Question

I need to be able to store a node set in variable and then perform more filting/sorting on it afterward. All the examples I’ve seen of this involve either using XSL2 or extensions neither of which are really an option.

I’ve a list of hotels in my XML doc that can be sorted/filtered and then paged through 5 at a time. I’m finding though I’m repeating alot of the logic as currently I’ve not found a good way to store node-sets in xsl variable and then use xpath on them for further filtering/sorting.

This is the sort of thing I’m after (excuse the code written of the top of my head so might not be 100%):

<xsl:variable name="hotels" select="/results/hotels[active='true']" />
<xsl:variable name="3_star_or_less" select="/results/hotels[number(rating) <= 3]" />
<xsl:for-each select="3_star_or_less">
  <xsl:sort select="rating" />
</xsl:for-each>

Has anyone got an example of how best to do this sort of thing?

Answer 1

Try this example:

<xsl:variable name="hotels" select="/results/hotels[active='true']" />
<xsl:variable name="three_star_or_less"
              select="$hotels[number(rating) &lt;= 3]" />
<xsl:for-each select="$three_star_or_less">
    <xsl:sort select="rating" />
    <xsl:value-of select="rating" />
</xsl:for-each>
