Hi Heiko (or Hi Ko, as we say here b sorry, I should avoid lame jokes
about names b OTOH, this rule is not written in the posting guidelines,
Tommie!),
That being said, I must admit that I somehow managed to ignore your preceding post when I posted my solution this afternoon. My solution suffered from the same shortcoming as yours. I now inserted a new second pass that will insert more ranges if need be. It feels clumsier and clumsier, but it covers all test cases known so farb& Input: <ranges> <range start="100" end="300" /> <range start="150" end="190" /> <range start="200" end="280" /> </ranges> XSLT: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0"> <xsl:output indent="yes"/> <xsl:template match="/ranges"> <xsl:variable name="pass1" as="element(pass1)"> <pass1> <!-- eliminates duplicate start/end attributes and creates a new range for each distinct start and end value: --> <xsl:for-each-group select="range/(@start|@end)" group-by="string-join((name(), .), '=')"> <xsl:sort select="." data-type="number"/> <range> <xsl:sequence select="."/> <!-- adds a start attribute to the end attribute iff the start attribute's value is smaller than the end attribute's: --> <xsl:sequence select="../@start[. < current()]"/> </range> </xsl:for-each-group> </pass1> </xsl:variable> <xsl:variable name="pass2" as="element(pass2)"> <pass2> <!-- Fill gaps with new ranges (Heikobs test case) --> <xsl:apply-templates select="$pass1/range" mode="pass2"/> </pass2> </xsl:variable> <xsl:variable name="pass3" as="element(pass3)"> <pass3> <!-- Replaces the existing start attribute with the nearest value available, looking behind (template with xml:id="B" below).
