Hello everone, after Unmarshaling the XmlVast that I get from an URL that's give just the struct but without any value. even when i copy the content of the XmlVast in a file and I try to Unmarshal it it give me the same responce the struct without any value.
Thank you in advance.
You are trying to unmarshal an xml document with a root of <VAST> into a struct of type VastHtml, which contains VAST as its first field.
Pass the VAST element directly to the Unmarshal function if that is what you want to decode into.
err = xml.Unmarshal(xmlDataFromHttp, &xmlData.VAST)
The XML input has a <VAST> element at the root -- this corresponds to the VastHtml.VAST field in your struct. So, pass that to xml.Unmarshal as the target value:
err = xml.Unmarshal(xmlDataFromHttp, &xmlData.VAST)
(I agree with Lander that the deeply-nested struct definition is going to be a problem going forward).
