xsl empty element: how to do?

[adrian]

Hi

I'm having the following problem:

im my xml file there is an element called <gebdatum>22.09.79</gebdatum>
(date of birth in english). this might be full (like in the example) or
empty.
in case it is empty I want to have some text saying that this data is
missing.

I tried like this but it only shows me that text "Keine Daten
vorhanden", but not the data where it exists:
_____________________________________________
<xsl:for-each select="gebdatum">

<xsl:if test="gebdatum=(.!='') ">

<font color="green">Keine Daten vorhanden!</font>

</xsl:if>

<xsl:if test="gebdatum!=(.!='') ">

<xsl:value-of select="gebdatum"/>

</xsl:if>

</xsl:for-each>
_______________________________________

I've also tried with
<choose>
<when>
</when>
<otherwise>
</otherwise>
<choose/>

and it didn't work too

What am I doing wrong?

Any help kindly regarded.

Trying too hard :-) The simplest route is usually the best. This is the Tao
of XSLT :-)

forget about xsl:for-each brrrr..... the best method of that checking is the
string-length() function using. You have to check: xsl:if
test="string-length(element/element/text())!=0". It guarantees performing in
cause of empty element and nonexisting element both.
