Hello,
I need to produce some fixed format files from XML input. This means that I have
to put in default values in place of optional elements missing from the input
XML.
The construct I am using (in about 20 places in my transformation) is:
<xsl:choose>
<xsl:when test="optional-element"><xsl:value-of
select="optional-element"/></xsl:when>
<xsl:otherwise>default-value</xsl:otherwise>
</xsl:choose>
This works, but seems to run slowly. I am using Xalan 1.0.
Does anyone know of a better (or faster) way to do this?
Regards,
John
