Go 的新手,必须使用“encoding/xml”包中的 xml.MarshalIndent 创建 xml 文件。一个要求是像这样创建一个标签:
`
<Attributes>
<Attribute name="Me">I really like this GO lang</Attribute>
<Attribute name="problem">the xml package is not behaving</Attribute>
</Attributes>
`
一组带有值和属性的标签,但无论我做什么(我尝试了很多不同的方法),我就是无法让它工作。
我编写的代码生成了这个: `
<Attributes>
<Attribute Name="J3K Solutions">
<Attribute>IT Support</Attribute>
</Attribute>
<Attribute Name="stakoverflow">
<Attribute>The place I go for help</Attribute>
</Attribute>
</Attributes>
`
但是我需要它看起来像这样: `
<Attributes>
<Attribute Name="J3K Solutions" >IT Support</Attribute>
<Attribute Name="stakoverflow" >The place I go for help</Attribute>
</Attributes>
` 我一直在阅读文档,并试图让它工作几个小时。 有人知道这是否可行吗?
代码:
package main
import (
"encoding/xml"
"fmt"
"time"
)
type attributes struct {
Name string `xml:",attr"`
Attribute string `xml:"Attribute"`
}
type fXML struct {
MessageID string `xml:"MessageID,attr"`
Timestamp string `xml:"timestamp,attr"`
Version string `xml:"version,attr"`
Header struct {
From struct {
Credential struct {
Domain string `xml:"domain,attr"`
Identity string `xml:"Identity"`
} `xml:"Credential"`
} `xml:"From"`
To struct {
Credential struct {
Domain string `xml:"domain,attr"`
Identity string `xml:"Identity"`
} `xml:"Credential"`
} `xml:"To"`
Attributes struct {
Attribute []attributes
}
} `xml:"Header"`
}
func main() {
rdata := &fXML{}
t := time.Now()
rdata.MessageID = "I'm really liken this GO language!"
rdata.Timestamp = t.Format("2006-01-02T15:04:05")
rdata.Version = "1.0"
rdata.Header.From.Credential.Domain = "j3ksolutions.com"
rdata.Header.From.Credential.Identity = "J3K Solutions"
rdata.Header.To.Credential.Domain = "stackoverflow.com"
rdata.Header.To.Credential.Identity = "stackoverflow"
rdata.Header.Attributes.Attribute = append(rdata.Header.Attributes.Attribute,
attributes{
Name: "J3K Solutions",
Attribute: "IT Support and Custom Programing",
})
rdata.Header.Attributes.Attribute = append(rdata.Header.Attributes.Attribute,
attributes{
Name: "stakoverflow",
Attribute: "The place I go for help",
})
if m, err2 := xml.MarshalIndent(rdata, "", "\t"); err2 != nil {
panic("xml.MarshalIndent FAILED: " + err2.Error())
} else {
xmlheader := fmt.Sprintf("<?xml version=\"1.0\" encoding=\"ISO-8859-1\" ?>\n")
m = append([]byte(xmlheader), m...)
fmt.Printf("\n%s\n\n", m)
}
}
最佳答案
您可能需要使用“,chardata”结构标签来写入字符数据。这是doc说
- a field with tag ",chardata" is written as character data, not as an XML element.
您可以按如下方式定义结构
type attributes struct {
XMLName xml.Name `xml:Attribute"`
Name string `xml:",attr"`
Attribute string `xml:",chardata"`
}

关于xml - GOLang XML 无法使用 xml.MarshalIndent 在一个标记中创建值和属性,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/41867529/
