Go create struct from XML

Question

Please see this playground: https://play.golang.org/p/FOMWqhjdneg As you can see I have a XML response which I want to unmarshal into a Product struct. The XML has an "assetBlock" which contains nested nodes and extract data to Product struct. Any help would be appreciated

What do you want to parse from the XML? Do you need to model the complete XML document? — icza

You need to make a struct for AssetBlock and all of the types below it, I've done it up to group to show you what I mean:

https://play.golang.org/p/vj_CkneHuLd

type Product struct {
    GlobalID   string     `xml:"globalId"`
    Title      string     `xml:"title"`
    ChunkID    int        `xml:"gpcChunkId"`
    AssetBlock assetBlock `xml:"assetBlock"`
}
type assetBlock struct {
    Images images `xml:"images"`
}
type images struct {
    GroupList groupList `xml:"groupList"`
}
type groupList struct {
    Groups []group `xml:"group"`
}
type group struct {
    Usage string `xml:"usage"`
    Size string `xml:"size"`
}

Thanks! Really helpful. However, I tried to enter the asset-part, but for some reason I can't figure out how to get the urls. See this playfround: play.golang.org/p/t6X2xbQ1PNT

You need to capitalize the property names: play.golang.org/p/AUnvdlkgq2E any lower case first letter is private in go and will be ignore by the XML encoders.

That's it! Damn... thanks, everything works fine now.
