static xmlNodePtr get_xlink_node(xmlNodePtr xnode)
Return a xmlNodePtr on a node referenced by a XLink or NULL otherwise.
static bool is_xlink(xmlNodePtr node)
Return true if current node contains a simple XLink Return false otherwise.
static LWGEOM * parse_gml(xmlNodePtr xnode, bool *hasz, int *root_srid)
