Hi All, I am just learning about XML, and I have a strange problem with an exercise in my book. I am trying to load an XML document with JavaScript, but after it is loaded, browser complains that RootElement is null. The filename is definitely correct and the XML file is "well-formed." I can load other XML files from other exercises using the same JavaScript just fine (just changing the filename in the load() method). Could someone please take a look at the code below, and see if they can find a problem. I am stumped! Thanks a lot!!! The XML:
The HTML and JavaScript:

Barry, There is a problem with specifying xml namespace,<i>dt</i> in your xml file at the root element, Book. Change <b>urn</b> to <b>uri</b>. xmlns:dt="uri:schemas-microsoft-com:datatypes" Hope it will work.

YanNaing, Thanks for your reply! But, if I load another XML file that uses "dt:dt" it works fine, which makes me think there is some other problem. Nevertheless, I will try your suggestion to see if it makes a difference. Thanks, Barry
YanNaing, Now I am a little confused. I changed the "dt t" to "dt:type" in my XML code, and it worked just like you said it would. But, I have many other examples (all from the book) that I have been using successfully with "dt t". Do you or anyone else have any ideas as to why this is? Thanks, Barry

Barry, That is an interesting story. Would you give me one of the other working example using dt t. Let me take a look at it. BTW, what brower and version are you using? Here is the good tutorial, I hope it would help your learning. web page
Here is one that works using "dt:dt". I am using IE6.0. Thanks for the tutorial!

Barry, Good News. The problem is at <PublicationDate dt:dt="date">12/20/99</PublicationDate>. In fact, the format of the element content,"12/20/99". The schema that allow the date data type is "CCYY-MM-DD". I think this is MS Xml schema specification. The correct one is like <PublicationDate dt:dt="date">1999-12-20</PublicationDate>. good luck,
Ohhhhhhhhhhhhhhhhhh!!! I see! Yes, that is the problem! I am using BEA XML Editor. It has a parsing feature, but I guess it doesn't actually validate the datatypes. I guess that is asking to much... Thank you very much for your help!

You are very welcome....
I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
