ABAP: search substring on string

Hi,
is there any ABAP function to validate if a substring appears on a string ?, something like:
- 'world' into 'Hellow worldXX' => TRUE
- 'world' into 'The working..' => FALSE
thanks

Does this help ...
CA (Contains Any):
c1 contains at least one character from the string c2.
If c1 or c2 is of type C, the comparison takes into account the full length of the field, including blanks at the end.
If c1 or c2 is of type STRING and empty, the result of the comparison is always negative.
If the result of the comparison is positive, the system field SY-FDPOS contains the offset of the first character in c1 which is also in c2.
If the result of the comparison is negative, the system field SY-FDPOS contains the length of c1.
The comparison is case-sensitive.
Examples:
'ABCDE' CA 'CY' is true; SY-FDPOS = 2.
'ABCDE' CA 'XY' is false; SY-FDPOS = 5.

Search and replace strings in a file while ignoring substrings

Hi:
I have a java program that searches and replaces strings in a file. It makes a new copy of the file, searches for a string in the copy, replaces the string and renames the new copy to the original file, thereafter deleting the copy.
Now searching for "abcd", for eg works fine, but searching for "Topabcd" and replacing it doesnot work because there is a match for "abcd" in a different search scenario. How can I modify the code such that if "abcd" is already searched and replaced then it should not be searched for again or rather search for "abcd" as entire string and not if its a substring of another string.
In the below code output, all instances of "abcd" and the ones of "Topabcd" are replaced by ABCDEFG and TopABCDEF respectively, whereas according to the desired output, "abcd" should be replaced by ABCDEFG and "Topabcd" should be replaced by REPLACEMEFIRST.
try
          String find_productstring = "abcd";
          String replacement_productstring = "ABCDEFG";
          compsXml = new FileReader(compsLoc);
          compsConfigFile = new BufferedReader(compsXml);
          File compsFile =new File("file.xml");
          File compsNewFile =new File("file1.xml");

          while ((compsLine = compsConfigFile.readLine()) != null)
                new_compsLine =compsLine.replaceFirst(find_productstring, replacement_productstring);
                out.write(new_compsLine);
                out.write("\n");
            out.close();
            compsConfigFile.close();
            compsFile.delete();
            compsNewFile.renameTo(compsFile);
        catch (IOException e)
        //since "Topabcd" contains "abcd", which is the search above and hence the string "Topabcd" is not replaced correctly

How to search for particular string in array?

I am struggling to figure out how to search array contents for a string and then delete the entry from the array if it is found.
The code for a program that allows the user to enter up to 20 inventory items (tools) is posted below; I apologize in advance for it as I am also not having much success grasping the concept of OOP and I am certain it is does not conform although it all compiles.
Anyway, if you can provide some assistance as to how to go about searching the array I would be most grateful. Many thanks in advance..

Ok, so you have an array of Strings. And if the string you are searching for is in the array, you need to remove it from the array.
Is that right?
Can you use an ArrayList<String> instead of a String[ ]?
To find it, you would just do:
for (String item : myArray){
   if (item.equals(searchString){
      // remove the element. Not trivial for arrays, very easy for ArrayList
}Heck, with an arraylist you might be able to do the following:
arrayList.remove(arrayList.indexOf(searchString));[edit]
the above assumes you are using 1.5
uses generics and for each loop
[edit2]
and kinda won't work it you have to use an array since you will need the array index to be able to remove it. See the previous post for that, then set the value in that array index to null.

Search for a string in SAP Script

Hello Experts,
Is there a way to search for a string in all Z SAP scripts, like ABAP source scan?
Regards,
Hari.

Try using function module "READ_FORM" (you will have to write a simple z-program to find all SAPscripts in your system then use this function module to search the SAPScript Forms for a particular string).
All you have to do is supply the "FORM" name and it will return all of the Pages, Paragraphs, and Texts etc....
More specifically, try looping at the "FORM_LINES" internal table result and you will see the SAPScript text there....
Have fun !

How to search a special string in txt file and return it's position in txt file?

How to search a special string in txt file and return it's position in txt file?

I just posted a solution for a similar question here: http://forums.ni.com/ni/board/message?board.id=170&view=by_date_ascending&message.id=362699#M362699
The top portion can search for the location of a string, while the bottom portion is to locate the position of a character. Both can search for a character.
The position of the character within the file is displayed in the indicator(s).

Search and replace string formatting

Hi,
I am trying to do a search and replace formatting of a string.
In the example I am looking for string "PASSED" but it must also start with usbflash and some number + PASSED.
I can't get the format to have a number from 1-99. The number of replacements should add up to 6 in this case. I have tried with \d for any number, and I also tried [1-99].
Solved!
Go to Solution.

