In an XML document I have some address data..
<zip>08001</zip>
<zipPlus xsi:nil="true" />
and
<zip>08002</zip>
<zipPlus>4512</zipPlus>
On only want to bother displaying the zip plus value if there is a value to use. (for the purposes of this example, I don't care if its a correct zip plus format or not)
Trying to use the following snippet in an XSLT never seems to work right, and I think it has to do with how I am checking for the xsl:nil value
<EmployerZipCode>
<xsl:value-of select="zip"/>
<xsl:if test="zipPlus != @xsl:nil">
<xsl:value-of select="'-'"/>
<xsl:value-of select="zipPlus"/>
</xsl:if>
<xsl:value-of select="$sepChar"/> <!--this is a comma -->
</EmployerZipCode>
The results I get are always
08001,
08002,
not
08001,
08002-4512,
What is the proper way to check for nil-led elements in XSLT? Are there any other ways to get around this problem and get the result I want?

If an element has the xsi:nil attribute specified, it indicates that the element is present but has no value, and therefore no content is associated with it. If an XML schema has defined the nillable attribute as true, it is mapped as a required attribute that takes a Boolean value.
The xsi:nil="true" attribute is defined in the XML instance document. The xsi:nil="true" attribute indicates that, although the element exists, it has no content. Note that the xsi:nil="true" attribute applies to element values, and not to attribute values.
Specifies the format pattern. Here are some of the characters used in the formatting pattern: 0 (Digit) # (Digit, zero shows as absent)
<xsl:if test="not(zipPlus/@xsi:nil='true')">
