Was having numerous issues with the voice xml. I think I figured out the first problem of the url. Things become clear when you leave for awhile then come back with fresh eyes.

My XML is verified with my DTD..Next up Voice XLM and XSTL..

I have found that notepad has a goto feature so I can go to the line I want,where the error is located. This only works with the wordwrap feature OFF.

I have FINALLY figured out the DTD issue I had. I decided to use an internal DTD until I have more time to change it to an external one. Externals are better IMO because you can put that DTD anywhere on the server. You can also manipulate easier than an internal DTD. One issue I have with the Topologi DTD checker is that once it sees an error it doesn't take you to it. I have to keep counting spaces over and over again until I found the error.

Update

I forgot the location of my last blog so I had to create this new one. I have finished all of my xml. I need to update it to include some suggestions Dr. Coyle had. I have been trying to figure out how to get the DTD link to work. Hopefully I can figure it out.
