Hi Tamas, Not sure I'm correct, but I think what you're suggesting won't work, as I can't split by string2 separately - I only want to find substrings, that are in between the combination "string1[10-15 characters]string2" and "string3". As an example, I would need to find:
string1XXXXXXXXXstring2DATAstring3 string1XXXXstring2DATAstring3 but there's lots more mentions of string1 and string2 in the data set that don't follow this pattern, for which I don't want to extract the following substring.
