Searching for a table in table lua - lua

Question

I have a table in a table structure like this:
[1] = {
[1] = {
category = "WORD",
cursor = <filtered>,
ptype = "STATEMENT",
ttype = "SERVICE",
value = "service",
<metatable> = <filtered>
},
[2] = {
category = "VARIABLE",
cursor = <filtered>,
ptype = "STATEMENT",
ttype = "IDENTIFIER",
value = "TestService",
<metatable> = <filtered>
},
[3] = {
ttype = "BRACE_BLOCK",
value = {
[1] = { ...
...
[2] = {
[1] = {
category = "WORD",
cursor = <filtered>,
ptype = "STATEMENT",
ttype = "SERVICE",
value = "service",
<metatable> = <filtered>
},
[2] = {
category = "VARIABLE",
cursor = <filtered>,
ptype = "STATEMENT",
ttype = "IDENTIFIER",
value = "HelloWorld",
<metatable> = <filtered>
},
I programmed a simply loop which looks for the first table with the ttype, filtered that information out and would like to assign the rest of the tokens until the next Service starts to corresponding service. My idea looks like that:
local found_service = 0
if found_service == 0 then
for k1, v1 in pairs (parse_tree) do
for i=1,#v1 do
if v1[i].ttype == "SERVICE" then
--Store wanted data in an object
found_service = 1
end
if (found_service == 1 and v1[i].ttype ~= "SERVICE") then
-- ->assign the rest to last found service
end
if found_service == 1 and v1[i].ttype == "SERVICE" then
-- ->Found the next service -->starting over
found_service = 0
end
end
end
end
The problem is that I stuck at index i, and v1[i] is a "SERVICE", so he enters directly the last if-clause, too. How do I end one loop-iteration (after the first if-clause). Or ist there a much better way to do this?
Thanks in advise.

I'm not sure if I understand your general idea, but here is the answer of how to skip loop body on first "SERVICE" capture event.
local found_service = 0
if found_service == 0 then
for k1, v1 in pairs (parse_tree) do
for i=1,#v1 do
if (found_service == 0 and v1[i].ttype == "SERVICE") then
--Store wanted data in an object
found_service = 1
else
if (found_service == 1 and v1[i].ttype ~= "SERVICE") then
-- ->assign the rest to last found service
end
if found_service == 1 and v1[i].ttype == "SERVICE" then
-- ->Found the next service -->starting over
found_service = 0
end
end
end
end
end
But I'm still don't get it what should be done on current record not "SERVICE" and found_service == 0. By the way, in my answer after found_service become 0 in third if, the first if could be true again.
If your idea is to build some kind of vector like:
SERVICE_1 (other ttype tables until next SERVICE)
SERVICE_2 (other ttype tables until next SERVICE)
...
In that case code could be:
local found_service = 0
if found_service == 0 then
for k1, v1 in pairs (parse_tree) do
for i=1,#v1 do
if (found_service == 0 and v1[i].ttype == "SERVICE") then
--Store wanted data in an object
found_service = 1
current_service = v1[i]
else
if (found_service == 1 and v1[i].ttype ~= "SERVICE") then
-- ->assign the rest to last found service
end
if found_service == 1 and v1[i].ttype == "SERVICE" then
-- ->Found the next service -->starting over
current_service = v1[i]
end
end
end
end
end
