Hi all,

I have a question regarding string searching, which is slighlty related to a vlookup process.

I have two datasets.

One is a shapefile of a pipe network that has a concatenated output from civil design package. The field is named 'Partsizename' and contains values like "305 mm Concrete Pipe" or "151 NB UPVC PN". The other is an excel spreadsheet containing a field named 'Material', which lists 40 common pipe materials (e.g. "Concrete", "UPVC", "Copper").

I want to search Partsizename for the values listed in Material, and if any match, output the matching string into another field. E.g. For a row in Partsizename that contains "305 mm Concrete Pipe", 'Concrete' is one of the materials listed in 'Material', so the output will be 'Concrete'.

Thanks in advance for any help!

Does the data in the excel spreadsheet change or is it fixed?

If fixed you can probably use the detail to write a regular expression to return the value you are interested in from the Partsizename attribute and store in a new attribute

I would use an inlineQuerier with the SQL statement:

 

SELECT *
FROM Pipes
LEFT JOIN Materials
ON INSTR(Pipes.Partsizename, Materials.Material) > 0

 

 

Two input ports, one connected to the pipe shapefiels (Pipes), the other to the Material excel file (Materials)

Hi @jordan_miller,

I created a template Workflow and simulated with polygon.

You can see below the two Readers and create a commun attribute between two readers ( Transformer AttributeCreator ).

In the end i generate the shape file with a new attribute Result.

Thanks,

@danilo_inovacao you don't need to create an attribute for the FeatureMerger, you can just set the requestor and supplier to the same hardcoded value, ex. 1.

Hi @egomm, good question; I initially searched for regular expressions which works well, but the spreadsheet has the potential to change, hence why I was interested in searching the entire materials field. Thanks for your response

Hi @jdh, thanks for your response! That makes sense, will give it a go

Hi @danilo_inovacao, thanks for taking the time to post your workflow. Will have a look at it

If the spreadsheet can change, you can aggregate all attributes to create a regular expression merge it with the other features and then use a string searcher to set the new attribute
