Issues with xsd2ttcn [message #1791539]

Dear Elemer,

I got some issues trying to generate TTCN-3 files from XSD files (see attached xsd.tar.bz2 file), using xsd2ttcn tool.
When generating TTCN-3 files, it seems that some imports were missing.
I tried to add them manually, but I got TTCN-3 compiler errors at the end.

May I ask you your help to fix it, please?

Many thanks in advance,

Yann

Hi Yann,

indeed , when I run xsd2ttcn over your files, results in:

xsd2ttcn *.xsd

Notify: No errors and 4 warnings were detected.

Note though that only warnings are issued and the *.ttcn files are generated.

Now if we look into the warning:

RFC3863_pidf.xsd (in line 10): Element '{http://www.w3.org/2001/XMLSchema}import': Failed to locate a schema at location 'http://www.w3.org/2001/xml.xsd'. Skipping the import.

this only means that the converter cannot follow links or hyperlinks, all XSD's have to be present and located in the same directory. Import links and hyperlinks will have to be replaced with a direct local reference.

In this case , all

	 <xs:import namespace="http://www.w3.org/XML/1998/namespace"
     schemaLocation="http://www.w3.org/2001/xml.xsd"/>

are to be replaced with:

	 <xs:import namespace="http://www.w3.org/XML/1998/namespace"
     schemaLocation="xml_2001.xsd"/>

With this done,
one warning remains:

RFC3863_pidf.xsd (in type Qvalue): Pattern restriction is not supported on type 'decimal'.

which is kinda self-explanatory.

Commenting out the offending code:

<xs:simpleType name="qvalue">
  <xs:restriction base="xs:decimal">
    <!-- xs:pattern value="0(.[0-9]{0,3})?"/>
    <xs:pattern value="1(.0{0,3})?"/ !-->
  </xs:restriction>
</xs:simpleType>

will get rid of this warning too.

See attached archive.

Best regards
Elemer

Hello Elemer,

Houla, I missed the issue with the pattern, For XSD, I agree, it was provided by the LibSip.
Unfortunately, some imports seems to be missing: I got this error:
../ttcn/http_www_opengis_net_gml.ttcn:900.2-10: error: There is no local or imported definition with name `Ellipsoid'

Thanks a lot.

Hi Yann,

the definition of Ellipsoid is there, both in .xsd and .ttcn:

grep llipsoid *.xsd
GML-pidf-lo-shape.xsd:    <xs:element name="Ellipsoid" type="gs:EllipsoidType"
GML-pidf-lo-shape.xsd:    <xs:complexType name="EllipsoidType">
esekilxxen1845 [15:23] [YannGarcia/XSD@TTCN/xsd] ->
esekilxxen1845 [15:23] [YannGarcia/XSD@TTCN/xsd] ->
esekilxxen1845 [15:23] [YannGarcia/XSD@TTCN/xsd] -> grep llipsoid *.ttcn
http_www_opengis_net_gml.ttcn:  Ellipsoid ellipsoid,
http_www_opengis_net_gml.ttcn:  variant (ellipsoid) "name as capitalized";
http_www_opengis_net_pidflo_1_0.ttcn:type EllipsoidType Ellipsoid
http_www_opengis_net_pidflo_1_0.ttcn:type record EllipsoidType

but it's not imported:

module http_www_opengis_net_gml {


import from XSD all;
:

:

try to add "import from http_www_opengis_net_pidflo_1_0.ttcn all"

to http_www_opengis_net_gml.ttcn

Hello Elemer,

Yes, I did it, but in this case, I got a cyclic import between http_www_opengis_net_gml.ttcn and http_www_opengis_net_pidflo_1_0.ttcn.
When the C++ code is generated, I got errors while compiling http_www_opengis_net_gml.cc beacause of http_www_opengis_net_pidflo_1_0.hh not included in http_www_opengis_net_gml.hh

I attached the generated files. The file out.txt is the output of the make (make > out.txt 2>&1).

Thanks again for your help,

Yann

Hi Yann, you're right ,

there's a glitch, we are looking into it.

Some structures are generated into http_www_opengis_net_gml.ttcn

instead of http_www_opengis_net_pidflo_1_0.ttcn

I have moved them to their right place and then it compiles ( see attached)

I'll come back to you.

Hi Yann,

ok , here's the update on this issue:

the problem is that in such cases the converter generates definitions in the wrong file.
As a countermeasure we have introduced a switch -o which will have to effect to force generation of single TTCN file with a set name XSD_Definitions.ttcn , not one file per namespace
as without the -o switch.

Namespaces are separated in groups though.

 xsd2ttcn -o *.xsd

Hi Yann,

in fact if this option is used in a smart way, the advantage of generating one file per namespace can be retained:

If you look at the import/include dependencies you can see that your package contains two sets of files that are unconnected so we can convert them in two steps:

xsd2ttcn -o basicTypes.xsd gmlBase.xsd measures.xsd geometryBasic0d1d.xsd geometryBasic2d.xsd geometryPrimitives.xsd GML-pidf-lo-shape.xsd
