Thanks again for the help.

I found a solution to make the stylesheet approach work for all BIG5
browsers.
For details you may want to see this posting with more samples:

And since its a Javascript API, they might not even care on XSLT.


I was able to prove that your explanation is correct by getting this
Firefox
error console message:

Warning: A call to document.write() from an asynchronously-loaded external
script was ignored.
Source File: http://stamm-wilbrandt.de/en/xsl-list/gmap/s.ff.html
Line: 0


For that I made use of the Javascript XSLTProcessor directly in HTML page:
http://stamm-wilbrandt.de/en/xsl-list/gmap/s.ff.html

That page loads stylesheet "s.xsl", XML document "s.xml" and then
transforms.

As far as I can tell the problem with Firefox is likely caused by an
attempt to use the DOM's document.write method to inject a script
element dynamically. That is done by the Google maps code you include it
seems.
As Firefox's XSLT implementation directly renders the result tree of the
XSLT transformation is does not support document.write in the result
document (see
https://developer.mozilla.org/en-US/docs/XSL_Transformations_in_Mozilla_FAQ#What_about_document.write.3F

).

I don't see an easy workaround, unless Google provides an API or a way
to use the maps code without relying on document.write.
