• RESOLVED: Understand regular expressions in search and replace - use it to replace everything between two comments

• Regular expression breaks script

  I have the following statement of regular expressions in my JSX file:

  var regex = /[^/]*(?=\.[^.]+($|\?))/; // Doesn't work while this does: var regex = /[\u0400-\u04FF]+/;
  

  
  .. .and it breaks execution of my script for unknown reasons. What's not here? I thought the syntax / theRegEx.
  (comment to the statement of regex solves the problem and the script runs normally)

  I tested the regex here:
  RegExr: Learn, build, & Test of RegEx

  .. .on this string: "c:/Users/martin.dahlin/Desktop/Test/lolFile.lol".
  gives me "lolFile" without the quotes.

  xbytor is right, there is really no "regex-standard/compliance. Basic things work quite universally, but there are the specifics of the platform and conventions and you just test & work around them.

  That said, get into your regular expression to Tester online regex and a debugger: JavaScript, Python, PHP, and PCRE gives and error "/ separator unescaped ', i.e. must be ' / [^\/] * (?)» = \. [ ^.] +($|\?)) /". Also the use of the explicit constructor is a tad safer, typos lead more reasonable errors.

  2. but they will drive you crazy?

  Hello

  So, you want only the substrings that are well-formed attribute/value pairs (attribute or value may be missing).  You want to ignore anything in the comments that is not part of a well-formed pair.

  It is not very difficult to get a single well-formed pair.  The problem is that there is no good way to say 'everything that is not part of a well-formed pair '.  One solution is to extract from each pair trained well on a separate line and then re - combine them into a single string by id, like this:

  WITH split_data AS

  (

  SELECT id

  comments

  REGEXP_SUBSTR (comments,

  , '#'      ||  -sign #.

  '[^<]+'  || ="" --="" 1="" or="" more="" of="" any="" characters="" except="">

  '<'      || ="" --=""><>

  '[^>]+'  ||  -1 or several characters any except >

  '>'          -- > sign

  1

  LEVEL

  ) AS well_formed_pair

  LEVEL AS pair_num

  OF regex_test

  ([LEVEL CONNECTION <= regexp_count="" (comments,=""> <> <[^>] + > ')

  AND PRIOR id = id

  AND PRIOR SYS_GUID () IS NOT NULL

  )

  SELECT id

  commented THAT the original

  LISTAGG (well_formed_pair) WITHIN GROUP (ORDER BY pair_num)

  THAT cleaned

  OF split_data

  GROUP BY id, comments

  ORDER BY id

  ;

  The 2nd argument of REGEXP_SUBSTR above is actually the same as the 2nd argument of REGEXP_COUNT.  I wrote one of them in a more detailed form, hoping to make it clear what happens if has been done.  You can write an expression so be it.

  The result is just what you asked:

  Thanks for posting the sample data. You post the results, but the validation of the existing query which I suppose, produced good results. I can't run this query, because it requires the ijs_seminar table and a connection variable that also has no post, but I can just comment on the join and the WHERE clause.

  Is this really the best set of sample data for this question? This problem involves Chr (13) and repeated commas, but I don't see any s CHR (13) or repeated commas in the sample data. In addition, it seems that there are a lot of columns that play no role in this issue and just to make things difficult to read.

  My select statement is

  SELECT acc.hotel_name || '(' || replace(replace(acc.address,chr(13),', '),',,',',') || ')'
  FROM TBL_ACCOMMODATION acc
  inner join ijs_seminar s ON acc.accommodation_id = s.accommodation_id
  where s.seminar_id = :P27_SEMINAR_ID
  

  I have to use the function replace twice. We need to replace the Chr (13) by a comma,.

  As posted, inside REPLACE replaces Chr (13) with a comma and a space which could be important if you then pick up consecutive commas.

  second is the band a comma where there are two commas.

  I don't know much about regular expressions.
  If someone can show me a better way to handle this using the regular expression rather than a heavy means above.

