Is there any possibility to include multiple conditions in 'test' attribute expression in <xsl:if>
tag of XSLT like
<xsl:if test="$var='ab' | $var='bc' | $var='ca' ">
</xsl:if>
I am getting an error as "Expression must be evaluated to a node-set".
Is there any possibility to code such multiple conditions in <xsl:if>
Tag?
Can anyone explain how can we achieve this multiple condition validation for the following tags in
<xsl:if>
in test attribute expression
<xsl:for-each>
in select attribute expression
<xsl:template>
in match attribute expression
?
<xsl:if test="$var='ab' | $var='bc' | $var='ca' ">
This is wrong -- you are using the XPath union operator |
on boolean values.
Solution: use the XPath or
operator:
<xsl:if test="$var='ab' or $var='bc' or $var='ca' ">
The above XPath expression (the value of the test
attribute) can be optimized, so that only one comparison is made and no or
is necessary:
<xsl:if test="contains('|ab|bc|ca|', concat('|', $var, '|'))">
