I was able to get this to work, but while reading about it, I see all
these little tips and recommendations regarding being efficient and not
creating nodes when you only need strings.
In this code my goal was meet of deciding if the length of all the text
concatenated together is greater than 30.
<xsl:variable name="strings" as="xs:string"><xsl:value-of
select="answers"/></xsl:variable>
<xsl:variable name="slen" as="xs:integer"><xsl:sequence
select="string-length($strings)"/></xsl:variable>
<xsl:for-each select="answers">
<xsl:choose>
<xsl:when test="$slen gt 30">
etc...
I tried various combinations of using the <<concat()>> function,
<<xsl:sequence>>, and <<xsl:value-of>>. This is what ended up working.
Is there a "better" way to do this?
Thanks
