Help with regular expression
« on: December 29, 2012, 07:31:29 PM »
Testing PDF Explorer.
I have several hundred invoices in PDF format. I would like to extract the invoice number to an Info Field.
In clear text the invoice number is identified like this:

Fakturanr.: XXXX

It is the 4 digit invoice number I would like to extract, and if possible validate if the invoicenumber has changed into 5 digits which it will do over time.

Can anyone help me with the proper Regular Expression string for this?

Kind regards Frank

If the invoice number is numeric only, try this one:


The number will go into the 2nd capturing group, as exemplified in the attached screenshot where it is being extracted to a custom field named number.

Regarding the 5 digits validation. What kind of feedback you have in mind when that occurs?
