If I have the following XML file:

Code:
<Catalog>
  <Patch>
    <UpdateNumber>1</UpdateNumber>
    <properties>
      <ProductName>Sample Update</ProductName>
      <PatchName>Sample_Update.exe</PatchName>
      <Description>Installs the Sample Update</Description>
      <Reboot>1</Reboot>
      <file_1 style="normal">FILEPATH</file_1>
    </properties>
    <downloads>
          <DownloadURL>LOCATION</DownloadURL>
    </downloads>
    <detection style="applicable">
        <OSType>WIN_XP</OSType>
    </detection>
    <detection style="installed"> 
    </detection>
  </Patch>
</Catalog>
How would I read each node type. For example if I just wanted to read ProductName from the properties section?
