 1. Removed the `route` argument from `r3_tree_insert_pathl`:
 
-    node * r3_tree_insert_pathl(node *tree, char *path, int path_len, void * data);
+        node * r3_tree_insert_pathl(node *tree, char *path, int path_len, void * data);

+        r3_tree_insert_path(n, "/user2/{id:\\d+}", &var2);
 
 2. The original `r3_tree_insert_pathl` has been moved to `_r3_tree_insert_pathl` as a private API.
 
 3. Moved `r3_tree_matchl` to `r3_tree_matchl` since it require the length of the path string.
 
-    m = r3_tree_matchl( n , "/foo", strlen("/foo"), entry);
+        m = r3_tree_matchl( n , "/foo", strlen("/foo"), entry);
 
 4. Added `r3_tree_match` for users to match a path without the length of the path string.
 
-    m = r3_tree_match( n , "/foo", entry);
+        m = r3_tree_match( n , "/foo", entry);
 
 5. Added `r3_tree_match_entry` for users want to match a `match_entry`, which is just a macro to simplify the use:
