lua code help

[Martin555 21]

Hi I have data in HEX format it is a long string of numbers and letters. It still start with 5C75303030 and ends
with numbers or letters. I would like to to save the last 6 values after value 5C75303030 in the table, or if is some
value after 5C75303030.
How I can do it?

String is for example:

5B22 AA557FC0 5C7530303031868C 5C7530303045F6 5C7530303030 5C7530303046 5C7530303031 5C75303030357B 5C7530303030 5C7530303132 5C7530303030 5C7530303031F1 5C7530303030 5C7530303033 5C753030303050 5C7530303030FD 5C75303030306D 5C753030303064

So I will try it. But there is a problem. It's not that.  That string still starts with 5C303030 but has different lengths .

that's the result:

"31868","45B85","465C7","35405","305C7","305C7","30505","304E5","30645","30385","335C7","305C7","305C7","305C7","315C7","305C7"........................

 

1 is ok, 2 is ok 3 is not Ok it has value 5c7 etc...

 

After the assignment, I received these results, where in the result there is also 5C7... Wouldn't it be better to find 5C in a string and save 4 values to a table before value 5C? It sends the values after 5C75303030 and selects the values to the next 5C. wouldn't that be better? Is there a command for this?

Eh, I don't think I understand. The code I posted solved your example in the first post. 

Can you give a new example with input string and wanted output table?

This is string code for eample:

5B22AA557FC05C7530303031868C5C7530303045F65C75303030305C75303030465C75303030315C75303030357B5C75303030305C75303031325C75303030305C7530303031F15C75303030305C75303030335C7530303030505C7530303030FD5C75303030306D5C7530303030645C7530303030645C75303030305C225C75303030305C225F5C7530303033

 

I need value underlined. so example  5C7530303031868C  I need 868C  for example 5C73030305C22  I need 5C22,    for example 5C7530303033 I need 33.  for example 5C7530303031EB I need EB

 

It will probably be better to select each part 5C75303030XXX in the table at the beginning and then solve each position separately with the gsub command
