RE: Java cannot parse what the DOM creates??

[robert_gary]

Here is my actual code... Notice that the next Node is set to ^Lhello.
The DOM creates the following document...
<?xml version="1.0" encoding="UTF-8"?>
<mytag>hello &#12;</mytag>

Then, when it goes to parse it I get

It seems unintuitive to me why the DOM would go to the effort to
transform my character if it can't read it. Shouldn't any document the
parse creates be parsable?

I presume you mean &12; -- the trailing semicolon is important.

See the XML Specification's description of "numeric character
references".
This is absolutely standard XML. Any parser *should* accept it unless it
appears in a place where that character is not legal (in the middle of
an
element name, for example).
