Hello,
I'm using XSLT2.
I need to construct a complex string in a variable. I wanted to use XSLT
instructions for this, not pure XPath. I'm struggling with coercing the
result of the <xsl:variable> body to a single xs:string, not a sequence of
xs:string:
<xsl:variable name="var" as="xs:string">
<xsl:text>prefix</xsl:text>
<xsl:value-of select="'part1'"/>
<!-- follows more complex code producing further fragments of desired
result string -->
</xsl:variable>
This gives me the error message (Saxon HE 9): "A sequence of more than one
item is not allowed as the value of variable $var ("prefix", "part1")"
Of course, I could declare the variable as xs:string+ and then use
string-join( $var, '' ) on every use of $var, or create another variable that
holds the concatenated result of $var.
<xsl:variable name="var" as="xs:string">
<xsl:value-of>
<xsl:text>prefix</xsl:text>
<xsl:value-of select="'part1'"/>
<!-- follows more complex code producing further fragments of
desired result string -->
</xsl:value-of>
</xsl:variable>
