You don't need a regular expression. The build field function has subfuntions you can call as part of the pattern. Substring is one of them. It looks like this: =092 \\$aFAMILY DVD {245$a.substring(0,3)} See: https://secure-web.cisco.com/1tq6oE7RScj-DJJO2yNe0C6SX17ibkkhqxXOsr0-EsB-ltVUgvob6MzcgaOV_l2jDILPfnjSq2PVwbq_oUMezBMQ7lyv-K43uLHL-isE82P7Hc5NnNY4QFEV_Licsyinp_N1RapZA_7auK2rJ1kT5HBFb18s-yzgcwoI1hVrT1z-USI3dEQGPTSi_Lgk-FLLkPShPJzbTmQHh8sElc8HN-WWLYV5i8brWxbh49lUfsTa_ekLEBewP6W0FhLNU1DVyCnAmO7NfKXrgb_o1Jyl3-820_R-ljfMV6Hl3rictuaa8wms-eitFIq8ygVf81aMJNskso9sBBWInALSoFjYjqIRRt1em9lZOehQgPPag43ENbSUU7n1zrKUNYOlwma8iqWMNYkfjArqQJ8f44LOT0pLUQtuMwYI-mC7mioqlrLRONQ9xtXUAKNrZT0c-k_uaUm5fmu7SIHa1Bv8rmHAIjg/https%3A%2F%2Fblog.reeset.net%2Farchives%2F1853 --tr -----Original Message----- From: MarcEdit support in technical and instructional matters <[log in to unmask]> On Behalf Of Jawahir Javaid Sent: Friday, July 24, 2020 1:06 PM To: [log in to unmask] Subject: [MARCEDIT-L] regex in build new field Hi, I am trying to create a new 092 field with the first 3 letters of the title using the Build New Field function of MarcEdit. Is there a regular expression to capture this? So far, I have the pattern: =092 \\$aFAMILY DVD {245$a} This pulls the whole title. How do I limit to the first 3 letters of the 245 field? Or would you reccomend another approach to accomplishing this?
