I just modified the SQL you sent and put the XML data in # table and wow it is much faster.

INSERT INTO #xmlData

SELECT CAST((SELECT '' + line

FROM #output

FOR XML PATH(''),

TYPE).value('.[1]', 'varchar(max)') AS XML) AS FormattedXML

SELECT item.ref.value('(Property/text())[1]', 'nvarchar(200)') AS Folder,

item.ref.value('(Property/text())[2]', 'nvarchar(500)') AS Access,

item.ref.value('(Property/text())[3]', 'nvarchar(200)') AS UserGroup

FROM #xmlData

AS Sub

CROSS APPLY XmlData.nodes('/Objects/Object') AS item (ref);

Thanks for all your help !
