Output multiple regex matches

Question

Hi All,

I am analyzing a log file which has the following form:

"Text text text KEYWORD 123 Text Text Text KEYWORD 345 Text Text Text KEYWORD 678"

I would like to extract KEYWORD 123, KEYWORD 345, KEYWORD 678 and have every match in a separate column. There could be also more occurrences than only 1-3 - I need to output them all.  Have tried it with RegEx (KEYWORD) (.*) ) but RegEx is returning only the FIRST match and the remaining keywords in the input string are ignored.

Do you have an idea?

Regards,

BlendingFan :)

To split to columns in one step, you will need to know the maximum number of occurrences of keyword.  If you don't know this, we can still make this work, but will need two tools.

First, I tweaked your regex slightly:

(KEYWORD\s[^\s]*)

This should do basically the same thing but is more restrictive so it shouldn't accidentally incorporate additional unintended characters.

Using this with the "Tokenize" option in the RegEx tool we can split out the data to a finite number of columns.  You could set this to a very large number so you always have data, although some columns will be NULL.

If you don't want to deal with NULL columns, you can Split to Rows and then use a Cross Tab tool to create the columns.  For this you may want to use a RecordID tool before RegEx so that you can get back to 1 line per each.
