Nick, Thanks for the starter code. I'm trying to finish up the parser. I made some changes, and brought inline with other tika parser examples I have seen. I've looked over IOUtils, however I'm a bit rusty on my Java. By rusty I mean inept. The following code does iterate through the bytes and manages to find the first bit of user text. Printing to the system confims this. Unfortunately, after finding the first bit of text it's getting an exception on line 71 ( java.lang.ArrayIndexOutOfBoundsException: 2) I've attached an example PRT file.
Note: I found a simpler prefix that delineates the start of user text.
[0x01] [0x1F]

byte[] prefix = new byte[] {0x01, 0x1F};

int read;
while( (read = stream.read()) > -1) {
if(read == prefix[pos]) {
pos++;
if(pos == prefix.length) {
// found it!
int length = stream.read();
int unknown = stream.read();
byte[] text = new byte[length];
IOUtils.readFully(stream, text);
// turn it into a string, removing null termination
// assumes it's found to be utf-8
String str = new String(text, 0, text.length - 1, "UTF-8");
System.err.println(str); //<- DEBUGGING
XHTMLContentHandler xhtml = new XHTMLContentHandler(handler, metadata);
xhtml.startElement("p");
xhtml.characters(str);
xhtml.endElement("p");
}
} else {
pos = 0;
