Because Joe's Pizza is missing the url node, I don't get a pipe, which
throws off my columns. Is there a way to test for all possible nodes,
and where any are missing, to insert a character?
Very often in XSLT, your process is mainly data-driven. The program
reacts to input.
In your example, however, you want to guarantee a certain structure that
may be missing in your input. A simple way to guarantee this structure
is to code it in your program:
<xsl:template match="business">
<xsl:copy>
<name><xsl:value-of select="name"/></name>
<address><xsl:value-of select="address"/></address>
<url><xsl:value-of select="url"/></url>
</xsl:copy>
</xsl:template>
This would be step 1 in what Martin already suggested for 1.0.
You may also simply leave out the element constructors (like
<name>...</name>) and separate your <xsl:value> elements by
<xsl:text>|</xsl:text> to guarantee the pipe-structure. This
works for 1.0, too.
