Re: How to insert a set nodes under the root of an ar

The first match I gave is a match on the document node; / is the root node, /* is the document node, at least per XPath 2 terminology. XPath 1 is of course using different terminology.:)
Not quite. "/" is both "the root node" (when you know what tree you're talking about" and "a document node" (when you don't).
/* (short for /child::*) is the "document element" of a well-formed XML instance, but we also see trees (for example, it's not uncommon in temporary trees) that have more than one element child of the root; and this XPath will select all of them.
Such trees can be serialized and called into documents as external parsed entities, but they won't be complete documents in themselves, due to the well-formedness constraint on the XML format.
