正则表达式与多行字符串

Question

I'm trying to make regex for getting diff for each file from project path diff file. Here it is:

--- Training/main/1/a   (revision 18 06 2013 06:48)
+++ Training/main/1/a   (revision 18 06 2013 06:48)
@@ -1,1 +0,0 @@
-isdfsdfsdsadasdasd
\ No newline at end of file
--- Training/main/1/abc (revision After)
+++ Training/main/1/abc (revision After)
@@ -0,0 +1,1 @@
+isdfsdfsdsadasdasd
\ No newline at end of file
--- Training/main/1/test.txt    (revision 18 06 2013 06:48)
+++ Training/main/1/test.txt    (revision After)
@@ -1,1 +1,3 @@
-sfaa
\ No newline at end of file
+sfaaasdasssssdsadasdas
+
+test with moving files on depot
\ No newline at end of file

How to create regex pattern to match each file's diff? For example to match:

Diff 1:

--- Training/main/1/a   (revision 18 06 2013 06:48)
+++ Training/main/1/a   (revision 18 06 2013 06:48)
@@ -1,1 +0,0 @@
-isdfsdfsdsadasdasd
\ No newline at end of file

Diff 2:

--- Training/main/1/abc (revision After)
+++ Training/main/1/abc (revision After)
@@ -0,0 +1,1 @@
+isdfsdfsdsadasdasd
\ No newline at end of file

Answer 1

If possible at all, can you generate the diffs separately? If you have access to the repository this should be the simplest solution.

Otherwise, you cannot do it via regex - any line can start with --- or +++ . The correct solution for splitting the changes is to actually parse the diff format and skip the indicated number of + , - lines and possible other indicators for each file chunk.
