If you just store the serial # as a key/value pair then you don't need to
directly access the XML, just use the CFPreference API's.

If I'm not understanding what you're doing and you do need to access the XML
data then you can use the CF XML API's to do that:

[BEGIN]
/*

<http://developer.apple.com/techpubs/macosx/CoreFoundation/PropertyListServi
ces/Property_List_Services_ConcTask/Conceptual/CFPropertyList-4.html>
*/
/**\
|**| Here's now to load an XML file into a property list:
\**/

// Read the XML file.
status = CFURLCreateDataAndPropertiesFromResource(
kCFAllocatorDefault,
myCFURLRef,
&xmlCFDataRef, // place to put file data
NULL,
NULL,
&errorCode);

// Reconstitute the dictionary using the XML data.
myCFPropertyListRef = CFPropertyListCreateFromXMLData(
kCFAllocatorDefault,
xmlCFDataRef,
kCFPropertyListImmutable,
&errorString);

/**\
|**| Here's now to save a property list into an XML file:
\**/

// Convert the plist into XML data.
xmlCFDataRef = CFPropertyListCreateXMLData( kCFAllocatorDefault,
myCFPropertyListRef );

// Create a URL that specifies the file we will create to hold the XML
data.
myCFURLRef = CFURLCreateWithFileSystemPath( kCFAllocatorDefault,
CFSTR("test.txt"), // file path name
kCFURLHFSPathStyle, false ); // is it a directory?

// Write the XML data to the file.
status = CFURLWriteDataAndPropertiesToResource (
myCFURLRef, // URL to use
xmlCFDataRef, // data to write
NULL,
&errorCode);

// Don't forget to release all of the CF objects you're responsible for.

[END]
