Replace

[Former Member]

Hi everybody.

I have to do a replace using a regular expression to do this:

For example in a XML string, clear al the occurrences of the string like this:

I want to delete all this occurrence.

<field>0000-00-00</field>

I employ a replace like this:

DATA: reg_exp type string.

reg_exp = '<>0000-00-00</>'.

REPLACE ALL OCURRENCES OF REGEX reg_exp IN XML_STRING with ''.

It return me a sy-subrc = 4.

I don't know how to delete all this substring, or witch reg_exp pattern should i employ.

Anybody can help me??

replace them with SPACE or ' '. not ''.

AFTER that do:

condense XML_STRING.

Hi Miguel,

Look at this sample code with output.

DATA: T(10) VALUE 'abcdefghij',

STRING LIKE T,

STR1(4) VALUE 'cdef',

STR2(4) VALUE 'klmn',

STR3(2) VALUE 'kl',

STR4(6) VALUE 'klmnop',

LEN TYPE I VALUE 2.

STRING = T.

WRITE STRING.

REPLACE STR1 WITH STR2 INTO STRING.

WRITE / STRING.

STRING = T.

REPLACE STR1 WITH STR2 INTO STRING LENGTH LEN.

WRITE / STRING.

STRING = T.

REPLACE STR1 WITH STR3 INTO STRING.

WRITE / STRING.

STRING = T.

REPLACE STR1 WITH STR4 INTO STRING.

WRITE / STRING.

The output appears as follows:

abcdefghij

abklmnghij

abklmnefgh

abklghij

abklmnopgh

Note how, in the last line, the field STRING is truncated on the right. The search pattern 'cdef' of length 4 is replaced by 'klmnop' of length 6. Then, the rest of the field STRING is filled up to the end of the field.
