I am new to wireshark and I am trying to upgrade a plugin that was build for 1.x to 2.x. One of those steps is replacing proto_tree_add_text() with proto_tree_add_item()

if the old code is

proto_tree_add_text(foo_tree, tvb, 0, -1, "header ver. %s", header_array[index]);

I know I would have to start with

static hf_register_info hf[] = {
    { &foo_header,
        { "header ver. ", "foo.header",
        NULL, 0x0,
        NULL, HFILL }
proto_tree_add_item(foo_tree, foo_header, tvb, 0, -1, ENC_NA);

But how would I add the array into the string to display? Where is a good source to learn about using hf_register_info?

From the little information you have given I would consider rewriting the code and add the header information elements with proto_tree_add_item() with Hf_header_version and the appropriate length of the field.
