netclient support only the http protocol.
curl supports in addition https, ftp, and other protocols.
* You can also use the expat parser instead of PXP to load XML documents
(PXP is still needed):

Note on using the expat parser
Note on XML parsers
------------------------------------------------------------------------------
CDuce can uses two XML parsers: PXP and expat. PXP is needed
to build CDuce, and expat support can be additionnaly added.
When CDuce is built with expat support, it uses by default expat to
load XML files. You can still use PXP by adding "--no expat" to
When CDuce is built with support for both expat and PXP, it uses by default
expat to parse XML files. You can still use PXP by adding "--no expat" to
the CDuce command line.
Note: the current wrapper for expat does not support inclusion
of external entities. Moreover, the error messages in case of
ill-formed XML are less informative than PXP's.
- error messages:
The error messages provided by expat when parsing ill-formed XML documents
are less informative than those given by PXP.
- efficiency:
* expat is more efficient than PXP, and produces smaller executables.
* for PXP, ocamllex lexers are more efficient than wlex lexers.
