Reading XML file from package!!

Question

HI,
I have an xml file with two HIERARCHY levels with Global and local
<global1> company</global1>
<global2> address </global2>
<global3>name </global3>
<global4>position</global4>
and
-- *<loca1l/>*
<local2> CEO</local2>
-- *<local3/>*
<local4> supervisior</local4>
Now i have a package which reads this file and loads into the table.
My Question :- In the unknown Local depth 1 and local Depth 3 i want to display company(global depth 1). So when package reads the XML file, if there is any unknown tags then it should load company or read company of the gloabl depth 1 into the table. Any idea or logic would be great helpful.
I appricate it thank you so much!!

                    <local1/>
                    <local2> CEO</local2>
                    <local3/>
                    <local4> supervisior</local4>
                 </data>') xml from dual
select x.column_value.getstringval()
from t,
      xmltable('for $i in data/*
                 return
                    if (contains($i/name(), "local") and empty($i/text()))
                    then
                      element {$i/name()} {$i/../*[name()=concat("global",ora:replace($i/name(),"local",""))]/text()}                     
                    else $i' passing xml) x
X.COLUMN_VALUE.GETSTRINGVAL()                                                  
<global1>company</global1>
