How to pick a record in XML file

Question

 Hi All!

I have xml file:

 <?xml version="1.0" encoding="utf-8" ?>

- <!-- Document created at: 6/19/2010  -->

- <Notes>

- <Note date="22/06/2010" time="09:32" type="none">

  <Date>22/06/2010</Date>

  <Time>09:32</Time>

- <Text>- <![CDATA[ My first note. ]]>  </Text>

  </Note>

- <Note date="23/06/2010" time="09:32" type="none">

  <Date>23/06/2010</Date>

  <Time>09:32</Time>

- <Text>- <![CDATA[ My second note. ]]>  </Text>

  </Note>

- <Note date="24/06/2010" time="09:32" type="none">

  <Date>24/06/2010</Date>

  <Time>09:32</Time>

- <Text>- <![CDATA[ My third note. ]]> </Text>

  </Note>
