No, XPath provides a way to reference nodes in a tree that is implied by
an XML document, and it mandates functions that return objects of type
boolean, number, string, or node-set. i.e., it is 'read-only'.

Tree construction is handled by XSLT, which extends XPath by adding more
functions, another object type, an XML vocabulary with additional
semantics, and a processing model.

People want to call this construction 'transformation', but I think that's
really a misnomer, since you never actually modify anything. Instead, you
create a new node tree (or node tree fragments) that *may* be based upon
information that XPath expressions helped you obtain from the original
tree(s).
