Easy XML config files?

[Chris]

We have XML config files in our app. To get data out of the files, I
find myself writing SAX content handlers over and over.

Is there a quick and easy way for me to avoid this? It would be nice to
have a class like java.util.Properties, except it works with XML.

java.util.Properties DOES work with XML.
Look at the loadFromXML method

Properties.html#loadFromXML(java.io.InputStream)>

I have a library to implement something like this.
The source language, however, is not exactly XML, but Unotal.
Unotal is a - in my opinion - simplified and improved XML.

Say, the file »source.uno« contained:

< x =< a = 2 b = 3 > y = 4 A B C >

Then,

public class Main
{ public static void main( final java.lang.String[] args )
{ final de.dclj.ram.notation.unotal.RoomSource source =
de.dclj.ram.notation.unotal.RoomFromModule.roomFrom
( new java.io.File( "source.uno" ));
java.lang.System.out.println( source );
java.lang.System.out.println( source.get( 2 ));
java.lang.System.out.println( source.get( "x" ) );
java.lang.System.out.println( source.getRoom( "x" ).get( "a" )); }}

prints

< x =< a =2 b =3 >y =4 A B C >
C
< a =2 b =3 >
2

The experimental library ram.jar is alpha-released under the GPL:

That is neither simplified nor improved over XML.
It may be a better communication protocol for specific circumstances,
but if you understood the goal of XML, then you would realize your
unotal falls far short.

Thanks, didn't know that. Properties, though, only handle name/value
pairs, and it's not possible to have multiple values for one name:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
<comment>yo</comment>
<entry key="name">value</entry>
<entry key="name">a second value</entry> NOT ALLOWED
</properties>

That's one reason we use XML instead of .properties files.

I had been wonderring, why do you flag your
messages for 'no archive'?

(As an aside, they always seem like very
technical answers - worth being available
in later searches..)

Still further off-topic. What /I/ would like is an "x-archive-only" flag. I
have no objection to Google (or anyone) archiving my posts; I don't like having
them exploited by organisations like (but not limited to) Google to lure and
deceive users into dependence on their ad-ridden websites....

(Not that I'd bother using that flag if it did exist -- at least, not unless
quite a few other people did too.)

So do it! Invent and describe an x-licence header for NNTP
