Given the following XML which is out of my control:
<Stuff>
<SomeData>
<SomeDataStuff>
<AccountDetails>
<Person xsi:nil="true" />
<Person xsi:nil="true" />
</AccountDetails>
<CandidateDetails>
<Candidate xsi:nil="true" />
<Candidate xsi:nil="true" />
</CandidateDetails>
</SomeDataStuff>
</SomeData>
</Stuff>
I am able to unmarshal using the following, can it be simplified somewhat?
type Stuff struct {
XMLName xml.Name
SomeData SomeData
}
type SomeData struct {
XMLName xml.Name
SomeDataStuff SomeDataStuff
}
type SomeDataStuff struct {
AccountDetails AccountDetails `xml:"AccountDetails"`
CandidateDetails CandidateDetails `xml:"CandidateDetails"`
}
type AccountDetails struct {
Person []Person
}
type CandidateDetails struct {
Candidate []Candidate
}
type Person struct {
...
}
type Candidate struct {
...
}
Im not worried about marshalling, just unmarshalling. Really all I need is an array of Person
and Candidate
, not a whole sequence of nested pointless struct's
You can use a selector, for example:
// replace []string with []Person/[]Candidate
type Stuff struct {
People []string `xml:"SomeData>SomeDataStuff>AccountDetails>Person"`
Candidates []string `xml:"SomeData>SomeDataStuff>CandidateDetails>Candidate"`
}
//edit, I updated the example to show that marshalling also works fine.
From http://golang.org/pkg/encoding/xml/#Unmarshal :
* If the XML element contains a sub-element whose name matches
the prefix of a tag formatted as "a" or "a>b>c", unmarshal
will descend into the XML structure looking for elements with the
given names, and will map the innermost elements to that struct
field. A tag starting with ">" is equivalent to one starting
with the field name followed by ">".
