<div dir="ltr"><p dir="ltr">Hi John,</p>
<p dir="ltr">X3dom is designed to work with the XML encoding or a dom. So for x3dom it would be necessary to first create a DOM from the json. It will be difficult to get around that.<br></p>
<p dir="ltr">Cobweb has parsers which parse XML or vrml into a scene graph. So it should be possible to make a parser for json, probably following what the XML parser does. But the easier path would be also to create a DOM from the json first.</p><p>How do you envision you or others would use json encoded x3d content to add value to a project ? Easier manipulation as a js object ? Easier programmatic content creation ? As an exchange/transmission format, a bit similar to gltf ?<br></p><p><br></p><p><a href="http://www.web3d.org/x3d/content/examples/Basic/ScriptConformance/">http://www.web3d.org/x3d/content/examples/Basic/ScriptConformance/</a></p><p>has good examples to test scripting.

See gears.x3d/gears.json and load DOM through importDocument. And independent test would help. I am not sure which of my X3DCanvases gets loaded first and I am using absolute indexing, so it could be the XML loaded one that is failing. Basically, we need a good way to load scripts coming in through JSON I think, and the only real way I know how to do it is eval or cobweb with JSON to XML conversion and VRMLscript. If Cobweb could use the VRMLscript from JSON or DOM, that might be ideal.</p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">This is with cobweb 2.4.</p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">John</p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Sent from <a href="https://go.microsoft.com/fwlink/?LinkId=550986" target="_blank">Mail</a> for Windows 10</p><p class="MsoNormal"><u></u> <u></u></p><div style="border-width:1pt medium medium;border-style:solid none none;border-color:rgb(225,225,225) -moz-use-text-color -moz-use-text-color;padding:3pt 0in 0in"><p class="MsoNormal" style="border-width:medium;border-style:none;border-color:-moz-use-text-color;padding:0in"><b>From: </b><a href="mailto:yottzumm@gmail.com" target="_blank">yottzumm@gmail.com</a><br><b>Sent: </b>Thursday, December 1, 2016 12:32 AM<br><b>To: </b><a href="mailto:andreasplesch@gmail.com" target="_blank">Andreas Plesch</a>; <a href="mailto:brutzman@nps.edu" target="_blank">Don Brutzman</a>; <a href="mailto:roy.walmsley@ntlworld.com" target="_blank">Roy Walmsley</a><br><b>Subject: </b>FW: loading X3D DOM.
