Try something like this:
<xslt:value-of
select="count(/inventory//warehousecode[not(preceding::warehousecode = .)])"/>
Someone else might come up with something more efficient ...

Thanks for your help in my previous post! Given the below xml,how can I get
the
the number of unique warehouse codes? Do I need to use <xsl:key>?
<inventory>
<item>
<warehousecode>BA</warehousecode>
<item>bolt</item>
<quantity>34</quantity>
</item>
<item>
<warehousecode>BA</warehousecode>
<item>nail</item>
<quantity>50</quantity>
</item>
<item>
<warehousecode>AC</warehousecode>
<item>tack</item>
<quantity>5</quantity>
</item>
<item>
<warehousecode>BA</warehousecode>
<item>hammer</item>
<quantity>10</quantity>
</item>
<item>
<warehousecode>AD</warehousecode>
<item>screwdriver</item>
<quantity>60</quantity>
</item>
<item>
<warehousecode>AB</warehousecode>
<item>wrench</item>
<quantity>13</quantity>
</item>
</inventory>
Desired output:
Number of unique warehouse codes: 4
