perl - XML::Simple 删除根元素

Question

嗨，我有一个从哈希数组中获取的 xml 数据，当我对其执行 Dumper 时，输出如下:

$var1=
    '<Data>
            <Data1>ABC</Data1>
            <Data2>ABCD</Data2>
    </Data>';

我将其放在变量调用 $var1 中。现在我在上面使用 XML::Simple ..它有点像: {Data1=>'ABC',Data2=>'ABCd'};

第一个标签数据消失了。怎么了？

似乎是well-documented :

KeepRoot => 1:

In its attempt to return a data structure free of superfluous detail and unnecessary levels of indirection, XMLin() normally discards the root element name. Setting the KeepRoot option to 1 will cause the root element name to be retained. So after executing this code:

     $config = XMLin('<config tempdir="/tmp" />', KeepRoot => 1)

You'll be able to reference the tempdir as "$config->{config}->{tempdir}" instead of the default "$config->{tempdir}".
