Search and replace with comma

Hello All,
I want some help. Please help me.
I have comma delimited Data. When I’m converting Sting to Array, If two commas exists in between then its displaying “Zero” (because its array propriety ). Instead of that I want to display “NaN” .
Please give me any idea to replace comma to NaN. I tried with Search and Replace but it’s not giving as I expected.

Hello GerdW,
Thanks you so much for your reply.
I thought, instead of replacing trailing comma by NaN adding comma before string is more better (because to many string manipulations) But, it’s taking more execution time.

  • Search and replace with wildcard?

    I always use search and replace with Homesite but I wonder if
    there is a way of using a wildcard? I often want to replace text at
    the beginning and end of variable text. I mean, if I have this:
    <h3>First text</h3>
    <h3>Second text here</h3>
    What I'd like is, using the * as a wildcard, is to use
    something like this:
    Replace <h3>*</h3> with <h2>*</h2>
    Any ideas? Thanks

    Make a backup first, in case this doesn't work (although it should).
    Use this in the Find field:
    countryText = "([^"]*)";
    And this in the Replace field:
    <countryText>$1</countryText>

  • Search and Replace with a picture

    Is it possible to search for a specific text (i.e. :-) ) and replace it with a picture (a smiley) throughout the entire document (all text areas)
    Thanks for any help!

    Ahh found it.
    in the dialog you can put in replace with: ^c

  • Search and replace with relative paths

    On my 4GB site, each page has a relative link to a single

    I search for <img src="Access/images/woCmt.gif"> and an img
    with any number of relative links such as <img

    with nothing, that is delete each one. I've looked at using regular
    expression with * with no success.

    Have you tried: [\.\/]*
    That will match zero or more . or / characters (which are
    special
    Regular Expression characters, so they need to be escaped).

  • Search and replace, with pattern matching using a table

    I need to inspect a data stream and standardise a set of codes. I need to
    1. Match any patterns with a dash character and remove the dash and any following characters, eg BN-S -> BN, BN-SH -> BN, ARG-22 -> ARG, etc.
    2. Make a few specific word for word replacements, eg, PAEDSH -> PAED
    This is easy to hard code but can it be done using a table of regex substitutions? Can anyone give a pointer or link to some example code? The couple of regex replacement examples I've found use regex to locate but hard code substitutions.
    Thanks

    You could store all your patterns in a Map. Then iterate over the map inserting the patterns into a regex.

  • Using a variable in a Powershell search and replace string

    Hi
    a couple of days ago I posted a question about doing a search and replace with wildcards
    Search and repalce with Widcards
    I got a swift and very helpful answer but now I need to build on it.
    In a text file I wanted to replace all the text between two defined words.  the script I got was this
    $text = 'Some Server this bit of text varies Language stuff'
    $text -replace '(.*Server) .+? (Language.*)','$1 it will always say this $2'
    It works great but now I want to replace "it will always say this" with a variable and I can't figure out the correct grammar to make this happen.
    Can anyone help??
    Thanks
    Alex

    Here's one way:
    $replace = 'it will aways say this'if ( $text -match '(.*Server) .+? (Language.*)' )
    { "{0} $Replace {1}" -f $matches[1,2] }
    else { $text }

  • 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.

  • Problem with search and replace

    I'm workin on Windows XP, Dreamwearver 8
    When I do a search and replace in a site, the changes will be
    made correctly, however, the auto date stamp that I'm using on my
    pages will duplicate on random pages and overwrite text This
    doesn't occur on all pages, and isn't connected with the actual
    change I'm making. Has anyone experienced this?

    Ok Gary, but...
    in a SQLWorksheet write:
    ababab
    Now Edit -> Replace search for b , replace with \nb
    Result (the last b is not replaced):
    a
    ba
    bab
    At this point, I want to have my string back on one line: Edit -> Replace search for \n , replace with (nothing here)
    Result: The search text "\n" was not found.
    And to make it work I have to tick the Regular Expressions checkbox (in this case substitute escaped characters is ignored).
    While I agree that "it is good to have a choice", I personally find it confusing: none of the few text editors I use (Linux or OSX) behaves this way.

