Hi All,

I am just picking up xslt and I was wondering if I could get some
pointers. I have an xml body that looks like this:
   <location>
       <civic-address>
          <country>US</country>
          <A1>New York</A1>
          <A2>King's County</A2>
          <A3>New York</A3>
          <A4>Manhattan</A4>
          <A5>Morningside Heights</A5>
          <A6>Broadway</A6>
          <PRD>N</PRD>
          <POD>SW</POD>
          <STS>Street</STS>
          <HNO>123</HNO>
          <HNS>A</HNS>
          <LMK>Low Library</LMK>
          <LOC>Room 543</LOC>
          <FLR>5</FLR>
          <NAM>Joe's Barbershop</NAM>
          <PC>10027-0401</PC>
       </civic-address>
    </location>
   <location>
       <civic-address>
           ...
       </civic-address>
    </location>
   <location>
       <civic-address>
           ...
       </civic-address>
    </location>

I need to translate this (using xslt) to create a new element called
'street' that has the values of HNO HNS PRD A6 POD STS from one civic-
address. So the output should look like:
   <location>
       <civic-address>
          <country>US</country>
          <A1>New York</A1>
          <A2>King's County</A2>
          <A3>New York</A3>
          <A4>Manhattan</A4>
          <A5>Morningside Heights</A5>
          <street> 123 A N Broadway SW Street </street>
          <LMK>Low Library</LMK>
          <LOC>Room 543</LOC>
          <FLR>5</FLR>
          <NAM>Joe's Barbershop</NAM>
          <PC>10027-0401</PC>
       </civic-address>
   </location>
   <location>
       <civic-address>
           ...
       </civic-address>
    </location>
   <location>
       <civic-address>
           ...
       </civic-address>
    </location>

If any of HNO HNS PRD A6 POD STS are missing, they should just be
ignored. If all of them are missing, then a 'street' element should
not be created.

I am looking for tips on creating an efficient xslt for this.

TIA,
