golang xml marshal對應的struct兩種表示方法

這是一個建立於 的文章，其中的資訊可能已經有所發展或是發生改變。

1.xml的節點名字就是struct成員的名字，如：Project.ItemGroup，成員的類型名不影響

//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節點的名字是struct的tag名字

xml的ItemGroup使用`xml:"ItemGroup"`標註的方法，注意只需要給slice的名字標註就可以了，具體的slice類型名字隨便取

//vcxproj.filterstype Project struct {ToolsVersion string        `xml:"ToolsVersion,attr"`Xmlns        string        `xml:"xmlns,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>

以上測試使用的代碼（注意兩種情況下struct的成員名字變化了需要簡單的修改下代碼）

func TestFilters(t *testing.T) {var prj Projectprj.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 = filtersfor 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(" ")}
