SQL & PL/SQL

Hi all,

I am trying to loop through XML but whatever I put behind PATH I always get no rows returned,

here is my SQL :

  select *
    from xmltable('*/text()' passing xmltype('<?xml version="1.0" encoding="utf-8"?>
<TaskResult>
  <Sample>
    <SampleId
      SampleId1="Reference"
      SampleId2="ACIN"
      SampleId3=""
      SampleId4=""
      SampleId5=""
      SampleId6=""
      SampleId1Description="ID 1"
      SampleId2Description="ID 2"
      SampleId3Description=""
      SampleId4Description=""
      SampleId5Description=""
      SampleId6Description="" />
    <Task
      Name="ACIN"
      InternalId="T1319"
      StartTime="2015-05-19T08:29:18"
      EndTime="2015-05-19T08:47:38"
      State="Completed" />
    <Method
      Name="IM1_AI"
      MethodId="ACIN"
      MethodInternalId="M37"
      Version="32"
      ReleaseState="Released"
      IsApproved="False" />
    <Product
      Name=""

      Version=""
      ReleaseState=""
      IsApproved="" />
    <Account
      LogonName="PredefinedUser"
      FullName="Administrator" />
    <Resultset
      Approved="False" />
    <ResultResult

      InstrumentSerialNr="B502477066"
      InstrumentTypeInfo="T90"
      InstrumentInternalId="I6" />

</TaskResult>')
