Regular expression and output format

hi all,
i have following scenario-
regular expression: [0-9]{3}-[0-9]{3}-[0-9]{4}
generated value by the above regular expression: 123-234-6789
output format to display the generated above value: xxx-xxx-$1
now i need to display the generated value (123-234-6789) in the specified output format (xxx-xxx-$1) and the final output will be xxx-xxx-6789
how is it possible?
Note: here regular expression and output format can vary

Hi, Bashar
You can solve this problem by using the Data Masking Technique.
Masking data means replacing certain fields with a Mask character (such as an X). This effectively disguises the data content while preserving the same formatting on front end screens and reports. For example, a column of credit card numbers might look like:
4346 6454 0020 5379
4493 9238 7315 5787
4297 8296 7496 8724
and after the masking operation the information would appear as:
4346 XXXX XXXX 5379
4493 XXXX XXXX 5787
4297 XXXX XXXX 8724
The masking characters effectively remove much of the sensitive content from the record while still preserving the look and feel. Take care to ensure that enough of the data is masked to preserve security.
It would not be hard to regenerate the original credit card number from a masking operation such as: 4297 8296 7496 87XX since the numbers are generated with a specific and well known checksum algorithm.

    I am using Oracle 9i, does 9i support regular expression? What functions are there?
    My problem is the birth_date column in my database comes from teleform ( a scan program that reads what people wrote on paper), so the format is all jacked up.... 50% of them are 01/01/1981, 10% are 5/14/1995, 10% are 12/5/1993, 10% are 1/1/1983, 10% are 24-JUL-98. I have never really used regular expression and pl/sql, can anybody help me convert all of them to 01/01/1998?
    Does Oralce 9i support regular expression? What can I do if oralce 9i does not support regular expression? Thank you very much in advance.

    9i doesn't support regular expressions (at least not in the 10g regular expressions sense. There is an OWA_PATTERN_MATCH package that has some facilities for regular expressions). But it doesn't look like this is a regular expressions problem.
    Instead, this is probably a case where you need to
    - enumerate the format masks you want to try
    - determine the order you want to try them
    - write a small function that tries each format mask in succession until one matches.
    Of course, there is no guarantee that you'll ever be able to convert the data to the date that the user intended because some values will be ambiguous. For example, 01/02/03 could mean Feb 1, 2003 or Jan 2, 2003 or Feb 3, 2001 depending on the person who entered the data.
    Assuming you can define the order, your function would just try each format mask in turn until one generated a valid date, i.e.
    BEGIN
      BEGIN
        l_date := TO_DATE( p_string_value, format_mask_1 );
        RETURN l_date;
      EXCEPTION
        WHEN OTHERS THEN
          NULL;
      END;
      BEGIN
        l_date := TO_DATE( p_string_value, format_mask_2 );
        RETURN l_date;
      EXCEPTION
        WHEN OTHERS THEN
          NULL;
      END;
      BEGIN
        l_date := TO_DATE( p_string_value, format_mask_3 );
        RETURN l_date;
      EXCEPTION
        WHEN OTHERS THEN
          NULL;
      END;
      BEGIN
        l_date := TO_DATE( p_string_value, format_mask_N );
        RETURN l_date;

  • Juniper MX Regular expressions and user permissions ACS 5.4

    Hi everyone!
    Im having some trouble with regular expressions and permissions on our Juniper MX routers through ACS 5.4, and i would like some insight/help/poitners!!
    We have a team of engineers that should only have read only permissions (important: show configuration) and also be able to just change the description on interfaces.
    Thus far with the following regular expressions set for the shell profile they are going through i have managed the above, however the problem is when an engineer inputs "Show configuration", only the interfaces descriptions configuration is shown! The rest of the configuration will not be printed.
    deny-commands1=.*.
    allow-commands1=configure
    deny-configuration1=.*.
    allow-commands2=interfaces .*. description .*$
    allow-configuration1=interfaces .*. description .*$
    allow-commands2=show configuration.*
    allow-commands3=show configuration
    (some of these regex i know that are not needed, i was just playing around to check everything before posting)
    Any pointers as to why or how to resolve this?
    example output with the above:
    show configuration

    You are absolutely right!!  I was doing research online after posting the above.  The correct RADIUS attribute to use is actually CVPN3000/ASA/PIX7.x-Group-Based-Address-Pools.  Then create the pool in ASA, and call that pool's name in ACS under that RADIUS attribute.  Someone explained this perfectly in this community before.  Much appreciate your answer!
    Here's from another post last year:
    ACS  5 does not have the feature of IP pools. Logically its always good to  setup pools locally on vpn server and if you want user to pick ip from  specific local pool you can configure acs to push that attribute.
    On ACS Go to > Policy Elements  -> Network Access ->   Authorization Profiles -> Create ->
    Name of the Policy ->Dictionary Type: Radius-Cisco VPN 3000/ASA/PIX7.x

  • Regular expressions and sql

    I have working regular expressions and a working sql connection, but I don�t know how to stop the info from getting into the database when input doesent match the regular expression.
    For instans, you put in an e-mail without an "@" and my program writes and error message. But the info still gets in to the database.
    Any help would be much apreciated as I dont know where to start. If you have links or code examples that would be great to.
    Thanx.

