Have you tried using the ListExpressionPopulator

You could use a regular expression ^[CIS|TPS] for the right attributes.

Hope this helps.

I tried with the regexp ^CIS|^TPS (which doesn't produce the same result as your regexp strangely...).

But the result is not as expected, I have a list with the 6 values like this :

 

 

And how about using the AttributeManager, renaming CIS1 to List{0}.CIS , TPS1 to List{0}.TPS and so on.

This only works if the source attributes are always the same.

Hi @p.jeremie, 

I have two ideas:

BulkAttributeRenamer with Regular Expression Replace mode

 

JSONTemplater and JSONFlattener

Template Expression

{
    "List" : >
        let $c := fme:get-list-attribute('CIS{}')
        let $t := fme:get-list-attribute('TPS{}')
        for $i in (1 to count($c))
        return
        {
            "CIS" : $cÂ$i],
            "TPS" : $t $i]
        }
    ]
}

How is the information on what figures are needed to be added for each letter combination stored, and how many are there?

{
    "List" : >
        let $c := fme:get-list-attribute('CIS{}')
        let $t := fme:get-list-attribute('TPS{}')
        for $i in (1 to count($c))
        return
        {
            "CIS" : $cÂ$i],
            "TPS" : $t $i]
        }
    ]
}

@takashi I like your BulkAttributeRenamer solution ! In the meantime I used the ListZipper transformer to achieve my goal but I prefer this solution. Thanks a lot.

@egomm The delay to be add are in a xlsx file with the key CIS and value in a Delay column.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

For the moment my solution is to explode the list I created and perform a FeatureJoiner on the CIS key. This way I can create a new attribute TPSnew = @Evaluate(@Value(TPS)+@Value(DELAY))

I still have to sort and re-create my CIS1, CIS2... columns.

I'd probably use a python caller to create a list.

But if you're using python anyway, I'd try and do the addition as well, to avoid having to explode and recombine

 

import fme
import fmeobjects

def processFeature(feature):
    lookup = {'AMA':1000,'CHL':700,'LOR':1500,'LIV':1000,'RBN':300}
    tpslist = F]
    for i in range(1,4):
        cis = feature.getAttribute('CIS'+str(i))
        tps = feature.getAttribute('TPS'+str(i))
        newtps = tps + float(lookup.get(cis))
        tpslist.append((i,newtps))
        
        feature.setAttribute('NewTPS'+str(i),newtps)
    
    lowest =  (min(tpslist, key = lambda t: tÂ1]))
    feature.setAttribute('lowest','TPS'+str(lowest 0]))

 

Which would give you this sort of output

import fme
import fmeobjects

def processFeature(feature):
    lookup = {'AMA':1000,'CHL':700,'LOR':1500,'LIV':1000,'RBN':300}
    tpslist = I]
    for i in range(1,4):
        cis = feature.getAttribute('CIS'+str(i))
        tps = feature.getAttribute('TPS'+str(i))
        newtps = tps + float(lookup.get(cis))
        tpslist.append((i,newtps))
        
        feature.setAttribute('NewTPS'+str(i),newtps)
    
    lowest =  (min(tpslist, key = lambda t: t 1]))
    feature.setAttribute('lowest','TPS'+str(lowest<0]))

@egomm Thank you for your proposal.

Can you explain me the part below ?

lowest =  (min(tpslist, key = lambda t: t<1]))    feature.setAttribute('lowest','TPS'+str(lowesty0]))

And how can I use my Excel data of the "Delay table" in the PythonCaller ? I saw you put them in a lookup dictionary but I don't know how to recreate it...

 

In fact, to simplify I said I need to get the quicker TPS, but in reality I need to sort all my CISx with their new time.

So I need to have this result :

Start Table

 

Delay table

 

 

 

 

 

 

 

 

 

 

 

 

 

New Table (underlined CIS have change place with the time sort)

 

 

 

 

I assume it can be quicker/more efficient to to all this in python but I don't know how to do it as I'm not used to code python.

And I'm wondering if this kind of processing is stable on a long term (new versions of python). Is it not better to used fme transformer to ensure that my workspace will continue to work well ? i would appreciate any advice on this subject.

Good idea, I didn't know it was possible to do so.

But I prefer the takashi solution. Thanks anyway !

lowest =  (min(tpslist, key = lambda t: te1]))    feature.setAttribute('lowest','TPS'+str(lowestl0]))

I generally work on the idea that if something can be done in fme in less than 5 transformers, I'd choose that over a python solution (with some exceptions for certain things where python is just much faster). 

 

What you are trying to achieve is to me much more straightforward to do in python than in FME (and i only dabble in python in FME, i'm not an expert)

 

The last bit of the python is finding the minimum value of your new TPS values, and writing that to a new attribute. If you actually want the CIS2 to become CIS1 and TPS2 to become TPS1 based on values you need a slightly different process

I've attached a template file that will create your NewTable

import fme
import fmeobjects

def processFeature(feature):
    #dictionary of lookup values
    lookup = {'AMA':1000,'CHL':700,'LOR':1500,'LIV':1000,'RBN':300}
    
    #create list
    tpslist = p]
    for i in range(1,4):
        cis = feature.getAttribute('CIS'+str(i))
        tps = feature.getAttribute('TPS'+str(i))
        #add delay to tps based on cis value
        newtps = tps + float(lookup.get(cis))
        #add values to list
        tpslist.append((cis,newtps))
    #sort list in ascending order by second item in tuple
    tpslist.sort(key=lambda tup: tupp1])
    #step through ordered list and create new attributes named in same order as list
    for i,(cis,newtps) in enumerate(tpslist):
        feature.setAttribute('CIS'+str(i+1),cis)
        feature.setAttribute('NewTPS'+str(i+1),newtps)

@p.jeremie updated template with lookup from excel

import fme
import fmeobjects

def processFeature(feature):
    #dictionary of lookup values
    lookup = {'AMA':1000,'CHL':700,'LOR':1500,'LIV':1000,'RBN':300}
    
    #create list
    tpslist =  ]
    for i in range(1,4):
        cis = feature.getAttribute('CIS'+str(i))
        tps = feature.getAttribute('TPS'+str(i))
        #add delay to tps based on cis value
        newtps = tps + float(lookup.get(cis))
        #add values to list
        tpslist.append((cis,newtps))
    #sort list in ascending order by second item in tuple
    tpslist.sort(key=lambda tup: tupn1])
    #step through ordered list and create new attributes named in same order as list
    for i,(cis,newtps) in enumerate(tpslist):
        feature.setAttribute('CIS'+str(i+1),cis)
        feature.setAttribute('NewTPS'+str(i+1),newtps)

Great !

Now I need to find how can I use my Excel data of the "Delay table" in the PythonCaller. I saw you put them in a lookup dictionary but I don't know how to recreate it... 

Does the lookup table change?

Yes it can change (keys and delays)... That's why I can't write it raw in the PythonCaller.

I've updated the template with an example of how you could do this - it's probably not the most efficient but it works
