RE: [xsl] adding unique values to a drop-down list

["Katie McNally" <kmcnally9 at hotmail dot com>]

I am trying to display unique brokers in a drop-down for each loan with a 
channel of "WH".

My for-each statement which loops through the loans seems to work only when 
the first loan in the xml has a channel of "WH".  If it does, all unique 
brokers are displayed in the drop-down.  If the channel of the first loan in 
the xml is something other than "WH", no brokers are displayed.

Any suggestions?

My for-each statement and sample xml are listed below:

<xsl:for-each select= "Loan[not(Id=preceding::Id) and string(Name) and 
string(Id) and Channel='WH']">
        <xsl:sort select="Name" order="ascending"/>
        <xsl:sort select="Id"/>
        <option value='{Id}'>
        <xsl:call-template name="displayBroker">
	     <xsl:with-param name="name" select="Name"/>
	     <xsl:with-param name="id" select="Id"/>
	</xsl:call-template>
        </option>
</xsl:for-each>


<Loan>
  <LoanId>0000003071</LoanId>
  <Channel>RET</Channel>
  <Name>Broker 1</Name>
  <Id>432123</Id>
</Loan>
<Loan>
  <LoanId>0000003072</LoanId>
  <Channel>WH</Channel>
  <Name>Broker 1</Name>
  <Id>432123</Id>
</Loan>
<Loan>
  <LoanId>0000003073</LoanId>
  <Channel>WH</Channel>
  <Name>Broker 1</Name>
  <Id>432123</Id>
</Loan>
