Extras
1. ... {RESPECTING|IGNORING} CASE
2. ... REPLACEMENT COUNT rcnt
3. ... REPLACEMENT OFFSET roff
4. ... REPLACEMENT LENGTH rlen
5. ... RESULTS result_tab|result_wa
Effect
These additions modify the statement REPLACE
pattern IN and provide advanced evaluation options. The addition CASE
can be used to specify whether the search is case-sensitive. The additions REPLACEMENT
and RESULTS
can be used to determine the number, position, and length of the string(s) replaced.
Addition 1
... {RESPECTING|IGNORING} CASE
Effect
This addition can be used only when processing strings. It has the same syntax and effect as the associated
addition for searching for a substring in a data object
using the FIND
statement. This addition is not permitted when using an instance of class CL_ABAP_REGEX.
Addition 2
... REPLACEMENT COUNT rcnt
Effect
This addition saves the number of replacements made in data object dobj
to rcnt
. The following can be specified for rcnt
:
-
An existing variable that expects the data type
i
. -
An inline declaration
DATA(var)
. The declared variable has the data typei
.
If no replacements are made, rcnt
is set to 0.
Note
In data objects with a fixed length, the number of replacements made in data object dobj
can be less than the number of occurrences.
Addition 3
... REPLACEMENT OFFSET roff
Effect
This addition saves the offset with respect to data object dobj
at which
the last replacement was made to roff
. The following can be specified for roff
:
-
An existing variable that expects the data type
i
. -
An inline declaration
DATA(var)
. The declared variable has the data typei
.
If no replacement is made, roff
retains its existing value or stays initial.
Notes
-
When
ALL OCCURRENCES
is used,REPLACEMENT OFFSET
generally returns a different value than MATCH OFFSET for theFIND
statement. This is because the position of the last location found can be shifted by previous replacements. -
In data objects of fixed length, the value in
roff
refers to the last replacement within the data object. Occurrences that are shifted by previous replacements in the data object are no longer relevant.
Addition 4
... REPLACEMENT LENGTH rlen
Effect
This addition saves the length of the last substring inserted into dobj
to rlen
. The following can be specified for rlen
:
-
An existing variable that expects the data type
i
. -
An inline declaration
DATA(var)
. The declared variable has the data typei
.
If no replacement is made, rlen
retains its existing value or stays initial.
Note
In data objects with a fixed length, the length of the last string inserted can be shorter than the length of new
if the intermediate result is truncated.
Addition 5
... RESULTS result_tab|result_wa
Effect
If at least one replacement is made, the RESULTS
addition saves the offsets
of the locations at which replacements were made. It also saves the length of the substrings inserted
either in an internal table result_tab
or in a structure result_wa
. The syntax and meaning of the addition are otherwise the same as those for the
addition of the same name for the
FIND
statement. The only difference is that in this case, the data types
for result_tab
and result_wa
must be REPL_RESULT_TAB
and REPL_RESULT, in which there is no SUBMATCHES component. As in FIND
, an
inline declaration DATA(var)
can be specified after RESULTS
.
Example
Pattern-based replacement of all occurrences of the word "know" in the data objects text1
and text2
with "should know that". After the first REPLACE
statement, text1
contains the full text "I should know that you should know
that" and sy-subrc
has the value 0. The data objects cnt
,
off
, and len
have the values 2, 23, and 16. After
the second REPLACE
statement, text2
contains the
truncated text "I should know that" and sy-subrc
has the value 2. The data
objects cnt
, off
, and len
have the values 1, 2, and 16.
DATA: text1 TYPE string,
text2 TYPE c LENGTH 18.
text1 = text2 = 'I know you know'.
REPLACE ALL OCCURRENCES OF 'know' IN
text1 WITH 'should know that'
REPLACEMENT COUNT DATA(cnt)
REPLACEMENT OFFSET DATA(off)
REPLACEMENT LENGTH DATA(len).
REPLACE ALL OCCURRENCES OF 'know' IN
text2 WITH 'should know that'
REPLACEMENT COUNT cnt
REPLACEMENT OFFSET off
REPLACEMENT LENGTH len.
