metaleap / go-xsd

[stable since 2013] a lib for loading XML Schema Definition (XSD) files ➜ plus, a tool `makepkg` to code-generate from any *.xsd your Go package with all needed `struct`s to readily `xml.Unmarshal()` documents into, based on the XSD's schema definitions. NOT REALLY MAINTAINED FOR YEARS NOW: try the forks if running into issues.

@metaleap I'm having the same issue with a Juniper JUNOS XSD file (I have to serve it from a localhost since it's not on a public URI)
