this thread, but I hope to capture comments from all messages in
the thread. My comments only apply to the web browser (HTML5)
environment.<br>
<br>
First, any Script tag (in any case) will be handled by the web
browser, and the web browser will parse content before anything
else. If you really need to independently parse some tags, you
will need to "read" it into a JavaScript variable and handle it
that way. If it's in the page file, it will be parsed.<br>
<br>
There was a suggestion to use "text/x3dscript" or some other
string. The W3C has something to say about this at
<a class="m_8095493740017175402m_-7056022351321710558moz-txt-link-freetext" href="https://www.w3.org/TR/html5/scripting-1.html#the-script-element" target="_blank">https://www.w3.org/TR/html5/scripting-1.html#the-script-element</a>.
The value of the type attribute must either be<br>
<ol>
<li>omitted</li>
<li>JavaScript MIME type</li>
<li>"module"</li>
<li>any other valid mime type</li>
</ol>
<p>So the use of an invalid MIME type is not technically valid
HTML. This may cause a problem with some browsers or validators;
or present future problems if that string is ever defined to
have a particular meaning.</p>
<p>X3DOM does not have X3D scripting. If you need scripting to
correctly process an X3DOM environment; then you need to do it
in HTML5 Javascript. X3DOM does not process the Script tag, that
is done by HTML5. While X3DOM parser could recognize that tag,
it does not; hence, none of the X3DOM methods are available to
handle interactions on a Script node (a Script tag parsed into
DOM).</p>
<p>The X3D Script / HTML5 Script tag name conflict is a
long-standing and known issue. To my knowledge no work has been
done to break the conflict. <br>

<p class="MsoNormal">I have a problem with this file in X3DOM,
because as far as I can tell, the SFNode fields (the node, not
the field) do not have getFieldValue for point etc. as a
function, for example (but one can double check me). In other
words, I don’t think this node is an X3DOM node.<u></u><u></u></p>

That’s as clear as I can get. I think this might be because
