[jdom-interest] Re: problem with JDOM / Namespaces (Brett McLaughlin)

[Humphrey Sheil]

Some more information on the topic of colons in Elements and Attributes.  I
was having the same problem and  am working against a CVS snapshot from
8/3/2000 7 pm GMT.

Results:

org.jdom.Verifier

2 methods affected - checkAttributeName and checkElementName

checkAttributeName  does specific checks for xml:space and xml:lang but
rejects anything else.

checkElementName rejects all Elements with a name containing a colon.

I commented out both checks and I can now create my documents just fine
(because I've shortcircuited the validation).  Now when I try and read them
in using SAXBuilder I get a null pointer, however when I tried to debug this
by loading it using DOMBuilder instead, it worked just fine - DOMBuilder
didn't throw any exceptions and I can process the XML file correctly.
Here's the stack trace, looks like it's xerces that can't handle the colons?
