This is my first time posting here, so I apologize in advance for the length and for any format issue or lack of information. I've been working on this problem for a few days and I've researched my problem extensively but haven't found a solution yet, so I am hoping someone here can help me. It's an xslt related issue and I only started coding in xslt a couple of months ago so I'm not so experienced.
Basically, I have an input XML which may contain duplicate records as well as empty tags and I need to reorganize them into a javascript associative array to be able to manipulate and display the values efficiently on the client side.
My question is: Is there a way to do a multilevel grouping even if the used field tag is empty. If not, is there a way I can edit the xml in xsl by replacing the empty tag with a keyword and then applying the rest of my templates?
To understand my problem here are the details. This is my input XML

I looked online and found that the best way to deal with multilevel grouping is to use xsl:key and generate-id(). That worked great and the data came out exactly as I wanted to, so the flow of my xsl is correct. But unfortunately if the field used in the xsl:key is an empty tag, when I go into the multilevel grouping using concat(), it fails.

As you can see, in the Race->Unknown section, it doesn't complete it by applying the template mode "buildAnalyticsTableCountLevel" so I never get the ORGUNITID information which is very important in what I am doing.
I unfortunately cannot edit the xml coming in as this is a part of a much bigger framework used in various projects and I cannot change it. So I have to work with what I get.
I tried using the string() method in xsl:key but that makes everything worse. Any tips or help is appreciated. Thanks in advance!
