XML support

[xancorreu]

Hi,

For my personal project (ditz clone) I want to store things in XML. I
see library reference and no xml library is present. Is there a
short-term planning for implementing that?

Thanks a lot for your support,
Xan.

An XML parser is one of the top items on my personal library wish
list, but until now I haven't needed it in my own projects, so I have
focused on other things.

I have found that often it's actually very easy to write a parser for
a simple text-based file format using only things like regular
expressions and Str split, and the data files can be easier to read
and edit manually thank XML.

For example, instead of

<data>
<item>
<name>foo</name>
<size>3</size>
</item>
...
</data>

you could use something like this

name: foo
size: 3
--
...

Of course this is mostly valid for relatively simple data formats. XML
is a win if you have complex recursive data structures, for example.

Can I use a C-API and import xml library in c or c++?
I want XML. There is good known about it and we have a bunch of tools for exporting or importing....

Yes, writing a wrapper for expat (for example) using the C API would
be straightforward. The only potentially complex thing that I can see
is if you want to pass callbacks to a C/C++ lib that call Alore code.
Just ask about it if you have any questions; I'm happy to help.

XML is useful but sometimes I feel it is a bit overused. ;-)

I'm thinking in TinyXML2. Do you know any good and tiny XML library in C
or C++?
Thanks for the offering. I will need much help.

I will try it. First I have to read this

But it's standard de facto ;-)
