How can I do an in list option for XSLT

Question

In Pseudo code

If Domain inList(GB,US,ES,FR Then
   Print This Html
Else
  Print This HTML
EndIf

Thanks

Answer 1

Try using the xsl:choose. (Also see the spec here) It provides a basic if/else functionality. EDIT- I did test and it works:

<xsl:choose>
  <xsl:when test="domain = 'GB' or domain = 'US' or domain = 'ES' or domain = 'FR'">
    print this html
  </xsl:when>
  <xsl:otherwise>
    print other html
  </xsl:otherwise>
</xsl:choose>

Answer 2

This is a*very* general form, but where you don't know the list at design-time, so long as you can get a reference to a nodeset which represents the list you can do a simple test like:

<xsl:when test="$listset/item[@property=$variable]">

where say $variable = /foo/bar/@property and $listset = /foo/list for XML

<?xml version="1.0"?>
<foo>
  <bar property="gb" />
  <list>
    <item property="gb"/>
    <item property="us"/>
  </list>
</foo>

Answer 3

If you are using XSLT 2.0 given the file

You can use something like this:
<xsl:template match="list/item">
Property [<xsl:value-of select="@property"/>] html
</xsl:template>

<xsl:template match="list/item[some $x in ('us', 'gb') satisfies $x eq @property ]">
Property [<xsl:value-of select="@property"/>] HTML
</xsl:template>


Answer 4

Another solution, not mentioned by the current 3 answers is to have a string of the options against which you are comparing the value of domain. Then the following XPath expression (in the @test attribute of either <xsl:if> or <xsl:when> evaluates to true() exactly when the value of domain is one of the delimited values in the string (we use a space for delimiter in this concrete example):

  contains(' GB US ES ', concat(' ', domain, ' '))

Here we suppose that there are no spaces in the value of domain. If this cannot be guaranteed, the XPath expression can also verify this requirement:

  not(contains(domain, ' '))
and
  contains(' GB US ES ', concat(' ', domain, ' '))
