    Reading duplicate tags under its parent tab

      Here is the sample XML, i intend to use XMLTABLE to read the structured XML
      <emptype desig="PAT" confirmed="NO"/>
           <projname>Oracle BI migration</projname>
           <projname>Oracle XML parsing</projname>
      <emptype desig="M" confirmed="YES"/>
           <projname>Midwest US</projname>
           <projname>Automotive Insurance for US</projname>

      Based on the condition
      if the employee is confirmed as YES, then get the different project he/she has worked along with the employee id

      Its is required to fetch the details conditionally,
      so the above xml would yeild the below result columns

            Yeah, you posted 30 minutes ago. We're not a chat room either.

              - Does your database have a version?
              - Where does the input XML reside?

              The structure is not very friendly, but you can do it like this :
              SQL> with sample_data as (
                2    select xmltype('<employee>
                3  <empid>101</empid>
                4  <empname>Mike</empname>
                5  <emptype desig="PAT" confirmed="NO"/>
                6  <projects>
                7  <projname>Oracle BI migration</projname>
                8  <projname>Oracle XML parsing</projname>
                9  <projmanagerid>102</projmanagerid>
               10  </projects>
               11  <empid>102</empid>
               12  <empname>Sophie</empname>
               13  <emptype desig="M" confirmed="YES"/>
               14  <projects>
               15  <projname>Midwest US</projname>
               16  <projname>Automotive Insurance for US</projname>
               17  <projmanagerid>103</projmanagerid>
               18  </projects>
               19  </employee>') xmldoc
               20    from dual
               21  )
               22  select x.*
               23  from sample_data t
               24     , xmltable(
               25         'for $e in /employee/empid
               26          where $e/following-sibling::emptype[1]/@confirmed = "YES"
               27          return
               28            for $p in $e/following-sibling::projects[1]/projname
               29            return element r { $e, $p }'
               30         passing t.xmldoc
               31         columns empid    number       path 'empid'
               32               , projects varchar2(40) path 'projname'
               33       ) x
               34  ;
                   EMPID PROJECTS
