大佬教程收集整理的这篇文章主要介绍了golang xml marshal对应的struct两种表示方法，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

1.xml的节点名字就是struct成员的名字，如：Project.ItemGroup，成员的类型名不影响

//vcxproj.filters
type Project struct {
	ToolsVersion String        `xml:"ToolsVersion,attr"`
	Xmlns        String        `xml:"xmlns,attr"`
	ItemGroup    []FilterGroup //`xml:"ItemGroup"`
}

type FilterGroup struct {
	Filter []Filter //`xml:"Filter"`
}

type Filter struct {
	Include          String `xml:"Include,attr"`
	UniquEIDentifier String
}

<Project ToolsVersion="4.0" xmlns="http://scheR_1000_11845@as.microsoft.com/developer/msbuild/2003">

		<Filter Include="pub">

		</Filter>
	</ItemGroup>
</Project>

2. xml节点的名字是struct的tag名字

xml的ItemGroup使用`xml:"ItemGroup"`标注的方法，注意只需要给slice的名字标注就可以了，具体的slice类型名字随便取

//vcxproj.filters
type Project struct {
	ToolsVersion String        `xml:"ToolsVersion,attr"`
	FilterGroups []FilterGroup `xml:"ItemGroup"`
}

type FilterGroup struct {
	Filter []Filter //`xml:"Filter"`
}

type Filter struct {
	Include          String `xml:"Include,attr"`
	UniquEIDentifier String
}

以上测试使用的代码（注意两种情况下struct的成员名字变化了需要简单的修改下代码）

func TestFilters(t *tesTing.T) {

	var prj Project
	prj.ToolsVersion = "4.0"
	prj.Xmlns = "http://scheR_1000_11845@as.microsoft.com/developer/msbuild/2003"
	prj.ItemGroup = make([]FilterGroup,1)

	filter_strs := []String{"pub","src","pub\\base","pub\\driver","pub\\protocol","pub\\st_lib","pub\\startup","pub\\w5500"}

	filters := make([]Filter,len(filter_strs))

	prj.ItemGroup[0].Filter = filters

	for i := 0; i < len(filters); i++ {
		f := &filters[i]
		f.Include = filter_strs[i]
		uid,_ := uuid.NewV4()
		f.UniquEIDentifier = fmt.Sprintf("{%s}",uid.String())
	}
	data,err := xml.MarshalIndent(&prj,"","\t")
	if err != nil {
		fmt.Println(err)
		return
	}
	fmt.Print(xml.Header)
	fmt.Println(String(data))
	t.Error(" ")
}
