[x3d-public] JSON validation

[Don Brutzman]

Andreas, thanks for the example jsonlint test link.

Am happy to report that jsonlint check links have been added for all of the 3884 .json links in the X3D Examples Archives.

	http://www.web3d.org/x3d/content/examples/X3dResources.html#Examples

Sample:

	http://www.web3d.org/x3d/content/examples/Basic/CAD/CatiaHubAssemblyCombined.json

	http://jsonlint.com/?json=http://www.web3d.org/x3d/content/examples/Basic/CAD/CatiaHubAssemblyCombined.json

So far it looks excellent.  This will facilitate further refinement.

Found one problem scene (taken from specification) which includes intentionally challenging quotations:

	http://jsonlint.com/?json=http://www.web3d.org/x3d/content/examples/Basic/X3dSpecifications/X3dHeaderPrototypeSyntaxExamples.json

=============================================
Error: Parse error on line 231:
... "#comment": "alternative: Text s
-----------------------^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'
=============================================

Line 231 is the comment in the following block:

"Shape": {
	"-geometry": {
		"Text": {
			"@string": ["He said, \"Immel did it!\""]
		}
	},
	"-children": [{
		"#comment": "alternative: Text string='\"He said, \"Immel did it!\"\"'"
	}],
	"-appearance": {
		"Appearance": {
			"-material": {
				"Material": {}
			}
		}
	}
}

Original .x3d form:

<Shape containerField='proxy'>
	<Text string='"He said, \"Immel did it!\""'/>
	<!-- alternative: Text string='"He said, \"Immel did it!\""' -->
	<Appearance>
		<Material/>
	</Appearance>
</Shape>

So the Text MFString is handled OK but the comment is not.  Shouldn't be hard to fix, will look at that.

Other than that, haven't found problems.  No doubt you have found a few others John!  Still, quality assurance continues to improve.

Have fun with X3D JSON!
