Parse File into Database
I need to read a file into a database with the following structure, years ago I learned how to do xml, and csv, but I can't define this file structure, so I'm floundering a little since I'm a bit out of practice.
filename exported_stocklevels.txt
Item_1 = {
stock = true,
on_hand = 0,
back_order = 5,
reorder = 2,
}
Item_2 = {
stock = no,
on_hand = 0,
back_order = 3,
reorder_point = 1,
I know how to update with cfupdate, etc, but I've always struggled with reading in data from files. especially when I can't control the file structure.

Hi,
Looks like you will need to use the 'find' and 'mid' functions to extract each value.
To program the function, just imagine you are controlling a cursor.
Lets assume you open the text file and call it variable txtfile.
E.g
<cfset start = find("stock = ", txtfile, 0)>
Then you count the characters to extract the value.
<cfset end = find(",", txtfile, start + 8)>
<cfset value = mid(txtfile, start, end - start)>
This should get the first value, then you change the start postion to get the next value.
The code example above is a bit rough, I can help you further if you let me know about the reorder value below.
One thing I noticed is the
reorder = 2,
and
reorder_point = 1,
Are these consistent in the datafile or just an error in your example?
Hope this helps.

It was an error in my example.
the format is consistent. I also dropped the closing brace. my bad. thanks for all the replies, will finish looking them over in a little bit.

Thanks guys, I appreciate the quick help.
- What version of CF - 8 or higher?
- Is that the exact format of the data file including new lines?
- Do you need to extract all of the values? If so are those all of the possible keys? (There's differences between item_1 and 2)
