これが私のクエリです：
SELECT t.filename, X.*
FROM XML_FILES_CLOB t,
XMLTABLE ('//Parcels/Parcel'
PASSING t.FILECONTENT
COLUMNS filename VARCHAR2(30) PATH 'filename',
Parcel VARCHAR2(30) PATH '@name') x
Where t.filename='PC373723N';
目的：XMLファイル（PC373723N）に小包の@nameを抽出します。
のXMLTable：
結果：
問題：それは小包の名前を取得しません。私はそれがXMLに存在する名前空間のためだと思う。
何か助けていただければ幸いです。
