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.

Nil pointer dereference #27

Closed coussej closed 7 years ago

coussej commented 7 years ago

Hi, first of all thanks for this package!

I'm trying to generate go structs from the file AllSchemas.xsd. I use the following command...

xsd-makepkg -local=true -uri="AllSchemas.xsd" -basepath="github.com/coussej/b2mml"

... which results in a nil pointer dereference error:

2017/04/18 11:59:14 LOAD:   AllSchemas.xsd
panic: runtime error: invalid memory address or nil pointer dereference

I also tried serving the files over a local server, but this results in the exact same error!

The complete schema can be found attached: b2mml.zip

Any ideas?

Try the various forks of go-xsd that appeared over the years: https://github.com/metaleap/go-xsd/network --- I'm not maintaining/supporting/pondering this package at all nowadays =)