Right click on the Search And Replace String function. There is an option to use Regular Expressions. Then give this a try.
EDIT: You will need to set the Replace All input to TRUE.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

Search and Replace String throwing the wrong error message with regexp?

This came up in a LAVA thread, and I'm not sure if there's a bug here or not. When using Search and Replace string, and using a regular expression of [(G[b|i])], LabVIEW throws error -4622, "There is an unmatched parenthesis in a regular expression." There are obviously no unmatched parenthesis in that expression, so it seems to me that the wrong error is being thrown. I'm just not sure if that's a syntactically valid regexp. The problem seems to be with nesting [ ]'s inside ( )'s inside [ ]'s. I've tried a couple of regexp resources on the Web, and one suggests it's valid, while the other seems to think it isn't.

I think your regexp is invalid.
In regexps, brackets are not the same as parentheses. Parens are for grouping, while brackets are for matching one of a class of characters. Brackets can not be nested.
If the regexp is replaced with [G[bi]], there is no error, so it's not a matter of nested brackets. I couldn't find anything on the PCRE man page that forbids nested brackets specifically, but it makes sense.
Your expression "[(G[bi])]", therefore parses as a character class which matches '(', 'G', '[', 'b', or 'i' followed by an unmatched paren, and an unmatched bracket.
I don't believe that's the case. Replace the regexp with [(Gbi)], and the error goes away. So it's not a matter of the '(' being literal, and then encountering a ')' without a matching '('.
daveTW wrote:
what string exactly you want to replace? I think the round braces are not right in this case, since they mark partial matches which are given back by "match regular expression". But you don't want to extract parts of the string, you want to replace them (or delete, with empty <replace string>). So if you leave the outer [( ... )] then your RegEx means all strings with either "Gb" or "Gi".
It's not my regular expression. A poster at LAVA was having problems with one of his (a truly frightening one), and this seemed to be the element that was causing the problem. I'm pretty sure that the originator of the regexp meant to use G(b|i), which seems like a complicated way of matching "Gb" or "Gi", if you ask me.

Search and replace string function

Hello, I am using the "search and replace string" function and it does nt seem to work consistently for me. I am using it in a situation where I am taking an array of strings, converting this into a spreadsheet string then deleting all of the commas. Has anyone experienced the same behavior? I have searched through other posts and found other simular faults but none of the fixes worked for this. I can post the code it needed.
Thanks,
Andrew

I agree that commas are often not desirable, especially if your software should also work in countries where comma is used as a decimal seperator.
Where are the commas coming from? Does (1) each element of the original array have one (or more), do you (2) use comma as seperator if you convert it to a spreadhseet string?
For (1), you might just strip out the comma for each element right in the loop. For case (2) you would simply use a different separator to begin with, of course.
Btw: you are abusing a WHILE loop as a FOR loop, because you have a fixed number of iterations. Please replace it with a FOR loop. If you use a FOR loop, LabVIEW can manage memory much more efficiently, because it can allocate the entire output array before the loop starts. For While loops, the total number of iterations is not known to the compiler. (Of course a real program would also stop the loop if an error occurs. In this case you would need to stay woth the WHILE loop. )
Do you have a simple example how the raw array elements look like. How many commas are there?

How can I search for a string like a partial IP address in the global search

When searching for a string like "10.255." the global search finds messages containing "255" or "10" and both.
This happens no matter whether quotation is used or not.
When quotation is used it probably will match on the given order as well, but beeing in the timezone '+0100' the string "10" is always found first (in the email headers...).
Is there a way to tell the global search not to use '.' or any other character as whitespace?

How do i search for a string in a txt file using java??

Regular expressinos work just fine, especially when
searching for patterns. But they seem to be impying
it's a specific group of characters they're looking
for, and indexOf() is much faster than a regex.If he's reading from a file, the I/O time will likely swamp any performance hit that regex introduces. I think contains() (or indexOf() if he's not on 5.0 yet) is preferable to regex just because it's simpler. (And in the case of contains(), the name makes for a very clear, direct mapping between your intent and the code that realizes it.)

Search a text string to get location

Is there any way to search a text string in a PDF file or a page of PDF file to get the location of this text string, say (x, y, width, height)?
Thanks a lot for your help.

I believe that there is an Assembler command to find text in a document. I think it is DocumentText and you have an attribute called withQuads that will give you 4 points that surround the text that you are looking for.
I am going from memory so I would have a look at the DDX reference that comes with Assembler.

You can't. The commandline parameters for Acrobat and Adobe Reader do not allow any type of commands to be run.

Searching for a string in an excel file and return true if found.

How can I search for a string in an excel file and return true if found, its location and also a value.

The problem with searching an excel file is that it contains a header. It would be easiest if you just read the file into a LabVIEW array and search the array. This way you can also get the index and the value of the location.
