How to retrieve version and encoding info from SAX parser

I want to have access to the version and encoding info in a parsed XML document (when using SAX2). Who knows how this works?
If not possible with SAX2, what other solutions are there?
Second question: how to retrieve comments in XML files?
Thanks in advance!

thanks for answering, but ...
LexicalHandler is fine for retrieving the comments,
but does not give me the encoding (specified by
encoding="UTF-8") and version (specified by
version="1.0").
I am feeding my parser with a byte stream, the parser
resolves the correct encoding and i want to have
access to this value!!hi , It is unlikely that you will get the encoding and version . This is being addressed by the DOM level3
, see

How to get contacts and calendar info from my old palm files

I used to use a Palm Tungsten T3. I no longer have it but until recently I still used the Palm Desktop. My computer "died" and I was able to copy all the Palm files of of it but now I have no idea how to get the contact and calendar(less important than contacts) info in some form I can use. I do not currently have any Palm software installed on my computer. I have Microsoft Windows XP on my computer now and use Outlook or Outlook Express. Does anyone have any advice for me. Thanks in advance.

How to retrieve email and contacts data from time machine from a different computer

My iMac hard disc has died and though I have everything backed up on Time Machine I am finding it difficult to access my Contacts (not on iCloud) and emails from my laptop.
I understand that they are to be found on the Time Machine backup in library/applicationsupport/addressbook and /Library/Mail/V2, but these files appear to be hidden.
From my reading it has been suggested that I use the utility Terminal, but I don’t know where to start with this – any guidance would be most welcome

How do I send my BMP info from logic to pedals and keys?

How do I send my BMP info from logic to pedals and keys?
Is it possible to sync my logic bmp with my microkorg so that my korg automatic will sync with the BMP from logic?

I'm not faniliar with the Micro, but logic outputs mtc and midi clock. The serttings are under project settings/synchronization. You'll have to set the Micro to external sync and be sending midi info from your computer to the Micro. Then if you hit play or record in Logic, the micro will chase it.

How do I get the iCloud to save and sync and upload info from both the devices on my account. Right now I can only do one

You must put each device on the Verizon cloud.
Not both lines on one.
Go and set up a my Verizon account for the second line and you will have Verizon cloud service on that line.
Oh the term "icloud" is a trademark of Apple Inc. Verizon is not Apple.
Good Luck

If you still have the receipt or other proof of purchase, you can ask Apple to send you the serial. Otherwise, bad luck mate.. Good news is, you can now buy Logic Pro 9 from App Store for just 199 USD

My Mac mini chash about one month ago and I got it back from apple, I didnt have a time michine back up for this one but in my old mac I have almost all my files, so I want to transfer all the data to the Mac mini with no problem

You can use migration assitant which is located in the Utility Folder under Applications. The compters can be connected via ethernet, fire wire, or wifi. My recommendation is not to use wifi.
You run migration assistant on both machines and you can choose to transfer everything or just data.
Another way is to use migration assistant to restore from a time machine backup.

To remove Audiobooks depending on the type of Audiobook ie a series of mp3 files you will find under music and probably have to deselect the album name to remove it. I don't have any of these as I download from Audible or I use Audiobook Builder to stictch together mp3 files into m4b files. To find these Click on Books you will immediately see a section for books (in reality ebooks). Scroll down past that and you will see Audiobooks where you can select and deselect. Deselect the required Audiobooks and Click Sync