    Well, the obvious answer is "only write the data to the database if the input doesn't match the regular expression."
    Presumably you're really asking how to do that - but it depends upon how your application is structured in the first place, and you haven't told us anything at all about that.

  • Log in language would be english or german and output format would be in ge

    Hi,

    Regards,

    Hello Ranu,
    How do you call the script ?
    If you are calling using a z* program, then you can set the language aalso with the OPEN_FORM (LANGUAGE) function module. Always pass this as 'DE'. By default, it will take the log-on language.
    If it is standard program and you are assigning the form using some customization, then you may have some option to assign the language aslo.

  • Regular expressions and backreference

    Hello!
    I am trying to use backreferences in REGEXP in the PERL-style, where I want to match my regular expression and later refer to the grouped values. I can read that those are referecenced with \1 .. \9, but I simply cant get it to work. Here is an example in PL/SQL:
    SELECT REGEXP_SUBSTR(l_users.adresse,'([A-Z]+)\s+(\d+)')
    INTO l_dummy_varchar2
    FROM dual;
    OR I could do things like:
    l_dummy_varchar2 := REGEXP_SUBSTR(l_users.adresse,'([A-Z]+)\s+(\d+)');
    It seems to work, but I cant figure out how to get the backreferenced value.
    I would love to do things like:
    dbms_output.put_line('my value ='||\1)
    but this doesnt work.
    Help is very much appreciated.
    Best regards
    Dannie

    Likewise you can extract things using the
    REGEXP_SUBSTR, but you don't need back
    referencing...backreferencing is better than additional function (ltrim) use, and BTW be careful with this "ltrims":

  • Regular expression and XML

    Hello,
    I have an XML file containing regular expressions and i parse the file, extract the pattern from it and search for it using java regex package. The problem is it works fine when patterns are words but when the pattern is something like
    write \\d+ (write followed by a space followed by one or mre digits) it doesn't work.
    I wrote the same code but with the pattern embedded in it,ie. without using XML and it worked. But when extracting with XML it fails.
    Also if the pattern is write[0-9] it only extracts write[0-9 and gives an error of no closing bracket.

  • Find text using regular expression and add highlight annotation

    Hi Friends
                       Is it possible to find text using regular expression and add highlight annotation using plugin

    A plugin can use the PDWordFinder to get a list of the words on a page, and their location. That's all that the API offers for searching. Of course, you can use a regular expression library to work with that word list.

  • "Match Regular Expression" and "Match Pattern" vi's behave differently

    Hi,
    I have a simple string matching need and by experimenting found that the "Match Regular Expression" and "Match Pattern" vi's behave somewhat differently. I'd assume that the regular expression inputs on both would behave the same. A difference I've discovered is that the "|" character (the "vertical bar" character, commonly used as an "or" operator) is recognized as such in the Match Regular Expression vi, but not in the Match Pattern vi (where it is taken literally). Furthermore, I cannot find any documentation in Help (on-line or in LabVIEW) about the "|" character usage in regular expressions. Is this documented anywhere?
    For example, suppose I want to match any of the following 4 words: "The" or "quick" or "brown" or "fox". The regular expression "The|quick|brown|fox" (without the quotes) works for the Match Regular Expression vi but not the Match Pattern vi. Below is a picture of the block diagram and the front panel results:
    The Help says that the Match Regular Expression vi performs somewhat slower than the Match Pattern vi, so I started with the latter. But since it doesn't work for me, I'll use the former. But does anyone have any idea of the speed difference? I'd assume it is negligible in such a simple example.
    Thanks!

    Oh great Oracle Guru can I can gets some help

    myphone ... just null
    (914)-123-1234.. (914) 123-1234
    I really tried to understand the regular expressions statments, but for some reason I just can't understand it.

