XMLFragmenter

Hi all,

 

 

I am using XMLFragmenter. I am giving "bldg:Building/bldg:lod2Solid" as element to match.

 

So the result I am looking is, to know which surfaces are given as href for each building. (shown here)

 

 

 

Actually, I need to check if all the surfaces that I have are given as xlink or not. Therefore, I need to expose all the "Solid.exterior.CompositeSurface.surfaceMember{}.href". But because they behaving as list attribute and also they are not stored as list in this transformer I do not know how to expose them (because the list numbers are dynamical and them might vary from 4 to n for different buildings).

 

 

I am looking forward to hearing from you.

 

 

Thank you in advance,

 

Mani

Hi Mani,

 

 

I can see a list attribute named "Solid.exterior.CompositeSurface.surfaceMember{}" in your posted image. The list has been certainly created.

 

But you cannot manipulate it with transformers if you have not expose the name.

 

Try exposing the name with the "Attributes to Expose" parameter.

 

 

 

Just be careful not to make a typo.

Hi,

 

 

there are several transformers available for manipulating variable length lists. Some that might be relevant to you: ListExploder, ListElementCounter, ListIndexer.

Hi David,

 

 

Thank you for your reply.

 

I think the mentioned transformers do not work here because XMLFragmenter does not produce any list attribute (as far as I know).

That is exactly my problem.

Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

Hi Takashi,

 

 

I didn't know that first I need to expose it. Thank you so much.
