        <custom-attribute attribute-id="sscAccountid">0011x000014VegoAAC</custom-attribute>

Custom-attribute looks like standard tag. Wrap it to the quotes and it will work fine. custom-attribute is an array which is indicated by asterisk in the DW transformation. From this array (line 19 creates it) we filter all items with attribute (indicated by @ character) equal sscAccountId.

Result is array with one element.

        <custom-attribute attribute-id="sscAccountid">0011x000014VegoAAC</custom-attribute>
    </custom-attributes>
</order>','application/xml')
output application/json

(payload.order."custom-attributes".*"custom-attribute") 
 filter (item) -> (item.@"attribute-id" ~= "sscAccountid")
