• Regular expression help please. (extraction of a subset of the string between two markers)

  I haven't used regular expressions before, and I can't find a regular expression to extract a subset of the string between two markers.

  The chain;

  Stuff of header I want
  Stuff of header I want
  Stuff of header I want

  Stuff of header I want

  6 ERRORS
                       
  Info I want to line 1
  Info I want line 2
  Info I want line 3
  Info I want to line 4
  Info I want to line 5
  Info I want line 6
  END_ERRORS

  From the string above (it is read from a text file), I try to extract the subset of string between ERRORS 6 and END_ERRORS. The number of errors (6 in this case) can be any number from 1 to 32, and the number of lines I want to extract will correspond with this number. I can provide this number of a caller VI if necessary.

  My current solution, which works, but is not very elegant;

  (1) using Match Regular Expression for the return of the string after you have synchronized the 6 ERRORS

  (2) uses the Regular Expression matches to return all characters before game END_ERRORS of the string returned by (1)

  Is there a way this can be accomplished using 1 Regular Expression Match? If so someone could suggest how, as well as an explanation of the work of the given regular expression.

  Thank you very much

  I used a character class to catch any word or whitespace characters.  This put inside parentheses a substring matching the criteria that you can get by developing the node for regular expression matching.  The \d matches the numbers and the two * s repetition of the previous term.  So, \d* will find the '6', as well as "123456".

• Avoid writing empty lines or remove the empty string between data lines

  Hello

  I have this problem...  I write as a 4 x 4 witch table comes from a graph of intensity in a file. But when I write, regardless of the method that I use out it somehow unusable when I try to read more later.

  Right now I got change for a 1 x 16 table witch I later convert back to 4 x 4 again shown in the graph of the intensity.

  The problem is that I have empty lines between the data I want to remove to display correctly.

  Maybe to be clear in my explanation I will post screenshots of how I write and how I like to read...

  

  Can someone help me?

  Thank you!

  Antonio

  Why do you use a loop to create a string to write to the file? In LabVIEW 8.x writing on a spreadsheet file is polymorphic, so you can select the instance of 'Double' and simply connect your table 2D directly to it, without a loop or anything like that. On playback, even select the instance 'Double' for your return values exactly as you wrote them.

• get the string between {}

  IN the string I want to take all values between {and}.

  This is the string.

  Here's a way to do what you asked (which may or may not be what you need), using REGEXP_REPLACE to remove everything that is not between two brands of {}:

  with t as

  (select ' ({Location1} # equal (12) < and=""> {Item1} # more than # (8) < and=""> {Item2} # # (40) < and=""> {DOCDATE} # between # "January 10, 2015" AND 'January 10, 2017' < and=""> {amount} # equal # 1)' txt)

  the double)

  Select regexp_replace (regexp_replace (regexp_replace(txt,'}[^}]*{','',1,0),'^ [^ {}] * {', ", 1,0}) {,'}. * $',", 1.0)

• Get the string between two operators <>

  Hello
  
  I have a string that looks like this "text here < emplid > more text here '." Now, I want to choose the data between the < and >. These data is still a number. I tried the following query, but it does not give good results.

  select SUBSTRING(NAME,CHARINDEX('<',NAME),CHARINDEX('>',[NAME])) as col01

  This will result in the number, including the < and > (which I'm not) and some characters more. I also need the rest of the chain to be available to insert in another field.

• difference of initial value of string between the steps in the process and an external instance of LabWindows/CVI

  Hello

  I'm curious to know what I see using TestStand, LabWindows/2013 2013 with regard to initial in TestStand string values when you perform the steps in the process or an external instance of LabWindows/CVI.

  I have a step (CVI) string value that is used to check an array of characters stored in an EEPROM to test.  I pass on the Step.Result.String in the CVI by reference.  I then read the table charater of the EEPROM in the chain (Step.Result.String).  The string is then compared against the limit as specified in the test step breast.

  When I run this test step to perform the steps in the process selected in the popup Configuration of the adapter of LabWindows/CVI, it seems that the memory allocated for the string is filled with null characters.  Which is what I expected.

