Hi,
I am having an issue capturing all the data I need in a
particular
postscript format.
The data information is broken down as follows:
The co-ordinates for the data xxxx (space) yyyy (space) the
letter 'M'
(space) and the data is in the brackets.
The next character after the closing bracket can either a
opening
square bracket ([) an 'S' or an end of line (This
determines that this
is valid data).
There are 3 different data format scenarios.
1. 400 767 M (Data I need to extract) -> suffix
characters [ or S or
eol
2. 400 767 M (data \\( I need to extract \\) with nested
brackets)S
The nested brackets will always be escaped with '\\'
3. 175 3303 M (t)S 188 3303 M (t)S 202 3303 M (p)S etc
which is all
on one line
The coordinates may not be the first characters on the line.
I have had some success with
[0-9]{1,4}\s[0-9]{1,4}\s[M]\s\(.*[^\\](?=\)(\z|S|\[
)) but this doesn't
handle data format 3 as it extracts the whole line rather
than breaking
it down to each data section.
The 2 critical issues I need to address are:
-Handling data format 3, which also include nested brackets
-Ensuring that other unwanted data is not captured that may
be in a
similar format but will not contain one of the 3 suffix
characters
mentioned above.
I am new to regular expressions and this is doing my head in
so your
time is appreciated I you can help me.
Regards
Rick
