Complex XML Response

[DanielZambranoC]

Hi, I've been trying to parse an answer and I still can't get it right.

I have tried in different ways, which I believe closer has been the structure provided by this tool (https://www.onlinetool.io/xmltogo/)

I need to be able to extract indexDateString and value

Can you advise me on where I am failing?

Error obtained: xml.Unmarshal error: EOF

Try 1

type GetSeriesResponse struct {
    XMLName         xml.Name `xml:"GetSeriesResponse"`
    Text            string   `xml:",chardata"`
    Xmlns           string   `xml:"xmlns,attr"`
    GetSeriesResult struct {
        Text   string `xml:",chardata"`
        Series struct {
            Text       string `xml:",chardata"`
            FameSeries struct {
                Text string `xml:",chardata"`
                Obs  []struct {
                    Text            string `xml:",chardata"`
                    Xmlns           string `xml:"xmlns,attr"`

                    StatusCode      string `xml:"statusCode"`
                    Value           string `xml:"value"`

@DanielZambranoC

type Obs struct {
    XMLName         xml.Name `xml:"obs"`
    IndexDateString string   `xml:"indexDateString"`
    StatusCode      string   `xml:"statusCode"`
    Value           string   `xml:"value"`
}

type Response struct {
    XMLName         xml.Name `xml:"GetSeriesResponse"`
    GetSeriesResult struct {
        XMLName xml.Name `xml:"GetSeriesResult"`
        Series  struct {
            XMLName    xml.Name `xml:"Series"`
            FameSeries struct {
                XMLName xml.Name `xml:"fameSeries"`
                Obs     []Obs
            }
        }
    }
}

of course you must set correct data types for Obs fields )

and yes, you can shortcut XMLName tags like this:

type Response struct {
    XMLName         xml.Name `xml:"GetSeriesResponse"`
    GetSeriesResult struct {
        Series struct {
            FameSeries struct {
                Obs []Obs `xml:"obs"`
            } `xml:"fameSeries"`
        } `xml:"Series"`
    } `xml:"GetSeriesResult"`
}

@tiaguinho this issue is stale and resolved. You can close it, I think...