  When I run this test step to execute the steps in an external instance of LabWindows/CVI iselected of the Configuration of the adapter of LabWindows/CVI popup, it seems that the memory allocated for the string is filled with something else.  That is not what I expected.  For example what I see in the memory, it's the first characher is one byte NULL but the remaining bytes are some other values, as shown below:

  F0 00 AD BA 0D F0 AD BA 0D F0 AD BA 0D AD BA 0D AD BA 0D BA 0D AD F0 F0 F0
  F0 AD BA 0D F0 AD BA 0D F0 AD BA 0D F0 AD 0D AD BA 0D AD BA 0D F0 F0 F0 BA...

  In my code I make sure to write a null character in the following location table charater I just write in the chain so I have no problem with the test is working properly.  I have remove the writing from my code null character and was able to verity that the test passes when executing the steps in the process and fails during execution of the steps in an external instance of LabWindows/CVI.

  The returned string contains what I wrote for her, and then the rest of the string is filled with the values that are in the memory allocated for the string.

  Here's my Question: is this the expected behavior for the original string values in TestStand between both types of stage performances?

  Thank you

  Chris Young

  In general teststand not Initializes the unused portion of the string buffer, so it is expected that the values of the memory after character no endpoint will be different, or even to each call. If you happen to be get zeros after the null terminator which was probably due to random character (i.e. the memory allocated just arrived already having zeros in there) or perhaps a debug setting you use perhaps in the Visual C runtime (if you are debugging the process in visual studio or modify visual C runtime heap parameter). TestStand is not initializaing memory after the null terminator character in both cases (I checked the code).

• Read the string between two characters

  I have an xml file that is saved to a text file, and the XML was not in Labview. I want to be able to read each line of the text file and display the text that is between ' > '.

• Find a joint letter between two strings

  Hello

  I need help to find a common string between strings that results in a table. Here's an example scenario that you can consult to replicate and suggest.

  create the table test_marine

  P_ID varchar2 (50).

  t_id varchar2 (50).

  h_code varchar2 (40),

  number of misc_type

  );

  insert into test_m values('1','100','ABC',1);

  insert into test_m values('1','101','ABCD',1);

  insert into test_m values('1','102','BC',1);

  insert into test_m values('1','103','B',1);

  COMMIT;

  Data will look like below: -.

  

  What I have to do here is - I want to take the all the h_code column values across both where p_id = 1 and browse all the values H_CODE one by one. Any other approach viable also who can help will be good.

  Example - I choose ABC for 100, I check if A is common throughout 101,102,103, if so, save somewhere check then if B exists in all.

  My Final result should be like this: -.

  

  Where there is more than one match: -.

  

  Where there is no match, the value may come as something as below: -.

  

  Appreciate the help. Thank you

• Regular expression for middle of string

  Little background. I get the data (only the numbers) and text (can contain numbers) series. Since I don't know which I get and when it starts / ends, I do the sender send 'textSTART ###textSTOP' where ' # ' is what I want to extract. # can contain text, numbers, new line, carriage return or whatever.

  The same for the data : "dataSTART ###dataSTOP", where # contains only numbers.

  I think I should use the match pattern, but I don't know how to make my regular expression.

  Any help is appreciated.

• Parsing HTML in strings from to and input XML

  That's it - sort of... It restores to correctly in my field of dynamic text, in any case, but with two strange things:

  (1) the focal point for the link is not only within the area occupied by the related underlined words, it seems that the length of the expression of a hypertext link, the larger the area below all the way to the lower limit of the dynamic text field.

  (2) - I'll post this in a new thread - link works fine and dandy in a trial within Flash. but, as soon as it is embedded in HTML and read in a browser, the link does nothing. I can click forever, but, alas, my link does not open.

• An empty array to a worksheet string, delimiter

  The string table worksheet function does not accept an empty delimiter, it uses the tab character in such a case.

  The same is true for string array spreadsheet function (but of course this function can not work without a delimiter).

  I would appreciate one of the following options:

  • to allow a blank separator for the two functions (for string in array of spreadsheet that can easily obviously works for the worksheet to an array of strings, you might see a delimiter of empty string between each two adjacent characters similar to the function search and the string to replace with an empty search string);
  • to document this behavior correctly;

  I prefer the first espacially option for the string table worksheet function. What do you think?

  Hi you can use the indexof and substring in this case methods indexof method takes on the character and returns the index of the provided character, now give your characters required to indexof() alternately and get these indexes, now use the substring (startingIndex, endingIndex) for your required string.
