select only some elements and attributes

Hi, What's the best way to only select some elements and attributes using
xslt? For example, the xml source looks like:

<product sku="123465-45">
   <title>Mutton and Rice Dog Food</title>
   <description sku="2345-67">Everything needed for your pet's
health</description>
   <price>25.99</price>
   <available_date>2000-12-25</available_date>
   <size>large</size>
   <weight>40lbs</weight>
   <vendor>
      <company>Nutro Max</company>
      <street>15 Industrial Blvd</street>
      <city>Reno</city>
      <state>NV</state>
      <zip>56381</zip>
      <phone>583 233-4598</phone>
   </vendor>
</product>

The output I want should be like:

<product sku="123465-45">
   <title>Mutton and Rice Dog Food</title>
   <price>25.99</price>
   <weight>40lbs</weight>
   <vendor>
      <company>Nutro Max</company>
      <phone>583 233-4598</phone>
   </vendor>
</product>

Thank you very much!
