Well, the caps are in the sami format like this

<SYNC Encrypted="true" start="13967">9cb25a9dc6d0f588d3a29c82923fc284595f 9bb77b7420a7600655df43d32355dabf25bb721e857e67591c 0e24154924</SYNC>
etc...

So you only need to decrypt each <sync> which is rijndael 128 cbc (you need the key and iv) and for the example returns "News Headquarters in New York,";