  Assuming you want to replace Chr (13) with just a comma, then an equivalent would be:

  SELECT    acc.hotel_name || '('
                    || REGEXP_REPLACE ( acc.address
                                        , '[,' || CHR (13) || ']{1,2}'
                              , ','
                              )
                  || ')'            AS h
  FROM        tbl_accommodation acc
  INNER JOIN  ijs_seminar       s   ON   acc.accommodation_id = s.accommodation_id
  WHERE s.seminar_id = :P27_SEMINAR_ID
  ;
  

  In the argument to REGEXP_REPLACE 2nd

  [xy]{1,2}
  

  medium 1 to 2 characters of set of x and y. This could be
  x or
  there or it could be 2 characters
  XY or the other way
  YX or it could be the same characters 2
  XX or
  YY

  REGEXP_REPLACE is slower that REPLACE. Even if your original expression is longer, it may be more effective. (Performance may be not a problem in this case.)

• Find and replace - regular expression to help?

  How can I find ' <!-* PAGE footer AREA *-> "and replace it and evething after with my new coding of footer on all my pages.

  The problem is:

  The code in my existing page footer area is not the same on all pages.

  I want to replace it with a new one on all pages

  I watch the operators of regular expressions, not found patern that works...

  Thanks in advence for your help

  The following regular expression is the and everything up, but not including the closing tag:

  [\s\S]+(?=<\/body>)
  

  Use it in the search field and put the comment and the code to the footer in the field replace. Select use regular expression.

  Always make a backup before using a regular expression on many pages.

• Are there reasons why T/B could not support wildcard (* xyzpqr *) or regular expressions in search of content of e-mail?

  When a string of characters, I'm interested, is buried in an e-mail, I would find these emails. It seems that as the code needed to find an email is already in place, it would take very little effort/code/support added to extend the search capabilities of more effectively, as it is available in spreadsheets.

  This particular forum has these capabilities, suggesting that users find useful installation.

  Are there reasons preventing these facilities being added to T/B? I find that the ability would frequently help me in search of my email.

  FiltaQuilla both Expression search/GmailUI provide functionality, specifically the regular expressions.

  FiltaQuilla aims to improve the message filters and has a useful side effect in improving the CTRL + SHIFT + f find. Research of expression increases the QuickFilter bar. Or rather weird global research assistance, but I work around this by using a Saved Search folder, where you use a dialog similar to the message filters and can make use of the enhancements offered by one of these modules.

• Use matching of regular expressions to search for parentheses

  Hi all

  I am currently looking for a particular pattern in a string, I can't display the exact string, but say its something like that.        corresponds to regular_pattern (5000): 0

  I'm also looking for the a different model at the same time, so I have to use the corresponding regular expression and the | function.  I can't understand how to match this model because the regular expression function allows parentheses unless I put them in the legs, and that does not help me for this.

  Any advice?

• Multiline - Regular Expression Match string

  I'm trying to understand the format of a regular expression to pull select off multi-line string lines and fill in these lines as the individual elements of an array of strings using regular expressions to Match. The total length of the multiline string may vary as well as the text in the string. The string can contain letters, numbers and special characters. I've attached an example VI. In the example of VI, I want to only return lines starting by "device #" in the table. The number of lines starting by "device #" can vary, but I want to capture them all.

  Or is there a better functioning to be used instead of the corresponding regular Expression that will give me the desired result?

• regular expression for something that does not have a fixed sequence

  Hello

  Just having a little trouble with a regular expression. I have an input string and I want to find something that is not this string, so

  Input = Hello

  Match = Hello

  Football game? = False

  Entry = Hello1

  Match = Hello

  Football game? = False

  Input = Hello

  Match = goodbye

  Football game? = True

  As I thought that I understood it, to enter as a regular expression in the regular Expression.vi of Match would be ~ (Hello).

  If I understand as well, I can't do this by using the match pattern.

  Maybe you good people can correct me. Thank you!

  and I am interested in the tag method to retry only, I could write a regular expression something like

  Forgive me if I am away from base, but I'm flying blind at the moment (not LV to test what I say).  You can add to the power of a regular expression using submatches or capture groups.  The regular expression you wrote will grab (I think) @gmail.com for the entire game.  Let's say you want to get 'gmail' without a second function call.  You can do the first group of a little dishonest selection by moving the * inside the parentheses.  Then, on the BD pull down on the bottom of the function of regular expression matching to expose a variable number of submatches (both should be in this case).  The first should be 'gmail '.   The second one should be "com."

  In summary, @(\w*)\.) (com: net | org) should give you gmail in the first submatch.  Of course, my Perl is a little rusty and LV cannot apply in the same way.
