NSKeyedUnarchiver, ASObjc - Not retrieving Values from a NSKeyedArchiver File

Benno · August 19, 2019, 9:06am

Hi,

im working on a script to parse values from a given XML File.
I know the File was saved using the NSKeyedArchiver Object, but using the NSKeyedUnarchiver Methode >>"unarchiver’s decodeObjectForKey:“FAT_ImportoRitenuta”<< as described in @ShaneStanley Book (thanks for this great Book) i get “missing value”.

Here the XML-File as whole:

Where is my thinking error? I know there are key value pairs but how can i access them easily?
Thanks to every response.

I don’t think you’re doing anything wrong — at least, it’s not responding to the obvious things here. That early FSKeyedArchiver makes me wonder if it’s not coded with NSKeyedArchiver — a quick Web search does throw up a third-party FSKeyedArchiver class.

Do you know what the value for FAT_ImportoRitenuta is in this file? There might be an unorthodox approach that works.

Benno · August 19, 2019, 1:35pm

Shane i appreciate your response.
Nice to here that i am on the right way.

The Value for the Key “FAT_ImportoRitenuta” is “54.05”. The Line underneath.

“FSKeyedArchiver” is a third-party NSKeyedArchiver class from F-Script. Some information can be found here: https://en.wikipedia.org/wiki/F-Script_(programming_language). In the Documentation in my hand there is written: “F-Script uses NSArchiver to save objects. So, objects to be saved must conform to the standard Cocoa NSCoding protocol. Files generated are standard NSArchiver files; you can use them with other applications to load archived objects using the Cocoa NSUnarchiver API”

Thx B

I suspect that documentation is a bit out of date. If I try this:

current application's NSUnarchiver's alloc()'s initForReadingWithData:theData

I get missing value, whereas this:

set {theUnarchiver, theError} to current application's NSKeyedUnarchiver's alloc()'s initForReadingFromData:theData |error|:(reference)

at least seems to return a valid keyed unarchiver. But I don’t have any luck getting anything out of it.

At a pinch, you could try parsing the XML directly, as discussed here:

So something like this:

set theDoc to current application's NSXMLDocument's alloc()'s initWithXMLString:theString options:0 |error|:(missing value)
set {theNodes, theError} to theDoc's nodesForXPath:"//string['FAT_ImportoRitenuta'=text()]/following-sibling::string[1]" |error|:(reference)
return theNodes's firstObject()'s stringValue() as text

Benno · August 21, 2019, 10:37am

Thanks Shane.
I tried your idea:

use AppleScript version "2.4" -- Yosemite (10.10) or later
use framework "Foundation"
use scripting additions

set theXMLData to (choose file)
set theXMLString to read theXMLData

set theString to current application's NSString's stringWithString:theXMLString
set theDoc to current application's NSXMLDocument's alloc()'s initWithXMLString:theString options:(current application's NSXMLDocumentTidyXML) |error|:(missing value)

set theQuery to "//string['FAT_ImportoRitenuta'=text()]/following-sibling::string[1]"

set {theResults, theError} to (theDoc's nodesForXPath:theQuery |error|:(reference)) -- query

and tried with the Code above.
The Result is an empty Array, but convalidating the XPath query with http://www.xpathtester.com/xquery for exemple i get my desired Values.
Am I loading the file wrong?

Thx

ShaneStanley · August 21, 2019, 11:52am

Probably – you’re not reading as UTF-8, but rather MacRoman, so content probably got mangled. I don’t know that you need the NSXMLDocumentTidyXML, but it probably won’t hurt.

This is a more direct way to load it from a file (assuming 10.11 or later):

use AppleScript version "2.5" -- 10.11 or later
use framework "Foundation"
use scripting additions

set theFile to (choose file)
set theDoc to current application's NSXMLDocument's alloc()'s initWithContentsOfURL:theFile options:(current application's NSXMLDocumentTidyXML) |error|:(missing value)
set theQuery to "//string['FAT_ImportoRitenuta'=text()]/following-sibling::string[1]"
set {theResults, theError} to (theDoc's nodesForXPath:theQuery |error|:(reference)) -- query
return theResults's firstObject()'s stringValue() as text
