Re: xsl:when, xsl:otherwise question?

hi,

I am new in xsl, please help me to figure out why my
following code doesnt work:
here's the xml data:

<pb><e><a>hello</a></e></pb>
and it can be also <pb><e></e></pb>

so actually I want to separate 2 cases, one when tag a
doesnt exist and the other one is when it exists.

<xsl:choose>
 <xsl:when test="a">
  <tr><td>null</td></tr>
 </xsl:when>
 <xsl:otherwise>
  <tr><td>not null</td></tr>
 </xsl:otherwise>
</xsl:choose>

The result I got when tag 'a' exists is ok. I got
"null" displayed but when tag 'a' doesnt exist, i got
nothing display.

could you please let me know if the syntax i used is
correct and what i am supposed to do please.

thanks a lot

Dinh Tran
