in thread Looking for appropriate Regex

Well, I parsed variably structured strings, consisting of different characters, like: letters, numbers, space, brackets, minus, comma from a CSV file.

The CSV file is a database output in the form of an Excel worksheet, saved as a CSV file. The first coloumn contains fields with a series of letters and numbers, called IDs, i.e.

|A B 1234 a <1>| |A B 1234 a,b|

In order to look up the image files corresponding to the IDs, I parse the IDs of the CSV file into a text file, which will later be opened as a file handle. During the parsing of the IDs the comma of comma separated letters (like: a,b or c,e) which are part of the ID is accidentally (?) deleted.

Just to point out the context: The parsing is the first step of a file import, see nodes:
