Abstract

A data processing method comprises receiving an electronically parseable document, scanning the document according to at least one predefined rule to determine if the document is suspicious, and, if the document is determined not to be suspicious, parsing the document with a first parser, and, if the document is determined to be suspicious, parsing the document with a second parser.

Claims

1. A data processing method comprising receiving an electronically parseable document, scanning the document according to at least one predefined rule to determine if the document is suspicious, and, if the document is determined not to be suspicious, parsing the document with a first parser, and, if the document is determined to be suspicious, parsing the document with a second parser.

2. The method according to claim 1, wherein the first parser is faster than the second parser.

3. The method according to claim 1, further comprising, while scanning the document, converting the document from a first format to a second format.

4. The method according to claim 1, further comprising monitoring the performance of the first parser, and adjusting at least one of said predefined rules in dependence on the monitoring.

5. The method according to claim 1, further comprising monitoring the performance of the first parser, and creating a new rule in dependence on the monitoring.

6. The method according to claim 1, further comprising monitoring the performance of the second parser, and in a predefined circumstance, discarding another document prior to parsing, if said document is of a particular form.

7. A data processing apparatus comprising a scanner for receiving an electronically parseable document, and for scanning the document according to at least one predefined rule to determine if the document is suspicious, a first parser for parsing the document if the document is determined not to be suspicious, and a second parser for parsing the document if the document is determined to be suspicious.

8. The apparatus according to claim 7, wherein the first parser is faster than the second parser.

9. The apparatus according to claim 7, wherein the scanner is arranged, while scanning the document, to convert the document from a first format to a second format.

10. The apparatus according to claim 7, the apparatus being designed to monitor the performance of the first parser and to adjust at least one of said predefined rules in dependence on the monitoring.

11. The apparatus according to claim 7, being designed to monitor the performance of the first parser and to create a new rule in dependence on the monitoring.

12. The apparatus according to claim 7, the apparatus being designed to monitor the performance of the second parser and in a predefined circumstance, to discard said document prior to parsing, if said document is of a particular form.

13. A computer program element comprising computer program code which when loaded in a data processing apparatus, configures said data processing apparatus to perform a method comprising receiving an electronically parseable document, scanning the document according to at least one predefined rule to determine if the document is suspicious, and, if the document is determined not to be suspicious, parsing the document with a first parser, and, if the document is determined to be suspicious, parsing the document with a second parser.

14. A computer program element according to claim 13 stored on a computer readable medium.

15. The computer program element according to claim 13, wherein the first parser is faster than the second parser.

16. The computer program element according to claim 13, wherein said method further comprises, while scanning the document, converting the document from a first format to a second format.

17. The computer program element according to claim 13, wherein said method further comprises monitoring the performance of the first parser, and adjusting at least one of said predefined rules in dependence on the monitoring.

18. The computer program element according to claim 13, wherein said method further comprises monitoring the performance of the first parser, and creating a new rule in dependence on the monitoring.

19. The computer program element according to claim 13, wherein said method further comprises monitoring the performance of the second parser, and in a predefined circumstance, discarding another document prior to parsing, if said document is of a particular form.
