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?