    Hi,
    Welcome to the forum!
    I would create a user-defined function for this. I expect there will be a lot of exceptions to the regular rules (for example, strings that do not contain exactly 10 digits, such as '1-800-987-6543') that can be handled, but would require lots of nested fucntions and othwer complicted code if you had to do it in a single statement.
    If you really want to do it with a regular expression:
    SELECT     phone_txt
    ,     REGEXP_REPLACE ( phone_txt
                     , '^\D*'          || -- 0 or more non-digits at the beginning of the string
                           '(\d\d\d)'     || -- \1 = 3 consecutive digits
                    '\D*'          || -- 0 or more non-digits
                           '(\d\d\d)'     || -- \2 = 3 consecutive digits
                    '\D*'          || -- 0 or more non-digits
                           '(\d\d\d)'     || -- \3 = 4 consecutive digits
                    '\D*$'             -- 0 or more non-digits at the end of the string

  • Regular Expressions and comments

    Hello,
    I've got a problem with regular expressions. I Want to find special words like "todo" in java comments, but wasn't able to manage that satisfactory. I hope someone of you can give me an advice! :-)
    example of a comment:
    * comment text. todo: what is still todo.
    First of all, I tried this:
    /\*(.*?)todo(.*?)\*/
    but this version seems to ignore the borders of the comment and shows me also parts of the code.
    Then I tried this:
    /\*([^/]*?)todo(.*?)\*/
    this version returns good results, but doesn't notice html formatting like
    * <code> .... </code> text. todo: text
    So my idea now is to check whether a star precedes the slash, but I don't really know how to combine it.
    Or is there another simplier solution? Thanks for your hints!
    Greetz Jan

    Thanks for your answer, but when I take this expression the programm seems to hang-up. An operation that usually finishs in 3 secs didn't even in 10 minutes. :-( Do you have any idea what could be wrong?
    btw. can I take this one:
    pattern = Pattern.compile("/\\*(?:[^\\*]+|\\*(?!/))*todo.*?\\*/", Pattern.DOTALL | Pattern.CASE_INSENSITIVE);
    matcher = pattern.matcher(text);
    text = matcher.replaceAll("");or do I have to take a this instead of replaceAll():
    while (matcher.find()) {
        text = text.substring(0, matcher.start(1)) + text.substring(matcher.end(1), text.length());
        matcher = pattern.matcher(text);
    }any hints?

  • Regular Expressions and Numbers in Strings

    Looking for someone who has had experience in using Regular Expressions in the Classification Rule Builder.
    We have an eVar that is collecting the number of search results in this fashion:
    <Total Results>_<# of Item 1>_<# of Item 2>_<# of Item 3>_<# of Item 4>
    Example output would look like this:
    150_50_0_25_75
    What we've done is initially create a Regular Expression that looks like this:
    ^(.+)\_(.+)\_(.+)\_(.+)\_(.+)$
    The problem is, it appears in situations where the output contains a zero in one of the slots, the value is ignored and it receives the value in the next place over.  Using the example output shown above, I would end up with values like this:
    $0 150_50_0_25_75
    $1 150
    $2 50
    $3 25
    $4 75
    $5 {null}
    Here's the weird part.  When I perform a test of a single record, it appears like it will work just fine, but when it actually runs in Omniture, it's not working as expected.  Here's something else I'd like to know if it's possible to address.  The five-place string is only the newest iteration of this approach.  In the past, we started out with a two-place version, then three-place and then four.  Any recommendations for handling all scenarios?
    Any and all advice is welcome.  Thanks in advance!

    Doing some playing around on rubular.com and thinking the Regular Expression should be build this way instead:
    ^(\d+)\_(\d+)\_(\d+)\_(\d+)\_(\d+)$
    Again, still looking for any additional guidance from more experienced individuals.  Thanks!

    My web application displays lot of texts which are stored in the database. My requirement is to scan each text for the occurance of any of the above keywords. If any keyword is present I have to replace that with some custom values, before showing it to the user.
    I was thinking of using using regular expression for replacing the keyword in the text using matcher.replaceAll method as follows:
    Pattern pattern = Pattern.compile(patternStr);
    Matcher matcher = pattern.matcher(inputStr);
    String output = matcher.replaceAll(replacementStr);
    But My pattern string will have around 5000 keywords with the 'OR' Logical Operator like- keyword1| keyword2 I keyword3 | ..........
    Will such a big pattern string adversly affect the performance? What can I do to speed up the performance? (Since my keyword list is not static i would prefer to do the replacement just before showing the text to the user)
    Any suggestions are most welcome.

    I don't think a pure regex approach would be that slow, but it would be a maintenance nightmare. I think a combined regex/table-lookup approach would be best: use a regex to identify potential keywords, then look them up in the table to confirm. For instance, to find all Java keywords you could use the regex "\\b[a-z]{2,12}+\\b" to filter out anything that can't possibility be a keyword.
    What are you going to replace the keywords with? Will it vary depending on which keyword is found? If so, you'll have to use a table--and you won't be able to use the replaceAll method, because it can't handle dynamically generated replacement values. You would have to use the lower-level appendReplacement and appendTail method instead.
