[Caml-list] Manipulating xml files withing ocaml

[Jean Krivine]

Just a quick question, I would like to open and access easily an xml
file within my ocaml program. Does someone have a small library that
would help me doing that? All the things I found for now are
libraries that help me construct xml and check for consistency which
is not what I want.

Thanks!
Jean

If the xml you intend to parse is not too broken (like html for instance),

you can try to use xml-light, whose APIis very simple.

Superb that seems to be what I needed thanks!

PXP may be a better choice. It's harder at first, but not much and
could be worth the five additionnal minutes required to learn it. It
handles unicode and is still maintained (among others).

Indeed. If you find yourself routinely having to deal with XML,
and if you need more advanced features such as validating very
complex DTDs, than learning PXP is well worth it (Xml-light
will choke on all but the simplest DTDs).

If you are doing heavy manipulation of XML and wished for a
more "native" support in the language, then take a look at
Cduce/Ocamlduce.

Finally, if you just need to parse a simple XML file and this
is a one-off event, then Xml-light is indeed the simplest option.

In my case I just want to parse a small xml file and I don't need to
check for consistency so I think xml-light is fine enough. Thank you
for the references though

One more choice is Xmlm:

It is simpler than pxp and more complete/correct than xml-light.

For these topics about comparing libraries, there is an attempt at
collaborative work to build quick but comprehensive overview :

About the current question (XML), you can find there the names of a few
other tools.
