英文:
Golang XML etree: Unexpected <></> when adding outer layer
问题
我尝试使用名为https://github.com/beevik/etree的golang库向我的XML中添加外部XML。假设我的XML是<Foo></Foo>，但是当尝试添加外层时，会出现一个额外的空标签，如<></>。如何移除它？
这是我的代码片段：
https://go.dev/play/p/z6E5Ha3hWmm
结果是：
<soap:Envelope>
<soap:Header/>
<soap:Body/>
<><Foo/></>
</soap:Envelope>
我期望的结果是：
<soap:Envelope>
<soap:Header/>
<soap:Body/>
<Foo/>
</soap:Envelope>
在<Foo/>之间有<></>。
编辑
<Foo/>是动态的，所以它可以是<Bar/>或其他任何内容。
英文:
I tried to add outer XML to my XML using golang library that is called https://github.com/beevik/etree
assume my XML is <Foo></Foo> but when trying to add the outer layer there's an additional empty tag like <></>
how to remove that?
Here's my snippet:
https://go.dev/play/p/z6E5Ha3hWmm
and the result is
<soap:Envelope>
<soap:Header/>
<soap:Body/>
<><Foo/></>
</soap:Envelope>
I expected the result is
<soap:Envelope>
<soap:Header/>
<soap:Body/>
<Foo/>
</soap:Envelope>
There's <></> between <Foo/>
EDIT
The <Foo/> is dynamic, so it can be <Bar/> or anything else

原文：Turns out, I just need to add .Root()
So it should be soapBody.AddChild(result.Root())
翻译结果：原来如此，我只需要添加.Root()。
所以应该是soapBody.AddChild(result.Root())。
英文:
Turns out, I just need to add .Root()
So it should be soapBody.AddChild(result.Root())

我对etree比对golang更熟悉，所以你可能需要对以下内容持保留态度（并重新编写），但你需要完成一些基本的与xml相关的操作：
首先，你需要将<Foo>元素包装在一个根元素中，以使其成为一个格式良好的xml文档，然后在该文档中选择该元素。
其次，在第二个（root）文档中，选择要添加<Foo>元素的位置，然后将其添加进去。
代码应该如下所示：
result := etree.NewDocument()
root := etree.NewDocument()
root.ReadFromString("<soap:Envelope><soap:Header/><soap:Body/></soap:Envelope>")
result.ReadFromString("<root><Foo/></root>")
source := result.FindElements("//Foo")[0]
destination := root.FindElements("//soap:Envelope")[0]
destination.AddChild(source)
英文:
I'm far more familiar with etree than with golang, so you may have to take the following with a grain (or two) of salt (and re-write it), but you need to do a couple of basic xml-related things:
First, you have to wrap your <Foo> element in a root element to make it well formed xml document and then, inside that document, select that element.
Second, in the second (root) document, select the location where you want the <Foo> element to be added and then add it.
So it should look like this:
result := etree.NewDocument()
root := etree.NewDocument()
root.ReadFromString("<soap:Envelope><soap:Header/><soap:Body/></soap:Envelope>")
result.ReadFromString("<root><Foo/></root>")
source := result.FindElements("//Foo")[0]
destination := root.FindElements("//soap:Envelope")[0]
destination.AddChild(source)