  • Search given string array and replace with another string array using Regex

    Hi All,
    I want to search the given string array and replace with another string array using regex in java
    for example,
    String news = "If you wish to search for any of these characters, they must be preceded by the character to be interpreted"
    String fromValue[] = {"you", "search", "for", "any"}
    String toValue[] = {"me", "dont search", "never", "trip"}
    so the string "you" needs to be converted to "me" i.e you --> me. Similarly
    you --> me
    search --> don't search
    for --> never
    any --> trip
    I want a SINGLE Regular Expression with search and replaces and returns a SINGLE String after replacing all.
    I don't like to iterate one by one and applying regex for each from and to value. Instead i want to iterate the array and form a SINGLE Regulare expression and use to replace the contents of the Entire String.
    One Single regular expression which matches the pattern and solve the issue.
    the output should be as:
    If me wish to don't search never trip etc...,
    Please help me to resolve this.
    Thanks In Advance,
    Kathir

    As stated, no, it can't be done. But that doesn't mean you have to make a separate pass over the input for each word you want to replace. You can employ a regex that matches any word, then use the lower-level Matcher methods to replace the word or not depending on what was matched. Here's an example: import java.util.*;
    import java.util.regex.*;
    public class Test
      static final List<String> oldWords =
          Arrays.asList("you", "search", "for", "any");
      static final List<String> newWords =
          Arrays.asList("me", "dont search", "never", "trip");
      public static void main(String[] args) throws Exception
        String str = "If you wish to search for any of these characters, "
            + "they must be preceded by the character to be interpreted";
        System.out.println(doReplace(str));
      public static String doReplace(String str)
        Pattern p = Pattern.compile("\\b\\w+\\b");
        Matcher m = p.matcher(str);
        StringBuffer sb = new StringBuffer();
        while (m.find())
          int pos = oldWords.indexOf(m.group());
          if (pos > -1)
            m.appendReplacement(sb, "");
            sb.append(newWords.get(pos));
        m.appendTail(sb);
        return sb.toString();
    } This is just a demonstration of the technique; a real-world solution would require a more complicated regex, and I would probably use a Map instead of the two Lists (or arrays).

  • Search and Replace "Column Break" with "Page Break"?

    I have been using the "column break" where I really should have been using the "page break". The page break just makes more sense in my layout.

  • Search and replace formulas with AppleScript

    Thanks to this forum I've found out that it is possible to search and replace text by other text or formulas with AppleScript in Numbers 3.2
    Does anybody have a script to search and replace a formula or a part of a formula by another formula or a partial formula.
    For example:
    I would like to be able to find:
    = Table1::$b$3
    and replace this by:
    = Table1::$b$4

    De Signature,
    Would this approach work for you...
    This is a very neat way edit a complex formula in a single cell....
    a) Copy and Paste the formula to a new black page in Pages,
    b) Do your Find and Replace, then
    c) Copy and Paste the formulae back into the cell in Numbers.
    It works like a charm.
    Here is an example of how I used this approach...
    Original cell formulae:
    =AVERAGE(
    SMALL(OFFSET(K3,1,0,20,1),1),SMALL(OFFSET(K3,1,0,20,1),2),
    SMALL(OFFSET(K3,1,0,20,1),3),SMALL(OFFSET(K3,1,0,20,1),4),
    SMALL(OFFSET(K3,1,0,20,1),5),SMALL(OFFSET(K3,1,0,20,1),6),
    SMALL(OFFSET(K3,1,0,20,1),7),SMALL(OFFSET(K3,1,0,20,1),8))
    Final version of formulae:
    =AVERAGE(
    SMALL(OFFSET(K3,N1,0,20,1),1),SMALL(OFFSET(K3,N1,0,20,1),2),
    SMALL(OFFSET(K3,N1,0,20,1),3),SMALL(OFFSET(K3,N1,0,20,1),4),
    SMALL(OFFSET(K3,N1,0,20,1),5),SMALL(OFFSET(K3,N1,0,20,1),6),
    SMALL(OFFSET(K3,N1,0,20,1),7),SMALL(OFFSET(K3,N1,0,20,1),8))
    Find Replace: be cautious with the Find, to ensure it is unique, in my this example ",1,", to avoid changing the" ,1)"
    Enjoy...

  • 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?
