Re: [Vala] [Genie] Using MarkupParser

[Nicolas <c r n a wanadoo fr>]

Hey Patrick,

I'm not alone going on all interesting forums !

I can't really help you because i'm learning programmation like you.

I see on the libxml2 example page a function to clean the Xml.Doc:

xmlFreeDoc(yourdoc)

But vala has on its libxml2.vapi, this:

[CCode (cname = "xmlDoc", free_function = "xmlFreeDoc", cheader_filename 
= "libxml/tree.h,libxml/parser.h")]
probably the "free_function" is for cleaning automatically the doc when 
vala generate c source file ?!?!

For the node, i don't know, for example this:
http://xmlsoft.org/examples/tree1.c
use a node, and i don't see a cleanup function.

Nicolas.
