Re: [Enigma-devel] Create xml dom using java.

[Reece]

Thanks Erick,

However, I wasn't able to figure out how to implement the code.
Would you like to take a look at the code?
I can send you the file or the code is also available on Git via a 
SourceForge project.
http://sourceforge.net/projects/enigmaeditor/ (The projects SourceForge 
page.)
http://sourceforge.net/p/enigmaeditor/sourcecode/ci/cb11dd3eed66e2ecfed8d59892282d7991cedb30/tree/NetBeans%20Project/src/egle/MyFileOperations.java#l114 
(This is the class file that I'm talking about)
The method "exportXML()" contains the code I have so far.

I also have another problem that you might be able to help me with, when 
I use transformer factory/transformer to output my dom tree to an xml 
file, the transformer outputs into a single line.
Do you know how to get the transformer to output the xml file with line 
breaks and indentations(tabs)?
