Help required on XSLT Conditional Mapping

Question

Hi,
We need help on XSLT mapping in BPEL based on a condition. We are transforming from OAG format to a client specific format. We need to map a single tag (but repetitive) on the left hand side (OAG) to different tags on the right hand side. The same tag on the left hand side repeats with different values. Depending on the value the mapping to the right hand side varies. The left hand side (OAG) looks something like this.
<PARTNER>
<PARTNRID>2002</PARTNRID>
<PARTNRTYPE>Supplier</PARTNRTYPE>
<ADDRESS>
<ADDRLINE index="1">2000 Century Way</ADDRLINE>
</ADDRESS>
</PARTNER>
<PARTNER>
<PARTNRID>204</PARTNRID>
<PARTNRTYPE>BillTo</PARTNRTYPE>
<ADDRESS>
<ADDRLINE index="1">90 Fifth Avenue</ADDRLINE>
</ADDRESS>
</PARTNER>
Please note that the tag PARTNER and it's underlying tags appear twice in the XML file.
Based on the value in the tag PARTNRTYPE, the mapping to the right hand side differs. If the value is 2002, PARTNRID should map to Supplier ID on the right hand side and if the value is 24, PARTNRID should map to BillTo ID on the right hand side. The right hand side should look something like
<Supplier>
<SupplierID>2002</SupplierID>
<Address>2000 Century Way</Address>
</Supplier>
<BillTo>
<BillToID>204</BillToID>
<Address>90 Fifth Avenue</Address>
</BillTo>
Please let us know how to achieve this. Your help is much appreciated. Thanks in advance.
Thanks,
Prasanna

Hi Prasanna ,
I am not an expert but what about this:
<SUPPLIERID>
  <xsl:value-of select="/PARTNER/PARTNRID[../PARTNRTYPE = '2002']"/>
</SUPPLIERID>
<BILLTOID>
  <xsl:value-of select="/PARTNER/PARTNRID[../PARTNRTYPE = '24']"/>
</BILLTOID>or
<xsl:choose>
  <xsl:when test="/PARTNER/PARTNRTYPE = '2002'">
    <SUPPLIERID>
      <xsl:value-of select="/PARTNER/PARTNRID"/>
    </SUPPLIERID>
  </xsl:when>
</xsl:choose>
<xsl:choose>
  <xsl:when test="/PARTNER/PARTNRTYPE = '24'">
    <BILLTOID>
      <xsl:value-of select="/PARTNER/PARTNRID"/>
    </BILLTOID>
  </xsl:when>
</xsl:choose>Regards Pete
