Success! Got it to work! Copy and pasted from the quote/editor. I had to edit the path to the data file to: "http://localhost/IIQ/some.xml".... Why would I have to specify the specific path if the the file, some.xml, was in the same directory as the index.html?
Will this code work on my original file that isn't formatted as xml (i.e., it's just html)? (I'll try it and see.) If you think it won't work, what can I do to get my original code to read the html file - basically to do what you did with this xml file?
As always, thank you all!
