Sample RegEX for Pattern Matching OCR -

Quick Fields Pattern Matching and Regular Expressions

Updated April 9, 2019

asked on April 9, 2019 • Show version history

Hi All

Working on a new QF OCR job. Wanting to use Pattern Matching against full page OCR to pull "string" of data from the OCR text.

We normally use Zone OCR, however our source files for this are somewhat inconsistent layout wise so zone OCR is too specific.

See attached snippet.

Want the values after:

Carrier Code: - 4 digits, I have this one working

PARS#: - wanting the full string

Port of Entry: want the first 3D, and then the multiword string after the -

ETA: date string and a time string

Submitted By: just the string (could be multi word)

Hoping someone can give me a few pointers and I can build on those examples.

PARS#: 471347926923062R0

PARS\s*#:\s*([A-Z,a-z,0-9]*)

Port of Entry: 427 - NIAGRA FALLS

Use two regular expressions to capture the 3 digits and then the word(s).

Port of Entry:\s*(\d{3})

Port of Entry:\s*\d{3}\s*-\s*([\w\s]+)

ETA: 04/08/2019 08:24 PM

Again, use two regex to capture the date and time elements as tokens.

ETA:\s*(\d{2}/\d{2}/\d{4})

ETA:\s*\d{1,2}/\d{1,2}/\d{4}\s*(\d{2}:\d{2}\s*\w{2})
