I'm using Sun's JAXP.JAR to parse an XSL file. I submitted the questions
below to XML-INTEREST at SUN.COM. To date, I have not received any reply.
I'm wondering if this is something that has been addressed in JDOM? Or if
anyone on this list knows the answer to my questions below? Or if anyone on
this list knows were to go to get my questions answered?
Thanks in advance.

I realized that as I was parsing the DOM I could pass the current attribute
value to a method that would convert the value to " " if the current
value equaled "160".
The same can be done for text nodes. The value of the text node can be
passed to this method. When the method encounters a value of "160" it
returns " " instead.
Once the method returns I print the value of the node just to make sure. And
it does look correct.
I then cast my document as an XmlDocument so that I can call the
XmlDocument.write() method to write the document to disk.
The problem is that the " " gets converted to "&#160;".
When viewed in a browser I see " ". It appears that the browser
converts the "&" to an "&" and then returns " " instead of
interpretting this as a non-breaking space.
Now that I've figured out how to get the value correct in the DOM, how do I
get it to disk in exactly the same format?
