Remove XML tags from XML element in Oracle

Question

Hi,
I have a requirement where I have to remove all the xml tags from xml element with banks, currently I'm using replace 4 times to replace all different types of xml tags, performance is really bad. is there any better option to remove xml tags from xml data leaving the actual data. please find the example data below.
select
TO_CLOB(REPLACE(REPLACE(REPLACE(REPLACE
('<Concatcolumn><ConcatGroupID>MyText Data goes here </ConcatGroupID><ConcatGroupID>Data agian</ConcatGroupID></Concatcolumn>','<ConcatGroupID>'),'<Concatcolumn>'),'</ConcatGroupID>',';'),';</Concatcolumn>')) AS Concatcolumn
from dual
**************Out put*************
MyText Data goes here ;Data agian

Answer 1

One way is to use xquery:
SQL> with t as
select xmltype('<Concatcolumn>
                      <ConcatGroupID>MyText Data goes here </ConcatGroupID><ConcatGroupID>Data agian</ConcatGroupID></Concatcolumn>'
   ) xml from dual
select xmlquery('string-join(//text(), ";")' passing xml returning content).getclobval() xml from t
XML                                                              
MyText Data goes here ;Data agian
