Abstract

A method of parsing print stream data including the steps of intercepting a data file from at least a portion of the print stream data, reading at least a portion of the data file and determining if said data file is of a format having subset formats.

Claims

1. A method of parsing print stream data, comprising:

intercepting a data file from at least a portion of the print stream data;

reading at least a portion of said data file;

determining if said data file is of a format having subset formats, if said data file is of a format having subset formats that said data file is defined as a data file that may be recognized;

determining if the format of said data file is one of recognized and not recognized;

issuing an affirmative answer if said format is recognized;

issuing negative answer if said format is not recognized; and

issuing an answer which indicates that said format may be recognized if said format may be recognized.

2. The method of claim 1, further comprising:

receiving a command to parse said data file;

parsing said data file; and

producing an extracted file.

3. The method of claim 2, further comprising returning said extracted file.

4. The method of claim 2, wherein said extracted file is in an XML format.

5. The method of claim 1, further comprising spooling at least a portion of the print stream data to form said data file.
