pars_new() instantiates a new pars node.
pars_type() checks if the node is a pars node.
pars_seq_get() returns all the child nodes as a list.
pars_get() returns node at position index.
pars_set() sets node at position index and deletes the previous node.
pars_rep() sets node at position index and returns the previous node.
pars_ins() inserts nodes starting from position index.
