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"`
					IndexDateString string `xml:"indexDateString"`
					StatusCode      string `xml:"statusCode"`
					Value           string `xml:"value"`
				} `xml:"obs"`
			} `xml:"fameSeries"`
		} `xml:"Series"`
	} `xml:"GetSeriesResult"`
} 

Try 2

type GetSeriesResponse struct {
	GetSeriesResult string `xml:"GetSeriesResult"`
}

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

@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 )

[oxyii]

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...
