Hello again,
I've spent some time with the test class, and managed to get to the
data I need.
I still don't have any idea how to use
"config.getProperty("stringleadingtoproperty")" though.
And thus, I suspect I will be unable to use
"config.setProperty("stringleadingtoproperty", "newproperty")"...
This is what I used to find the data I need:
***CODE***
public void testNestedArray()
{
String key = "SandwichFillings";
Object array = config.getProperty(key);
// root array
assertNotNull("array not found", array);
ObjectAssert.assertInstanceOf("the array element is not
parsed as a List", List.class, array);
List list = config.getList(key);
System.out.println(list.size());
assertFalse("empty array", list.isEmpty());
assertEquals("size", 1, list.size());
XMLPropertyListConfiguration o =
(XMLPropertyListConfiguration) list.get(0);
Iterator k = o.getKeys();
while(k.hasNext()){
key = (String) k.next();
if(o.getProperty(key) instanceof String){
System.out.println(o.getString(key));
}
System.out.println();
}
}
***/CODE***
Output is:
***OUTPUT***
1
self
html
Original
High
Default
SIDE TITLE
utf-8
***/OUTPUT***
When I saw that I almost cried, I was so happy.
So my question now is, what string would one use to access SIDETITLE
directly?
It is in a Dictionary, which is in an Array - the property of
SandwichFillings.
I've tried a few strings, but I don't really know the syntax, or what
is possible so it's like stumbling around in the dark.
Could someone please let me know how I am able to 1) access this data,
2) change the value.
Thank you for your time and patience,
Mike

Hi,
I'm writing a program that must load, search, edit and save Mac OS
X plist files.
I was attempting to use apple's NS* foundation classes, but I
couldn't work out how to write to the plist files (maybe I'm just
stupid).
I searched around the internet and was overjoyed to find
apache.commons.configuration.
I've played with it for the past few days, trying to figure out
how I'm meant to get data out of the plist files I'm working with.
Have you looked at the unit tests for the configuration project?
Commons projects generally have pretty good unit test coverage,
which means that there is almost certainly an example of reading a
plist file and extracting a value from it in there somewhere.
In general, the unit tests for a project are a good source of
examples when the explicit user examples and tutorials don't cover
what you need to do.
The unit tests can be fetched from the Apache subversion system
using the url that is in the left-hand navigation bar.

You can find the test class for XMLPropertyListConfiguration at [1].
It reads a test file [2] and evaluates the properties contained.
I assume your concrete problem is due to the fact that the value of
the "SandwichFillings" key is an array, which obviously complicates
things. Have a look at the testNestedArray() method in [1], which
deals with nested arrays.
Querying the value of an array should result in a List. You can dump
the content of this list to see how it is structured.
