How to capture multiple lines in rex

HI all,

I am trying to capture multiple lines between two strings in my log data. But so far have not been able to figure out a solution.
the log data is as follows:

'calls': 'apfsae.providers.economic.china_jobs_data_provider.ChinaJobsProvider',

'db_connection': 'providers/database_connection :: qtrewd_iq',

'db_view_name': 'adweh.V_datayes_china_recruitment',

'calls': 'apfsae.providers.mappings.company_id_to_barra_mapper.BbToBarraMapper',

I want to capture lines starting from ChinaJobsProvider to 'calls':
Thank you !

Do you mean something like this

| rex "(?ms)ChinaJobsProvider'(?<lines>.*)'calls"

Hi I used this but it matching with every record even if it contains this data or not.

Try it like this so it is less greedy

| rex "(?ms)ChinaJobsProvider'(?<lines>.*?)'calls"
