fo:table-row is missing child elements Exception

I have a piece of code defined in my xslt file in order to format some info for the printing purposes.
But sometimes, the object which I am transforming against this xslt, doesn't have the myAccountInfo
tag's child elements and I get the exception . But I want something like this :
if the elements exists then print the info otherwise just print "not available" or "Unknown"
So if firstName element is not available then put "unknown" in place.

Can some body please help me about it and tell me how I can deal with it.

Please put a little example code if possible.

Here is a piece of code I am using:

<xsl:template match="myAccountInfo">
<fo:table xmlns:fo="http://www.w3.org/1999/XSL/Format" table-layout="fixed" font-size="10pt"
font-family="Arial, Helvetica, sans-serif">
<fo:table-column column-number="1" column-width="1.75in"/>
<fo:table-column column-number="2" column-width="1.75in"/>
<fo:table-column column-number="3" column-width="1.75in"/>
<fo:table-column column-number="4" column-width="1.75in"/>
<fo:table-body>
<fo:table-row>
<fo:table-cell xmlns:fo="http://www.w3.org/1999/XSL/Format">
<fo:block xmlns:fo="http://www.w3.org/1999/XSL/Format" text-align="center"
color="#0000FF" padding-before="2pt" padding-bottom="3pt">
<xsl:value-of select="firstName"/>
</fo:block>
</fo:table-cell>
<fo:table-cell xmlns:fo="http://www.w3.org/1999/XSL/Format"> > <fo:block
xmlns:fo="http://www.w3.org/1999/XSL/Format" text-align="center"
color="#0000FF" padding-before="2pt" padding-bottom="3pt">
<xsl:value-of select="lastName"/>
</fo:block>
</fo:table-cell>
<fo:table-cell xmlns:fo="http://www.w3.org/1999/XSL/Format">
<fo:block xmlns:fo="http://www.w3.org/1999/XSL/Format" text-align="center"
color="#FF0000" padding-before="2pt" padding-bottom="3pt">
<xsl:value-of select="emailAddress"/>
</fo:block>
</fo:table-cell>
<fo:table-cell xmlns:fo="http://www.w3.org/1999/XSL/Format"> > <fo:block
xmlns:fo="http://www.w3.org/1999/XSL/Format" text-align="center"
color="#FF0000" padding-before="2pt" padding-bottom="3pt">
<xsl:value-of select="zipCode"/>
</fo:block>
</fo:table-cell>
</fo:table-row>
</fo:table-body>
</fo:table>
</xsl:template>

and the error I am getting is :

com.user.infra.CustomeException: xml transform error -- org.apache.fop.fo.ValidationException: :823:-1: Error(823/-1): fo:table-row is missing child elements.
Required Content Model: (table-cell+)
at com.user.infra.prt.printInit(PrtUtil.java:271)

I will really appreciate for the help!

I don't see how your example causes your error message, since the
fo:table-row does contain fo:table-cell.

Also, it's not necessary to repeat the FO namespace declaration so
often. Once at the top of your XSLT stylesheet should be sufficient
unless you are overriding the prefix elsewhere in your stylesheet.

Since you have fo:table-cell and and you have repeated namespace
declarations, if this really is the code causing the error message,
there's a very faint possibility that there's a bug in FOP such that
it's checking for equality of objects corresponding to namespace
declarations rather than checking for equality of namespace name URIs.
