Subject: Re: [xsl] Conditional sort instruction as parameter within group && Syntactic matter of multilevel grouping | XSLT 2.0 | P2 From: "Martin Honnen martin.honnen@xxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Sun, 6 Jun 2021 18:29:09 -0000 |
Question One: The conditional sort is based on the search:highlight, if it is decimal, sort the putAmount and then incarnate the document. Notice: The "Rationale" is that currency and amount must be paired. In each search:snippet, the currency is one search:highlight while amount another. I would imagine a pure XSLT conditional sort in below manner.
===================================================== B B B <xsl:param name="sortAmount"> B B B B B B B <xsl:for-each select="highlight"> B B B B B B B B B B B <xsl:sort select="if (normalize-space() castable as xs:decimal) then descending B B B B B B B B B B B B B B B else ()"/> B B B B B B B </xsl:for-each> B B B </xsl:param>
B B B <xsl:template match="result"> B B B B B B B <xsl:variable name="doc" select="document(@uri)"/> B B B B B B B <xsl:element name="Trade"> B B B B B B B B B B B <xsl:for-each-group select="." group-by="@uri">
A select="." on for-each-group is an attempt to group a single element and if the group-by="@uri" selects a single grouping key value I fail to understand what that whole attempt is about.
Question Two: Below produces the same result by replacing Line 55 - 60 in my original XSLT module. Can someone point out if below module is syntactically correct? (It runs fine in the Oxygen.)
B B B B B B B <xsl:for-each-group select="." group-by="@uri">
Same here, a single element grouped by its single @uri attribute value simply processes that single element. Grouping doesn't make sense on a single element with a single grouping key, in my understanding.
