Go XML unmarshal array

问题

我正在尝试解析一个看起来像这样的文件：

  1. <?xml version="1.0" encoding="UTF-8"?>
  2. <houses>
  3.   <house name="Rhyves Flats 14" houseid="1" entryx="167" entryy="361" entryz="6" rent="0" townid="2" size="17" />
  4. </houses>

使用以下代码：

  1. // House struct used for houses xml file
  2. type House struct {
  3.     XMLName xml.Name `xml:"houses"`
  4.     HouseID uint32 `xml:"houseid,attr"`
  5.     Name    string `xml:"name,attr"`
  6.     EntryX  uint16 `xml:"entryx,attr"`
  7.     EntryY  uint16 `xml:"entryy,attr"`
  8.     EntryZ  uint16 `xml:"entryz,attr"`
  9.     Size    int    `xml:"size,attr"`
  10.     TownID  uint32 `xml:"townid,attr"`
  11.     Rent    int    `xml:"rent,attr"`
  12. }
  14. // LoadHouses parses the server map houses
  15. func LoadHouses(file string, list []House) error {
  16.     // Load houses file
  17.     f, err := ioutil.ReadFile(file)
  19.     if err != nil {
  20.         return err
  21.     }
  23.     // Unmarshal houses file
  24.     return xml.Unmarshal(f, &list)
  25. }

这没有返回任何错误。但是房屋切片是空的。一切似乎都正确，属性也被设置了，XMLName也是正确的。

I am trying to unmarshal a file that looks like this

  1. &lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
  2. &lt;houses&gt;
  3.   &lt;house name=&quot;Rhyves Flats 14&quot; houseid=&quot;1&quot; entryx=&quot;167&quot; entryy=&quot;361&quot; entryz=&quot;6&quot; rent=&quot;0&quot; townid=&quot;2&quot; size=&quot;17&quot; /&gt;
  4. &lt;/houses&gt;

With the following code

  1. // House struct used for houses xml file
  2. type House struct {
  3. 	XMLName xml.Name `xml:&quot;houses&quot;`
  4. 	HouseID uint32 `xml:&quot;houseid,attr&quot;`
  5. 	Name    string `xml:&quot;name,attr&quot;`
  6. 	EntryX  uint16 `xml:&quot;entryx,attr&quot;`
  7. 	EntryY  uint16 `xml:&quot;entryy,attr&quot;`
  8. 	EntryZ  uint16 `xml:&quot;entryz,attr&quot;`
  9. 	Size    int    `xml:&quot;size,attr&quot;`
  10. 	TownID  uint32 `xml:&quot;townid,attr&quot;`
  11. 	Rent    int    `xml:&quot;rent,attr&quot;`
  12. }
  14. // LoadHouses parses the server map houses
  15. func LoadHouses(file string, list []House) error {
  16. 	// Load houses file
  17. 	f, err := ioutil.ReadFile(file)
  19. 	if err != nil {
  20. 		return err
  21. 	}
  23. 	// Unmarshal houses file
  24. 	return xml.Unmarshal(f, &amp;list)
  25. }

This is not returning any error. But the house slice is empty. Everything seems correct, the attrs are set and the XMLName too.

得分: 1

你的代码缺少对XML中Houses部分的定义。类似下面所示的内容，并对其进行解组。

  1. type Houses struct {
  2.     House    []House `xml:"house"`
  3. }
英文:

Your code is missing a definition of the Houses part of the XML. Something like what is shown below and unmarshal on that.

  1. type Houses struct {
  2. 	House    []House `xml:&quot;house&quot;`
  3. }
