I have a swing application that sends commands to server and receives result in XML format. I need to transform this into HTML via XSLT and then display result HTML on the panel. The problem is that the only Swing component which is able to display HTML - JEditorPane - takes either URL or javax.swing.text.StyledDocument as a source. 
Option with URL doesn't work for me because I have to save my html as a file on the file system first and I'd like to avoid this.

So I have a gap between in-memory result of XSL transformation and javax.swing.text.StyledDocument, which can be rendered by JEditorPane or JTextPane.

How to transform one to another? Or are there any other Swing solutions to display HTML from some in-memory source(DOM or String or whatever)?

Thank you in advance for help.
