GO Encoder用法及代码示例

GO语言"encoding/xml"包中"Encoder"类型的用法及代码示例。

编码器将 XML 数据写入输出流。

用法:

type Encoder struct {
    // contains filtered or unexported fields
}

例子：

package main

import (
    "encoding/xml"
    "fmt"
    "os"
)

func main() {
    type Address struct {
        City, State string
    }
    type Person struct {
        XMLName   xml.Name `xml:"person"`
        Id        int      `xml:"id,attr"`
        FirstName string   `xml:"name>first"`
        LastName  string   `xml:"name>last"`
        Age       int      `xml:"age"`
        Height    float32  `xml:"height,omitempty"`
        Married   bool
        Address
        Comment string `xml:",comment"`
    }

    v := &Person{Id: 13, FirstName: "John", LastName: "Doe", Age: 42}
    v.Comment = " Need more details. "
    v.Address = Address{"Hanga Roa", "Easter Island"}

    enc := xml.NewEncoder(os.Stdout)
    enc.Indent("  ", "    ")
    if err := enc.Encode(v); err != nil {
        fmt.Printf("error: %v\n", err)
    }

}

输出：

  <person id="13">
      <name>
          <first>John</first>
          <last>Doe</last>
      </name>
      <age>42</age>
      <Married>false</Married>
      <City>Hanga Roa</City>
      <State>Easter Island</State>
      <!-- Need more details. -->
  </person>
