- Added package.json to manage development scripts. - Updated restart-services.ps1 to call the new dev script for starting services. - Refactored start-admin.ps1, start-backend.ps1, start-frontend.ps1, and start-mcp.ps1 to utilize the dev script for starting respective services. - Enhanced stop-services.ps1 to improve process termination logic by matching command patterns.

# 开始之前
|
||
|
||
```go
|
||
import "encoding/xml"
|
||
```
|
||
|
||
## 简单的`Xml`解析
|
||
|
||
### 1.假设我们解析的`Xml`内容如下:
|
||
|
||
```xml
|
||
<feed>
|
||
<person name="initcool" id="1" age=18 />
|
||
</feed>
|
||
```
|
||
|
||
<!--more-->
|
||
|
||
### 2.接着我们构造对应的结构体
|
||
|
||
```go
|
||
type Feed struct {
|
||
XMLName xml.Name `xml:"feed"`
|
||
Person struct{
|
||
Name string `xml:"name"`
|
||
Id string `xml:"id"`
|
||
Age int `xml:"age"`
|
||
} `xml:"person"`
|
||
}
|
||
```
|
||
|
||
### 3.对`Xml`数据进行反序列化
|
||
|
||
```go
|
||
var feed Feed
|
||
|
||
// 读取Xml文件，并返回字节流
|
||
content,err := ioutil.ReadFile(XmlFilename)
|
||
if err != nil {
|
||
log.Fatal(err)
|
||
}
|
||
|
||
// 将读取到的内容反序列化到feed
|
||
xml.Unmarshal(content,&feed)
|
||
```
|
||
|
||
## 带有命名空间的`Xml`解析
|
||
|
||
部分`xml`文件会带有`命名空间`(`Namespace`),也就是冒号左侧的内容,此时我们需要在`go`结构体的`tag` 中加入`命名空间`。
|
||
|
||
### 1.带有命名空间(Namespace)的`Xml`文件
|
||
|
||
```xml
|
||
<feed xmlns:yt="http://www.youtube.com/xml/schemas/2015" xmlns:media="http://search.yahoo.com/mrss/" xmlns="http://www.w3.org/2005/Atom">
|
||
<!-- yt即是命名空间 -->
|
||
<yt:videoId>XXXXXXX</yt:videoId>
|
||
<!-- media是另一个命名空间 -->
|
||
<media:community></media:community>
|
||
</feed>
|
||
```
|
||
|
||
### 2.针对命名空间构造结构体
|
||
|
||
```go
|
||
type Feed struct {
|
||
XMLName xml.Name `xml:"feed"` // 指定最外层的标签为feed
|
||
VideoId string `xml:"http://www.youtube.com/xml/schemas/2015 videoId"`
|
||
Community string `xml:"http://search.yahoo.com/mrss/ community"`
|
||
}
|
||
```
|
||
|
||
### 3.对`Xml`数据进行反序列化
|
||
|
||
```go
|
||
var feed Feed
|
||
|
||
// 读取Xml文件，并返回字节流
|
||
content,err := ioutil.ReadFile(XmlFilename)
|
||
if err != nil {
|
||
log.Fatal(err)
|
||
}
|
||
|
||
// 将读取到的内容反序列化到feed
|
||
xml.Unmarshal(content,&feed)
|
||
```
