Accept the quote style used by the declared event source
For 4781 events formatted like the repository's Windows Event Log Security 4781 example, XML attributes use single quotes (for example, <Data Name='TargetSid'>), while all four expressions here require a double quote before >. Consequently the rex commands leave these fields null, and the subsequent where match(target_sid, ...) removes every event. Use the fields already extracted by the Windows TA or make these expressions accept either XML quote style.
