I have an xml that looks like this:
<MyElement>
<Ids>
<int>1</int>
<int>2</int>
</Ids>
</MyElement>
I find it challenging to parse in go. I've tried the following
type MyElement struct {
Ids int[]
}
or even
type Ids struct {
id int[] `xml:"int"`
}
type MyElement struct {
Ids Ids
}
But it never get picked up.
The difficulty is in the fact that the elements are all called int and only store an int value, instead of the usual key/value pair.
You need to specify the path the int elements:
type MyElement struct {
Ids []int `xml:"Ids>int"`
}

You can also do this in order not to repeat "Ids"
type MyElement struct {
Ids []int `xml:">int"`
}
This functionality is mentioned in xml.Unmarshal's documentation:
- 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 ">".
