Hello,

Is it possible to parse multiple formats in a single log file ?

For ex : My log file can write different type of data belonging to different sub-system within the same application which is writing the logs.

The first line of the log can be as below :

[composite\_name: \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*] [composite\_version: 1.0] [endpoint\_name: \*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*] JMSMessageConsumer\_init:[destination = \*\*\*\*\*\*\*\* (payload = 1)]:Failed to create managed connection: java.lang.ClassCastException  
javax.resource.spi.ResourceAdapterInternalException: Failed to create managed connection: java.lang.ClassCastException

A few lines later, the log can be like below :

\<JCABinding=\> \*\*\*\*\*\*\*\*\*\*\*\*\*\* [\*\*\*\*\*\*\*\*\*\*\*::insert(\*\*\*\*\*\*\*)] Could not invoke operation 'insert' against the 'db' due to:  
BINDING.JCA-11616  
DBWriteInteractionSpec Execute Failed Exception.  
insert failed.

--\> Is it possible to parse such data within the same file ?  
--\> Is it possible to extract fields based on a keyword search??

For example :  
If a field has some specific data as part of huge stack like : "Caused by...\*\*\*\*"  
Then I would like to extract that specific line into another field
