Validate XRechnung

[jstaerk]

since the xrechnung xsl files are available in their configuration https://github.com/itplr-kosit/validator-configuration-xrechnung/releases one could check if they could be added e.g. on a warning or notice level

[jstaerk]

actually it's more https://github.com/itplr-kosit/xrechnung-schematron/releases which should be added, some derivative of /schematron/cii/XRechnung-CII-validation.sch .

factur-x.txt is a sample file which correctly fills the report.xml with the message that the seller contact is missing with something like

java -jar saxon9he.jar -o:report.xml -s:factur-x.txt XRechnung-CII-validation.xsl

in ZUV's XMLValidator.java around line 263 there is the additional check for the CEN schematron for Generation 2 (=ZF2 or FX1) files with EN16931 profile, that something like

    validateSchematron(zfXML, "/xslt/XRechnung-CII-validation.xsl", 27);

could be added there after copying the XSLT to src/main/resources/xslt. This would introduce an error type 27 for xrechnung issues. My issue is that this currently causes a nullpointerexception, I assume because XRechnung-CII-validation.xsl is XSLT2: So far I could not convert it to XSLT1, neither could I get ph-schematron to process any XSLT2 files.

and the xslt being generated using java -jar saxon9he.jar -o:/xr.xsl -s:./schematron/cii/XRechnung-CII-validation.sch ./stf-master/iso-schematron-xslt2/iso_svrl_for_xslt2.xsl I get a couple of Error: unrecognized element in ISO Schematron namespace: check spelling and capitalizationparam but a XSLT file which then nullpointerexcepts, when I use the transformation to xslt1 java -jar saxon9he.jar -o:/xr.xsl -s:./schematron/cii/XRechnung-CII-validation.sch ./stf-master/iso-schematron-xslt1/iso_svrl_for_xslt1.xsl I get even more severe errors and no XSLT output at all

[jstaerk]

some updates from https://github.com/phax/ph-schematron/blob/master/ph-schematron/src/test/java/com/helger/schematron/supplementary/Issue16Test.java : pom.xml, java and XSLT files in the project phtest2.zip

[jstaerk]

after a manual attempt Philip Helger has converted the schematron with his maven tasks, which unfortunately does not work when I try it. Nevertheless, I switched back to ph-schematron and I'm now using his xsl from https://github.com/phax/ph-bdve/tree/master/ph-bdve-xrechnung/src/main/resources/schematron/1.2.2 for the time being

[jstaerk]

should now works for XR 1.2.2 and XR 2.0 in mustang 2 alpha https://mustangproject.org
