IDS Specification: Only specific parameters must be presented within a Pset

SimoneM

Hi, for some time I've been developing automatisms in Python that create specific rules for me through ids files to be subsequently validated in Solibri. Doing some tests I was unable to make a specification work: I want only a list of parameters to be allowed within a specific pset, if there is one that is not allowed it must return the error.
until now I have set the specification like this via restriction in Regex, what am I doing wrong?

in the case shown in the image, even if a parameter named param_04 appears in that specific pset it does not return the error.

I might be wrong but maybe you should try something like this:

       <xs:restriction base="xs:string">
          <xs:enumeration value="Param01" />
          <xs:enumeration value="Param02" />
          <xs:enumeration value="Param03" />
        </xs:restriction>

I cannot try to check 'cause i've issues with blender IfcTester maybe due to my experiments with files.
Hope it helps

tried but it doesn't work, maybe because the requirement is satisfied for the other parameters present that are contained in the list.
thats how i created in python the series of enumerations in a loop:

the result:

I tried inserting parameters that were not in that list in the specified pset and I don't get the error with ids checker of Solibri :(

Unfortunately that regex is likely not allowed in XML :( XML's regex patterns are pretty simple and lack these kind of negative lookahead patterns.

There's a really ugly hack you can do: [ALPQV][laueo][trnsol][egotu][zham]?[ze ]?... and so on. I feel dirty for even suggesting it :)

Got It , I'll settle for trying to control the number of parameters inside the pset, and check in another specification that there is the single parameter in that pset
