How can I extract only the second column (pids of processes)?

How can I extract only the ninth column (pathnames of files)? (pathnames can contain any character allowed by Linux and ext4 file systems)

My real command is

    $ sudo lsof -u t  | grep -v "wineserv" | grep REG  |   grep "\.pdf" | grep  "string"

where I would search for records whose first column "COMMAND" isn't `wineserv`, and fifth column "TYPE" is `REG`, and whose ninth column "NAME" contains `.pdf` and `string`.

Prefer bash, awk or Python solutions (and maybe Perl, but I don't know Perl, so won't be able to verify if it is correct or modify it later)
