Don't display table part if element not present ????

[Patrick]

Hello and please forgive my newbieness,

Say I have one section of xml like this with 3 elements and the
following has 4 elements;

<deploy_info>
<datatype1>ADCP Velocity measurements</datatype1>
<datatype2>ADCP Temperature</datatype2>
<datatype3>ADCP Performance Data</datatype3>
</deploy_info>
<deploy_info>
<datatype1>ADCP Velocity measurements</datatype1>
<datatype2>ADCP Temperature</datatype2>
<datatype3>ADCP Performance Data</datatype3>
<datatype4>Seabird Microcat Data</datatype4>
<deploy_info>

And I have a table like such;

<table>
<tr>
<td><xsl:value-of select="datatype1"/></td>
</tr>
<tr>
<td><xsl:value-of select="datatype2"/></td>
</tr>
<tr>
<td><xsl:value-of select="datatype3"/></td>
</tr>
<tr>
<td><xsl:value-of select="datatype4"/></td>
</tr>
</table>

Assuming I already know how to do the xsl:for-each. How or can I even
tell xsl to not display the <tr> through </tr> for <datatype4> if it is
the first group that is selected for writing?

Thanks for any ideas on this,
Patrick

It might suffice to iterate over all child elements (XPath *) e.g.

<xsl:for-each select="deploy_info">
<table>
<tbody>
<xsl:for-each select="*">
<tr><td><xsl:value-of select="."/></td></tr>
</xsl:for-each>
</tbody>
</table>
</xsl:for-each>

Then there is xsl:if e.g.

<xsl:if test="datatype4">
<tr><td><xsl:value-of select="datatype4"/></td></tr>
</xsl:if>

Thanks for the pointer. That second one looks more intuitive to me. Is
there an advantage or disadvantage between the methods?

the first group that is selected for writing?

I'm not entirely sure what that phrase is intended to mean in this
context. Could you give us a more specific example?

Joe,

Doesn't matter now. I got it to work using an "if test=" told to me by
another poster. Thanks for asking though. I have to work on my xml
vocabulary so I can more clearly explain myself.

A useful technique is to include a (small!) specific example of what
you're starting with, what you want out -- and if you're asking for
debugging assistance -- a (small!) runnable stylesheet that demonstrates
the problem and its erroneous output. That way, if someone's confused by
the description they can look at the code.

I'm pretty sure I did with the original post. But thanks for the reminder.
