P1 Badge 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.
