Feature contains elements from two lists

Hi @jdh,

You can use a combination of ListConcatenator and AttributeCreator to concatenate the _option lists into regex expressions (ie. [XYZ]). Then use two StringSearchers to search _list by those expressions. I am attaching a workspace to illustrate.

searchlist.fmw

Create two attributes in python that are populated depending on whether there is a match between each list, then you can test for where match_list1 or match_list2 are both true.

import fme
import fmeobjects

def processFeature(feature):
    match1 = ['A','B','C']
    match2 = ['X','Y','Z']
    list = feature.getAttribute('_list{}')

    for x in list:
        if any(y in x for y in match1):
            feature.setAttribute('match_list1','true')
        if any (y in x for y in match2):
            feature.setAttribute('match_list2','true')
        

Unfortunately the actual codes are not single characters, so I end up with many false positives.

import fme
import fmeobjects

def processFeature(feature):
    match1 = ['A','B','C']
    match2 = ['X','Y','Z']
    list = feature.getAttribute('_list{}')

    for x in list:
        if any(y in x for y in match1):
            feature.setAttribute('match_list1','true')
        if any (y in x for y in match2):
            feature.setAttribute('match_list2','true')
        

I had tried the 'any'  but got lost in triple for loops,  running two separate searches and testing for True and True  is the piece I was missing.
