inside jupyter.  Whereas Andreas’ solution had no package.  Ideally, I’d like to get Loren’s signoff on what we’re doing re: packaging and imports after the notebook is published again.
