Hi
I got a Commons Configuration question. Is there some easy way to format the
XML output from an XMLConfiguration?
Reading a config file and saving it works very well. However each time the
file is saved a couple of empty lines are inserted between random elements.
The file is of course still usable, but it looks quite bad when editing by
hand after beeing saved a few times.
XMLConfiguration stores the DOM tree obtained from the parser. When
saving, the tree is written using an XSLT identity transformation. This
should normally not mess up the formatting.
However, if properties are modified or added, the nodes created by these
operations typically do not match the format of the other nodes which
causes poor results when writing the configuration back to disk. Also
creating a new XML configuration produces unformatted documents.
Does anybody have an idea how a better formatting could be implemented?
In the early days we used a library like dom4j for XML handling. This
produced nice-looking documents, but the price was an additional
dependency. I don't think we should go back.
