Re: XML to Plist

Multiple File Open Strategy

Hello. I have a working implementation using Grand Central dispatch queues that open a file and compute an OpenSSL DSA hash, writing out the hash to a new "side car" file for later verification. I would like to open multiple files at the same time, but based on some logic that doesn't "choke"

Following on the same path as suggested to take a step back and examine what you want to happen, launch Property List Editor, create a Property List file, and manually add the items from your XML scenarios to determine what you really want to happen for each item you encounter. On 12/28/2010 10:34
