Note, libxml2 actually only supports XPath 1, not XPath 2.
However,
/descendant::node()/rec/child::node()[1]
will match text nodes, and you're getting the blank (whitespace-only)
text node that's the first child of elements, since your input is
"indented".

No.
The first child node in
<rec id="1">
<para type="error" position="1"/>
is the newline and spaces between id="1"> and <para.
