Interfacing StyledDocument and XML

Question

Hello,
I'm trying to make an xml editor, but am stumped on the javax.swing.text.StyledDocument interface. The problem is that DefaultStyledDocument isn't suited to store xml, and HTMLStyledDocument is well, html. What I want is a document class that can easily interface with the myriad of xml technologies out there (e.g. the org.w3c.dom classes)... so I think I need to create my own, as well as an editor kit. [shudder  :-o ]
Has anyone attempted this / seen tutorials / have tips ?
Thanks in advance

The Document model only stores one character ("\n") for each new line entered.
When you do a statement like:
String str = textPane.getText();
The newline characters in the document are replaced with the newline string for the target operating system:
a) for Unix - "\n"
b) for Windows - "\r\n").
Therefore, the length of the String in Windows will always be greater by the number of lines in your Document.
The way I have gotten around this problem is to change the End-Of-Line string that is added when using the getText() by using the following code:
textPane.getDocument().putProperty( DefaultEditorKit.EndOfLineStringProperty, "\n" );
Note: if you ever intend to write the contents of the text pane to a file then your code should be something like:
a) String eol = textPane.getDocument().getProperty( DefaultEditorKit.EndOfLineStringProperty );
b) textPane.getDocument().putProperty( DefaultEditorKit.EndOfLineStringProperty, "\n" );
then before writing to the file you would do:
c) textPane.getDocument().putProperty( DefaultEditorKit.EndOfLineStringProperty, eol );
