[x3d-public] X3DJSAIL CommandLine enhancement; Issue with JinLOA4.x3d

[John Carlson]

See requested X3DJSAIL CommandLine possible enhancement—read in X3D XML as
DOM into X3D scenegraph and write out X3D scenegraph (X3D typed object) as
XML for round-tripping.  I want to do this without writing Java source code.

I have been looking for a way to read in an XML file and output XML, but
this doesn’t seem to be possible with the X3DJSAIL CommandLine program.  I
don’t know the right combination of parameters.  I can provide Java code
which does this and shows the problem, but ideally, I could do this with
CommandLine.

Apologies for any possible obtuseness of the below report.

There appears to an issue with X3DJSAIL X3DLoaderDOM.java or
X3D.toFileX3D().  Base Java XML parser and transformer appears to be OK.  I
have not been able to debug this, unfortunately, beyond some initial
stuff.  The problem appears to be with long attribute values—they get
removed along with the attribute itself.

I don’t really have a clue what’s going on, and the issue is only with one
IndexedFaceSet/Coordinate/TextureCoordinateset, within the skull* named
HAnim parents.  They happens to have the longest attribute values in the
file.  I have not tried moving the attributes in the file yet, or
duplicating the HAnimJoint elsewhere in the file.

There’s also warnings with the original file that need to be fixed.  See
enclosure for link to archive.

If desired, I can convert XML file to python or java for additional testing
to determine whether the problem it with the loader or XML output.  I don’t
know if the Java will compile.

Thanks!

John
