empty table problem

[fraagol]

Hi all,
I have a XML document like this:

...
<documents>
    <document>
        ...
    </document>
    <document>
        ...
    </document>
</documents>

and a xsl like this:

<fo:block space-after="12">
                        <fo:table table-layout="fixed" width="100%" border="1" border-style="solid" border-color="#55A0dd">
                                <fo:table-column />
                                <fo:table-body>
                                                <xsl:apply-templates select="documents/document" />
                                </fo:table-body>
                        </fo:table>

                </fo:block>
....

<xsl:template match="documents/document">
                <fo:table-row>
                        <fo:table-cell>
                                <fo:block font-size="8pt">
                                        <xsl:value-of select="name" />
                                </fo:block>
                        </fo:table-cell>
                </fo:table-row>
        </xsl:template>

the problem is when the tag <documents> doesn't contain any <document> tag, so the table header is created but no row added. error:
fo:table-body is missing child elements.

How could I manage this so when no document tag exists inside documents tag nothing would  be displayed?
thanks!

Put the fo:block inside an xsl:if; i.e., put
<xsl:if test="documents/document"> before the <fo:block> and put
</xsl:if> after the </fo:block>.

Also, you can use "space-after" with fo:table, so the fo:block isn't
strictly necessary.
