1. The goal is

Use go analysis xmind, Later can be converted to excel, Or generate automatic execution steps, etc

2. xmind Examples

3. Code

package main

import (
	"archive/zip"
	"encoding/json"
	"io/ioutil"
	"log"
)

const (
	fullFilename    = "XX System test cases .xmind"
	contentFilename = "content.json"
)

type (
	Topic struct {
		Id       string `json:"id"`
		Title    string `json:"title"`
		Children struct {
			Attached []Topic `json:"attached"`
		} `json:"children"`
	}

	Sheet struct {
		Id        string `json:"id"`
		Class     string `json:"class"`
		Title     string `json:"title"`
		RootTopic Topic  `json:"rootTopic"`
	}
)

func main() {
	zipFp, zipErr := zip.OpenReader(fullFilename)
	if zipErr != nil {
		log.Fatalf("Failed to open zip file %s: %s\n", fullFilename, zipErr)
	}

	sheets := make([]Sheet, 0)
	for _, file := range zipFp.File {
		if file.FileInfo().Name() != contentFilename {
			continue
		}

		contentFp, openErr := file.Open()
		if openErr != nil {
			log.Fatalf("Failed to open file %s: %s\n", contentFilename, openErr)
		}

		contentByte, readErr := ioutil.ReadAll(contentFp)
		if readErr != nil {
			log.Fatalf("Failed to read file %s: %s\n", contentFilename, readErr)
		}

		jsonErr := json.Unmarshal(contentByte, &sheets)
		if jsonErr != nil {
			log.Fatalf("Failed to parse json to Sheet: %s\n", jsonErr)
		}

		prettyJson, _ := json.MarshalIndent(sheets, "", "  ")
		log.Println(string(prettyJson))
	}
}

Output
