Data validation tool, a simplified version of XML schema.
- Support Date and Time data format
- Export definition into XSD format

}validate data by loading schema definition from XML and input data from JSON string
//define XML schema
defRaw := `
<dxdoc name="invoice" revision="1" id="7">
<dxstr name="invNo"></dxstr>
<dxint name="totalQty" isOptional="true"></dxint>
<dxdecimal name="price" precision="2"></dxdecimal>
</dxdoc>`
//parse XML schema into GO instance
dxdoc, dxErr := document.DecodeDxXML(defRaw)
if dxErr != nil {
panic(dxErr) //show parsed failed message
}
//define input data (JSON string)
inputJSON := `
{
"invNo": "abcd",
"totalQty": 3,
"price": 12.58
}`
//convert JSON string into GO generic MAP instance
rawInput := make(map[string]interface{})
jsonErr := json.unmarshal([]byte(inputJSON), &rawInput)
//validate input data
validateErr := dxdoc.ValidateData(rawInput)
if validateErr != nil {
log.Println(validateErr.Error()) //show invalid data message
} else {
log.PrintLn("input data is valid")
}Validate data by direct define definition and input data
//define definition
dxdoc := document.DxDoc{

Revision: 1,
ID: 7,
Items: []document.DxItem{
document.DxStr{Name: "invNo", EnableLenLimit: true, LenLimit: 4},
document.DxInt{Name: "totalQty", IsOptional: true},
document.DxDecimal{Name: "price", Precision: 2},
},
}
//define input data
rawInput := map[string]interface{}{
"invNo": "abcd",
"totalQty": 3,
"price": 12.58,
}
//validate input data
validateErr := dxdoc.ValidateData(rawInput)
if validateErr != nil {
log.Println(validateErr.Error()) //show invalid data message
} else {
log.PrintLn("input data is valid")
