[go-nuts] Re: dynamic xml
You'll need to use an UnmarshalXML func for the params:
// Param is a tag w/ any name
type Param struct {
Namestring `xml:"-"`
Typestring `xml:"type,attr"`
MinOccurs int`xml:"minOccurs,attr"`
MaxOccurs int`xml:"maxOccurs,attr"`
Description string `xml:"description"`
}
// ParamList type for unmarhsal
type ParamList []Param
// UnmarshalXML for the win
func (pl *ParamList) UnmarshalXML(d *xml.Decoder, s xml.StartElement) error
{
tk, err := d.Token()
for err == nil {
switch t := tk.(type) {
case xml.StartElement:
param := Param{Name: t.Name.Local}
if err = d.DecodeElement(, ); err != nil {
return err
}
*pl = append(*pl, param)
}
if tk, err = d.Token(); err == io.EOF {
return nil
}
}
return err
}
// TopLevel is of course top level
type TopLevel struct {
Description string `xml:"description"`
Rights Rights `xml:"rights"`
Method []Method `xml:"method"`
}
// Method has request
type Method struct {
Namestring `xml:"name,attr"`
Description string `xml:"description"`
Rights []Right `xml:"rights"`
Request Request `xml:"request"`
ResponseResponse `xml:"response"`
}
// Right whatever
type Right struct {
Right string `xml:"right"`
}
// Request like Response
type Request struct {
Params ParamList `xml:"params"`
}
// Response like Request
type Response struct {
Params ParamList `xml:"params"`
}
// Rights
type Rights struct {
PrivLevel string `xml:"privLevel"`
}

[go-nuts] Re: dynamic xml
You'll need to use a custom UnmarshalXML func to handle this.
// TopLevel is of course top level
type TopLevel struct {
Description string `xml:"description"`
Rights Rights `xml:"rights"`
Method []Method `xml:"method"`
}
// Method has request
type Method struct {
Namestring `xml:"name,attr"`
Description string `xml:"description"`
Rights []Right `xml:"rights"`
Request Request `xml:"request"`
ResponseResponse `xml:"response"`
}
// Right whatever
type Right struct {
Right string `xml:"right"`
}
// Request like Response
type Request struct {
Params ParamList `xml:"params"`
}
// Response like Request
type Response struct {
Params ParamList `xml:"params"`
}
// ParamList type for unmarhsal
type ParamList []Param
// UnmarshalXML for the win
func (pl *ParamList) UnmarshalXML(d *xml.Decoder, s xml.StartElement) error
{
tk, err := d.Token()
for err == nil {
switch t := tk.(type) {
case xml.StartElement:
var param = Param{Name: t.Name.Local}
if err = d.DecodeElement(, ); err != nil {
return err
}
*pl = append(*pl, param)
}
tk, err = d.Token()
}
return err
}
// Param holds data
type Param struct {
Namestring `xml:"name"`
Typestring `xml:"type,attr"`
MinOccurs int`xml:"minOccurs,attr"`
MaxOccurs int`xml:"maxOccurs,attr"`
Description string `xml:"description"`
}
// Rights hmm
type Rights struct {
PrivLevel string `xml:"privLevel"`
}
