As you have discovered, the nodes are not in the document, to distinguish between NULL and empty string.
As for XSLT, you could always do:
<xsl:template match="row">
<xsl:value-of select="column1"/>,<xsl:value-of select="column2"/>,<!-
+- etc etc -->
</xsl:template>
In this way, non-existant elements will get stringified into the empty string.

Perl is strongly typed, it just has very few types (Dan)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
