How to match two lines separated by newline?

I have a PDF whose textual representation (according to the rules preview) contains the two lines

Code: Select all: ... 1 Mar 21 28 Mar 21 ...

I can match the individual lines, but I don't know how to match the two lines with the newline in between.

Also, each date seems to start always on the second column of the line (note the space before 1 Mar 21). Can I somehow say in a match: "Match from the beginning of the line a space and then my custom text"?

Thanks for pointers!

If you enter a space in to a pattern, it will match any amount of space or newlines.

Thanks Paul.

To find with more certainty the intended match, is there a way to specify to match only newlines and not other whitespace?

Not really. Is that really needed in this case? You can try matching a specific occurrence if it's something that occurs multiple times in the file. Or match the line before and/or after to include more context.
