AFAIO the correct syntax is: text2.getFirstChild(). This is the function you

The correct syntax according to DOM/SVG is 'text2.firstChild' anything else
is not compliant.
"The script engine interface technology available on Netscape for the
Macintosh does not support writable attributes on interfaces. To work around
this limitation, Adobe SVG Viewer supports additional "get/set" methods for
each DOM interface attribute. For cross-browser script compatibility you
should always use these methods instead of the writable attributes listed
below. For example, to read from and write to the attribute nodeValue on the
Node interface, use the methods getNodeValue and setNodeValue, instead."
Does this same syntax work in Batik?
Yes this will work in Batik, but this is _not_ compliant with
the DOM/SVG ecma binding. Also I would expect that the above referenced
problem is easily solved by using the Adobe script engine rather than
the browser native script engine.
Admittedly this is also in some sense not compliant with the SVG spec
but one attribute in the Adobe namespace is much less of an issue than
dozens of calls (to be honest I can't think of any way this violates
the DOM/SVG specification - well I suspose they should have used the
Adobe engine and allowed the option of switching to the less compliant
browser engine).
BTW you can have your content use the Adobe interpreter with the following
on the outermost SVG element:
xmlns:a3="http://ns.adobe.com/AdobeSVGViewerExtensions/3.0/";
a3:scriptImplementation="Adobe"
But at this point we are really off topic and probably better discusses
in the yahoo SVG group.

If I change "text2.firstChild()" to "text2.firstChild" then it works. I
assume the second form is the correct one? And that Adobe is just more
forgiving...

Subject: interperter exception
I'm trying to do some scripting within Batik and am getting an exception
when trying to call a function on an element. Anyone have any idea why?
(The same SVG works in the Adobe plugin.)
