Hi ArcSight Community,
I am working on developing a custom XML FlexConnector parser to handle event logs from a specific application. I have created the parser configuration file, but I need assistance with validating the mappings, token types, and overall configuration to ensure it captures and categorizes events correctly.
Below is a sample of the XML content I am working with, and I have changed the data to dummy values without altering the format:
```xml
<?xml version="1.0"?>
<Sag:EventLogList xmlns:Sag="urn:swift:sag:ns_Sag">
<Sag:EventLog>
<Sag:LogSysTime>01/01/2023 12:00:00.0000</Sag:LogSysTime>
<Sag:LogSequence>1234567</Sag:LogSequence>
<Sag:ApplicationId><![CDATA[dummy_app]]></Sag:ApplicationId>
<Sag:LogCorrelationId>ABC-1234-5678-90abcdef-123456-7890-10.0.0.1:12345-67890</Sag:LogCorrelationId>
<Sag:PlugInName>Sag:SN-I</Sag:PlugInName>
<Sag:EventNumber>2000</Sag:EventNumber>
<Sag:EventName>Response primitive sent</Sag:EventName>
<Sag:EventSeverity>Information</Sag:EventSeverity>
<Sag:EventClass>Message</Sag:EventClass>
<Sag:LogUnitName>None</Sag:LogUnitName>
<Sag:LogMessage><![CDATA[Response primitive sent.

]]></Sag:LogMessage>
<Sag:LogProcess>dummy_process</Sag:LogProcess>
<Sag:RecordVersion>1</Sag:RecordVersion>
</Sag:EventLog>
</Sag:EventLogList>
```
Here is the parser configuration I have developed so far:

I would appreciate any feedback on the configuration, particularly:
1. Correctness of token definitions and mappings to ArcSight fields.
2. Proper usage of severity mapping.
3. Accuracy of the event categorization and the example custom_mappings.csv content.
4. Any other best practices or improvements you might suggest.
Thank you for your assistance!
