I'm trying to get this extraction for the filename to work via transforms.conf but it isn't working. Any ideas?

[My_source_type]

REPORT-file= extract_file

 

[extract_file]

REGEX =<Data Name='TargetFilename'>.*\\\\(?<file>[\S\s+]*)<\/Data>

FORMAT = file:$3

Hi @TheBravoSierra 

[My_source_type]
REPORT-file= extract_file

[extract_file]
REGEX = \<Data Name\=\'TargetFilename\'\>.*\\(?<file>[^<]+)
FORMAT = file::$1

Hi @TheBravoSierra ,

Can you check if the following works?
<Data Name='TargetFilename'>.*\\(?<file>[\S\s+]*)<\/Data>
