Hello monks, I have a problem with data i am trying to retrieve from a text file.

The contents of files looks like below with the data i require in a table.
The text before and after the table is just general information but varies from file to file that i read, there can be other tables after the one i am tring to read but this must be ignored.
I feel the only way to get this data is to search for words 'Bus Timetable' as this not repeated any where else in the files. But to get the data i require, i need to look at the forth line from 'Bus Timetable'. I then need to some how get the FROM DEPT TO & ARR in the order they are in table, in the following way- FROMDEPT:TOARR ( i.e. twn0900:apt0911 ). I think to stop retrieving the data it can stop when it sees the next + as this is on the last line of the table. 


---TEXT BEFORE---


+---------------+
| Bus Timetable |
+---------------+----+------------+-----------+------+
| BUS SERVICE DAY tm | FROM  DEPT | TO    ARR | 24/7 |
+--------------------+------------+-----------+------+
| C4  metro   mon 15 | twn   0900 | Apt  1011 | yes  |
| C6  intl    mon 45 | LDN   1000 | XTR  1426 | no   |
| B2  susx    mon 20 | cly   1034 | btn  1118 | no   |
| A0  xxxxx   xxx xx | xxx   xxxx | xxx  xxxx | xxx  |
+--------------------+------------+-----------+------+

I have noticed that the file produced can continue the table on the next page but puts the name of table and the headings for the columns as before. So i would like the program to read all tables with 'Bus Timetable' heading but ignore any other tables and text.

So far i have not written any code as i am not sure how to do this as i have been learning perl only 4 weeks now. I think i understand what i want the code to do and that it is possible to do what i have asked. I know how to search for a word but i dont not know how to look a number of lines from the result of search and to look at the table. I guess it should count the number of '|' and get data between the 2 and 4 one?

If any one can help me i will be very thankful

Thank you all so much, Kwun Chang.
