How to tell if an empty XML node has been found?

问题

我有一个像这样的XML:

<list>
<entry><string>...</string><string>...</string></entry>
<entry><string>...</string><string></string></entry>
<entry><string>...</string><null/></entry>
<entry><string>...</string><string>...</string><null/></entry>
</list>

如何判断我是否有一个<null/>元素?这是我试图处理的结构:

type Entry struct {
    Values []string `xml:"string"`
    Null   string   `xml:"null"`
}
英文:

I have XML like this:

<list>
<entry><string>...</string><string>...</string></entry>
<entry><string>...</string><string></string></entry>
<entry><string>...</string><null/></entry>
<entry><string>...</string><string>...</string><null/></entry>
</list>

How to tell that I had a <null/> element? This is the struct I'm trying to work with:

type Entry struct {
    Values []string `xml:"string"`
    Null   string   `xml:"null"`
}
