Se è un semplice testo e non XML , puoi semplicemente usare REPLACE .
Ad esempio,
SQL> WITH DATA AS
2 (SELECT '
3 <COLLECT_PARALLELGRAMMAR1>global.grxml</COLLECT_PARALLELGRAMMAR1>
4 <COLLECT_INPUTMODES>voice dtmf</COLLECT_INPUTMODES>
5 <CONF_INPUTMODES>dtmf</CONF_INPUTMODES>
6 </ROW>
7 </properties>
8 <?xml version="1.0"?>
9 <properties>
10 <ROW>
11 <MODULE_NAME>main_menu_phone</MODULE_NAME>
12 <MODULE_DESCRIPTION>Main Menu for Customers with silver membership</MODULE_DESCRIPTION>
13 <MODULE_TYPE>phone</MODULE_TYPE>' str
14 FROM dual
15 )
16 SELECT REPLACE(str, '</properties>
17 <?xml version="1.0"?>
18 <properties>', '') new_str
19 FROM data;
NEW_STR
