Re: Still trying to validate an XML Schema

Hi Ted,

you'll see the XML source in the browser because Jetty sends the file 
with content-type=application/xml. To change the content type to 
xhthml+xml (which allows the browser to render the HTML as expected), 
open the HTML file in eXide, change the content-type combobox in eXide 
in the upper right corner from XML to HTML. Don't forget to save and 
reload using CTRL+R.

The Javascript error is in fact a warning. It's triggered by line 10:

     if (SVG_Data.readyState = 4) {

I assume it should be double equation signs:

     if (SVG_Data.readyState == 4) {

With a single equation sign, you don't test for equality - instead 
you're trying to assing the value 4 to SVG_Data.readyState. That's a 
common bug so it has its own error message - doing an assignment in the 
conditional expression instead of a equation test is a bug in almost all 
cases. I assume the assignment fails, thus the bool value is false in 
every case, and the code inside the if clause is never executed.

Regarding the "windows service" issue, sadly i can't help - i don't use 
eXist on Windows.

Greetings,
Florian
