having trouble with gegl_node_to_xml

hello,

I am having trouble to save gegl operations to repeat them later. I
think, that gegl_node_to_xml is the operation I am looking for, but this
can be wrong.

I wrote this small program:

#include <stdio.h>
#include <gegl.h>

gint
main (gint argc,
      gchar **argv)
{
    GeglNode *gegl, *gn_load, *gn_save, *gn_op;
    gchar* xmltext;

    g_thread_init (NULL);
    gegl_init (&argc, &argv);

    gegl = gegl_node_new ();
    gn_load = gegl_node_new_child(gegl, "operation", "gegl:load",
"path", "bsp-900x600.jpg", NULL);
    gn_save = gegl_node_new_child(gegl, "operation", "gegl:jpg-save",
"path", "out.jpg", NULL);
    gn_op   = gegl_node_new_child(gegl, "operation",
"gegl:unsharp-mask", "std-dev", 1.2, "scale", 8.0, NULL);
    gegl_node_link_many (gn_load, gn_op, gn_save, NULL);
    gegl_node_process (gn_save);
