[英]Problems decoding XML in go
I have a question regarding unmarshalling of XML in Go. 我有一个关于在Go中解组XML的问题。
I have been trying to unmarshal this piece of XML 我一直试图解组这段XML
<?xml version="1.0" encoding="UTF-8"?>
<response>
<folders>
<folder id="78" name="Test 1" />
<folder id="95" name="Test 2" />
<folder id="96" name="Test 3" />
</folders>
</response>
These are my structs 这些是我的结构
type XmlResponse struct {
Folders []Folder `xml:"folders"`
}
type Folder struct {
XMLName xml.Name `xml:"folder"`
Id int `xml:"id,attr"`
Name string `xml:"name, attr"`
}
For some reason, Go won't unmarshal each folder into an array of folders, as defined in the struct. 出于某种原因,Go不会将每个文件夹解组为文件夹数组,如结构中所定义。 Instead i get the message
相反,我收到了消息
"expected element type <folder> but have <folders>"
As you can see, i have added xml:"folders"
to the list of folders, but it still won't recognize it correctly. 如您所见,我已将
xml:"folders"
添加到文件夹列表中,但仍无法正确识别它。 I have tried to place the XMLName attributes in different places but i either end up with the above error, or just an empty XmlResponse struct. 我试图将XMLName属性放在不同的位置,但我最终得到上面的错误,或者只是一个空的XmlResponse结构。 I have also tried to make a Folders struct containing an array of Folders, with the same result.
我还尝试创建一个包含文件夹数组的Folders结构,结果相同。 Am i conceptually missing something regarding XML decoding?
我在概念上缺少关于XML解码的东西吗? Are the names maybe a little too close to eachother?
名字可能有点太靠近了吗?
I have made an example on Go playground that shows the issue: http://play.golang.org/p/XRCGVNzO_O 我在Go操场上做了一个例子来说明问题: http : //play.golang.org/p/XRCGVNzO_O
Thank you very much. 非常感谢你。
You need to change the xml:"folders"
meta to xml:"folders>folder"
to match the folder
elements inside the folders
element. 您需要更改的
xml:"folders"
元到xml:"folders>folder"
相匹配的folder
里面的元素folders
元素。
