\usage{
guess_structure(xml_node, xpath_expr, subclasses_names = character())
}
\arguments{
\item{xml_node}{xml2::xml_node: XML node}

\item{xpath_expr}{string: XPath expression (for subclass differentiation)}

\item{subclasses_names}{Optional: character: Names of r2ogs6 subclasses
(r2ogs6 classes without a OGS6$add method)}
}
\description{
Guesses the R representation of an XML node and adds it to
parameter list. This is a recursive function.
ASSUMPTIONS:
1) Leaf nodes will have EITHER a value OR attributes (and will not be missing
both, e.g. '<a/>').
2) Leaf nodes will never be r2ogs6_* objects
3) If there are multiple occurrences of r2ogs6_* class (and subclass)
elements on the same level, they have a wrapper node as their parent
(e.g. <processes>, <properties>) which  will contain ONLY elements of this
type
4) Wrapper nodes are represented as lists
5) Parent nodes whose children have no children are represented as lists
