xml2map
XML to MAP converter written Golang
Sometimes there is a need for the representation of previously unknown structures. Such a universal representation is usually a string in the form of JSON, XML, or the structure of data map. similar to the map[string]interface{} or map[interface{}]interface{}.
This is a converter from the old XML format to map[string]interface{} Golang
For example, the map[string]interface{} can be used as a universal type in template generation. Golang "text/template" and etc.
Getting started
1. install
go get -u github.com/sbabiv/xml2map
Or, using dep:
dep ensure -add github.com/sbabiv/xml2map
2. use it
func main() {
data := `<container uid="FA6666D9-EC9F-4DA3-9C3D-4B2460A4E1F6" lifetime="2019-10-10T18:00:11">
<cats>
<cat>
<id>CDA035B6-D453-4A17-B090-84295AE2DEC5</id>
<name>moritz</name>
<age>7</age>
<items>
<n>1293</n>
<n>1255</n>
<n>1257</n>
</items>
</cat>
<cat>
<id>1634C644-975F-4302-8336-1EF1366EC6A4</id>
<name>oliver</name>
<age>12</age>
</cat>
<dog color="gray">hello</dog>
</cats>
<color>white</color>
<city>NY</city>
</container>`
decoder := xml2map.NewDecoder(strings.NewReader(data))
result, err := decoder.Decode()
if err != nil {
fmt.Printf("%v\n", err)
} else {
fmt.Printf("%v\n", result)
}
v := result["container"].
(map[string]interface{})["cats"].
(map[string]interface{})["cat"].
([]map[string]interface{})[0]["items"].
(map[string]interface{})["n"].([]string)[1]
fmt.Printf("n[1]: %v\n", v)
}
if you want to use your custom prefixes use the
NewDecoderWithPrefix(reader io.Reader, attrPrefix, textPrefix string) *Decoder
Output
map[container:map[@uid:FA6666D9-EC9F-4DA3-9C3D-4B2460A4E1F6 @lifetime:2019-10-10T18:00:11 cats:map[cat:[map[id:CDA035B6-D453-4A17-B090-84295AE2DEC5 name:moritz age:7 items:map[n:[1293 1255 1257]]] map[id:1634C644-975F-4302-8336-1EF1366EC6A4 name:oliver age:12]] dog:map[@color:gray #text:hello]] color:white city:NY]]
