It's better to do it without the Result Tree Fragment as intermediate step:
<xsl:variable name="xtest" select="department"/>
Is the variable needed? You can of course directly test on the element:
<xsl:if test="string(department)">
is true if any character is contained in <department/>
</xsl:if>
<xsl:if test="normalize-space(department)">
trims white space characters and tests after this normalization
</xsl:if>
The comparison with the empty string '' is not needed.

Subject: XSL Element testing whether empty, or not!
Hello group,
newbie question:
How can you test whether a Element contain information or not? I mean
something like the DB command "is not Null" // "is null".
Example:
data.xml
case 1) <department>Elektro</department>
case 2) <department />
I want to have the word Department in front of the value as soon as the
<department>is not empty</department>.
I figured out that the string-length(./department/text()) is 19 as soon
<department />. If <department>is not empty</department> is > 19.
So I have written the following xsl (knowing that is a work around but not a
solution).
<xsl:variable name="xtest">
<xsl:value-of select="string-length(./department/text())"/>
</xsl:variable>
<fo:block>
<xsl:choose>
<xsl:when test="$xtest>19">Abteilung: <xsl:value-of
select="./department/text()"/>
</xsl:when>
<xsl:when test="$xtest<20">
<xsl:value-of select="./department/text()"/>
</xsl:when>
</xsl:choose>
Is there a better way to do it?
Mit freundlichem Gruss,
