[Configuration] Call me a moron, but I just can't make it work!
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.
So far, nothing I've tried has worked:
***CODE***
XMLPropertyListConfiguration sigh = new
XMLPropertyListConfiguration(plistPath);
sigh.load();
System.out.println(sigh.containsKey("SandwichFillings")); //this
prints "true" - great!
//What I actually want, is the "SidebarTitle" string. When I try:
sigh.containsKey("SidebarTitle");
//or
sigh.containsKey("SandwichFillings.Dictionary.SidebarTitle");
//or any other combination that I could think of - I get false.
***/CODE***
If I save the file with a different name, I can open it and see that
the information has all been copied correctly.
I just haven't been able to figure out how to access/edit information
in the file.
For the past two days I've been trawling the internet and trying
everything I could think of, but I am yet to succeed.
Is what I want to do even possible? If so, please tell me how!
Please! It's been driving me insane.
This is an example of the files I'll be reading (currently I want to
get key = SidebarTitle, and change its value).

I'm using Netbeans 6.01 with Mavenide, Maven2. I get no errors at
compile time, no error during my attempts to get the key/value (unless
one counts "null" when you know it's damn-well there as an error!).
Thank you for taking the time to read my message,
Mike

Your problem is that you are searching for the value of an element, not
the element name, i.e. there are no elements named SndwichFillings,
Dictionary or SidebarTitle. Your element names are all named "key". I
can never remember how to filter based on the value of an element of a
key using the default expression language. With XML I use the XPath
expression lanaguage.

Hi Oliver, thanks again for that!
I've got both of the files, and set them up in Netbeans.
When I run the TestXMLPropertyListConfiguration.java file, as below, I
get the following output:
...
TestXMLPropertyListConfiguration test = new
TestXMLPropertyListConfiguration();
test.setUp();
...
Which runs:
...
protected void setUp() throws Exception
{
config = new XMLPropertyListConfiguration();
config.setFileName("/Users/faceleg/Downloads/
test.plist.xml"); //this is where I've put the file for now
config.load();
}
...

Re: [Configuration] Call me a moron, but I just can't make it work!

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

I've removed that line from the plist.xml file, and it loads now.
I should be able to learn enough from the test methods now, I don't
need that line.

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.

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.
