Question

Suppose the xml input is

<Tasks>
 <Task Name="Add2">
   <Dependency Name="S1"/>
 </Task>
 <Task Name="Min2">
  <Dependency Name="Dev1"/>
  <Dependency Name="Extra"/>
  </Task>
<Tasks>

I want the outcome as

Add2   S1
Min2   Dev1
Min2   Extra

How to achieve this using Xpath in a Sql Sproc

Answer 1

Some of your previous questions has been about SQL Server so….

declare @xml xml = '
<Tasks>
 <Task Name="Add2">
   <Dependency Name="S1"/>
 </Task>
 <Task Name="Min2">
  <Dependency Name="Dev1"/>
  <Dependency Name="Extra"/>
  </Task>
</Tasks>'


select T1.N.value('@Name', 'varchar(max)') as TaskName,
       T2.N.value('@Name', 'varchar(max)') as DependencyName
from @xml.nodes('/Tasks/Task') as T1(N)
  cross apply T1.N.nodes('Dependency') as T2(N)
