DELETEXML
を使用する XPath //*[not(text())][not(*)]
を探します テキストも子も含まない要素を見つけるには:
Oracle11gR2スキーマのセットアップ :
CREATE TABLE table_name ( xml ) AS
SELECT XMLTYPE( '<MESSAGE>
<LOCATIONS>
<LOCATION_ID>9999</LOCATION_ID>
<LOC_TYPE>S</LOC_TYPE>
<NAME>Test Location</NAME>
<PHONE_NUM>08 </PHONE_NUM>
<LAST_MODIFIED_BY/>
<LAST_MODIFIED_DATE/>
<POS_CODE/>
</LOCATIONS>
</MESSAGE>' ) FROM DUAL;
クエリ1 :
SELECT DELETEXML(
xml,
'//*[not(text())][not(*)]'
).getStringVal()
FROM table_name
結果 :
| DELETEXML(XML,'//*[NOT(TEXT())][NOT(*)]').GETSTRINGVAL() |
