golang xml marshal对应的struct两种表示方法

概述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.filterstype Project struct { ToolsVersion string `xml:"ToolsVersion,attr"` Xmlns string `xml:"xmlns,attr"` Item

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.filterstype 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}

<?xml version="1.0" enCoding="UTF-8"?><Project Toolsversion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">	<ItemGroup>		<Filter Include="pub">			<UniqueIDentifIEr>{470d3840-f2c2-4c5b-430f-e9d745bcc309}</UniqueIDentifIEr>		</Filter>		<Filter Include="src">			<UniqueIDentifIEr>{446a4d3d-d7e0-4ad9-7cf9-917fbba3cf8b}</UniqueIDentifIEr>		</Filter>		<Filter Include="pub\base">			<UniqueIDentifIEr>{1281d07c-e739-4f48-502d-54211f00ae19}</UniqueIDentifIEr>		</Filter>		<Filter Include="pub\driver">			<UniqueIDentifIEr>{d43ac9c6-a8f0-4484-5811-927daab37970}</UniqueIDentifIEr>		</Filter>		<Filter Include="pub\protocol">			<UniqueIDentifIEr>{35a150d1-33f3-4a98-5f0b-bb71982506ec}</UniqueIDentifIEr>		</Filter>		<Filter Include="pub\st_lib">			<UniqueIDentifIEr>{3e64a85e-249d-4a03-521e-4b5813b40edd}</UniqueIDentifIEr>		</Filter>		<Filter Include="pub\startup">			<UniqueIDentifIEr>{6cd70ce7-0c9c-4582-60e7-9e9b420aa43a}</UniqueIDentifIEr>		</Filter>		<Filter Include="pub\w5500">			<UniqueIDentifIEr>{bafafc00-7fb5-4ccb-4b30-5511fe90a3cd}</UniqueIDentifIEr>		</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.filterstype 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}

<?xml version="1.0" enCoding="UTF-8"?><Project Toolsversion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">	<ItemGroup>		<Filter Include="pub">			<UniqueIDentifIEr>{a0e40766-d234-4847-4772-a9b08d2fb21e}</UniqueIDentifIEr>		</Filter>		<Filter Include="src">			<UniqueIDentifIEr>{7fa4c884-635d-4e65-5bf9-c692ba305c9e}</UniqueIDentifIEr>		</Filter>		<Filter Include="pub\base">			<UniqueIDentifIEr>{e4821dfa-f228-4150-58fa-4bee90398973}</UniqueIDentifIEr>		</Filter>		<Filter Include="pub\driver">			<UniqueIDentifIEr>{f00ff500-af7f-4c11-703f-3e5f17e5c74b}</UniqueIDentifIEr>		</Filter>		<Filter Include="pub\protocol">			<UniqueIDentifIEr>{26776cca-98bd-4b46-56f8-882a0aa73cd7}</UniqueIDentifIEr>		</Filter>		<Filter Include="pub\st_lib">			<UniqueIDentifIEr>{d3a26e89-26d5-4d33-7a87-aea134553ac8}</UniqueIDentifIEr>		</Filter>		<Filter Include="pub\startup">			<UniqueIDentifIEr>{460fb330-ba31-4d5f-7060-b4719e560dc9}</UniqueIDentifIEr>		</Filter>		<Filter Include="pub\w5500">			<UniqueIDentifIEr>{bc43b180-e95a-4ed2-7031-5bc686e65132}</UniqueIDentifIEr>		</Filter>	</ItemGroup></Project>

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://schemas.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(" ")}
