how to rename multiple reader feature type attributes with different names to a single writer feature type attribute
+5- Contributor
I have multiple FCs in multiple FGDBs which I need to run through NeighbourFinder to generate distance/proximity info and then write into a single Excel writer feature type. These FCs have certain attributes I want to carry over into the writer but they are all named slightly differently. I would like some suggestions on the best way to carry this out please so it is easy to swap different combinations of Attribute in and out.

Hi,
I cannot grasp your requirement exactly yet, but try "super-clairvoyance" ;)
If each of "SSSI_NAME", "Location", "Name", "TYPE" and "LNR_NAME" is from different feature type and you are trying to replace all of them with an identical name, this could be a solution.

Hi,
have a look at the BulkAttributeRenamer. If that isn't enough, the SchemaMapper might be the next step (more powerful, but also a lot more complex to configure).

Thanks. I have had a look at the BulkAttributeRenamer but can't seem to get it to work. I have tried RegEx and String replacer but I am not getting the desired reuslt. Is it best to rename everyting to a 'new' name or match to an existing one?

All of the attributes in above AttributeKeeper come from different FCs but hold the same type of attribute. i would like to be able to write these to a single Excel writer as a single attribute, possibly NewName, and have an attribute that contains the name of the source feature type.
If I suppose only one of these attributes hold a value for any given feature, you could use a few chained NullAttributeMappers to isolate the one attribute holding a value, then rename it using a regular AttributeRenamer.

That's it! I think I had just been incorrect with the sytax I was using for the RegEx. This now does what I what it too. In this example I provided a subset of attributes to handle, but I think I will be able to now use this technique on other combinations, such as each FC has a different attribute for their Unquie IDs which I would want to handle in this way also. There are a few other groups of Attribute which need to consolidated in this way so I guess a BulkAttributeRenamer for each insatnce.
