Others have pointed out that value-of will produce an epty text node from a empty element, but most likely you don't want to this at all. > I think it has something to do with the type of the > variable, because it is not initialised as a result-tree fragment. > Has anyone come across this problem before? By the way, I am using > Saxon-B 9.1.0.3. There are no result tree fragments in xslt 2 thankfully that has gone. <xsl:variable name="mappingsCodeA"> If you use value-of inside xsl:variable in thsi way you are not assigning a string or attribute node to the variable but a document node with child text node with string value the string value of the selection which is relatively expensive to build and to use. You were testing for count=1 but im guessing that you just mean to use map:entry[@codeA=$valueOfCodeA] if it exists or map:otherwise otherwise <xsl:variable name="mappingsCodeA" select="$lookupTable/map:table/ (map:entry[@codeA=$valueOfCodeA],/map:otherwise)[1]"/> Then you can use $mappingsCodeA/@codeB as because you have used a selct attribute $mappings references the node in your lookup table, not a document node containing a newly constructed tree.
