using Saxon 6.5.5. in a windows command line using this command:

java -jar C:\Saxon\Saxon6.5.5\saxon.jar -t -o calimero.xml 0.xml ets4_calimero_gui.xsl

The two files are in the correct directory and the output is the followed:

'SAXON 6.5.5 from Michael Kay
 Java version 1.6.0_31
 Loading com.icl.saxon.sort.Compare_d
 Preparation time: 225 milliseconds
 Processing file:/C:/Saxon/Saxon6.5.5
 Building tree for file:/C:/Saxon/Sax
 tree.TinyBuilder
 Tree built in 33 milliseconds
 Loading java.net.URI
 Execution time: 100 milliseconds'

But the created calimero.xml only includes the following line:

<?xml version="1.0" encoding="iso-8859-1"?>

Does anybody know the problem?

Thanks, Mike

Answer 1

It's not related to your problem, though it is related to the fact that you seem to be fairly inexperienced in XSLT...

Firstly, if you are using Saxon then there really can't be any good reason for using XSLT 1.0. (Even less, "XSLT 1.1" which was an abandoned working draft that was never finished). You should move to a recent Saxon release (the current version is 9.4) and take advantage of all the benefits of using XSLT 2.0.

Secondly, even given the limitations of XSLT 1.0, this is really bad code:

(a) It's written completely monolithically - one template rule only

(b) it uses the preceding axis, which is very inefficient

(c) it uses xsl:attribute unnecessarily, which is very verbose

etc.

To give you a feel for the difference, the datapoint element and its attributes could be created like this (some of the improvements, but not all, depend on XSLT 2.0):

<datapoint 
    stateBased="true" 
    name="{$verz/@Name}"
    mainNumber="{if (../@DatapointType != '')
                 then if(string-length(../@DatapointType) gt 5)
                      then $master2/../../@Number
                      else $master3/@Number
                 else $master/@Number}"
    dptId="{if (../@DatapointType != '')
            then if (string-length(../@DatapointType) gt 5)
                 then concat($master2/../../@Number, '.',format-number($master2/@Number, '000')
                 else concat($master3/@Number, '.001')
            else concat($master/@Number,'.',format-number($master/b:DatapointSubtypes/b:DatapointSubtype/@Number, '000'))}"
    priority="{(../@Priority, $verz/@Priority)[1]}"

That's 51 lines of code down to 14, and it could come down further by moving the common code fragments into a function.

Answer 2

Your XML input is in the xmlns:

xmlns="http://knx.org/xml/project/11"

Whereas your xslt is looking for

xmlns:b="http://knx.org/xml/project/10"

Looks like the schema version has been bumped up :)
