I have an XML, which can be like
<?xml version="1.0" encoding="utf-8"?>
<testnode type="1">123</testnode>
or like
<?xml version="1.0" encoding="utf-8"?>
<othernode attrib="true">other value</othernode>
or the root node can be something completely unexpected. (Theoretically anything.) I'm using REXML to parse it. How can I find out what XML node is the root element?
