Groovy Script to assert multiple values in an XML response received on querying DB from SOAP UI

I am trying to retrieve some data from db and based on the response, I have to pass or fail a test case. I have to do this each time I query the db

I am able to make the connection to the db and get the response. However, not quite sure on how to assert the values from the response

Tried to use Script Assertion but not able to figure out as I am completely new at this

<Results>
<ResultSet fetchSize="10">
    <Row rowNumber="1">
        <T1>TEXT1</T1>
        <T2>TASK1</T2>
        <T3>Value1</T3>
        <T4>xyz</T4>
      </Row>
       <Row rowNumber="2">
        <T1>TEXT2</T1>
        <T2>TASK2</T2>
        <T3>Value1</T3>
        <T4>ABC</T4>
      </Row>
     </ResultSet>
<Results>

From the above response, on the first step I will have to assert that "TASK1" exists and the "Value1" exists with in the same set followed by the "TASK2" and "Value1"

Please let me know if this is vague so that I can try to modify my query
