|
||||
|
||||
Go package that converts XML to JSON
|
||||
|
||||
### Install
|
||||
|
||||
go get -u github.com/basgys/goxml2json
|
||||
|
||||
### Importing
|
||||
|
||||
import github.com/basgys/goxml2json
|
||||
|
||||
### Usage
|
||||
|
||||
**Code example**
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"strings"
|
||||
|
||||
xj "github.com/basgys/goxml2json"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// xml is an io.Reader
|
||||
xml := strings.NewReader(`<?xml version="1.0" encoding="UTF-8"?><hello>world</hello>`)
|
||||
json, err := xj.Convert(xml)
|
||||
if err != nil {
|
||||
panic("That's embarrassing...")
|
||||
}
|
||||
|
||||
fmt.Println(json.String())
|
||||
// {"hello": "world"}
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
**Input**
|
||||
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8"?>
|
||||
<osm version="0.6" generator="CGImap 0.0.2">
|
||||
<bounds minlat="54.0889580" minlon="12.2487570" maxlat="54.0913900" maxlon="12.2524800"/>
|
||||
<foo>bar</foo>
|
||||
</osm>
|
||||
```
|
||||
|
||||
**Output**
|
||||
|
||||
```json
|
||||
{
