I want to create desktop apps

Hi I'm trying to create a desktop app where I can visualise data inside an XML file. The XML file can be huge and deeply nested and some tags can be only meta data not anything visual. I'm using Go for backend and react as frontend with wails.io for creating desktop. I found creating structs for large XML files cumbersome and hard to parse when made it into json in the frontend. I also tried loading the XML as itself and converting into node tree but it takes a lot of load time. I'm required to use this XML and it's structuring to represent data. Please suggest some approaches. Thanks in advance
