RegExp help desired

3 posts in this topic

Hello altogether,

yes I already noticed the  StringRegExp AutoIt reference  and the very good german tutorial of SEuBo, but nevertheless I would be pleased to get a tip.

I have strings like this:

'repair car "do it your self" check' 

or

' repair car toyota'.

There could be none, one or more words in quotation marks. It could be also that no expression is set in quotation marks (-->" "). The words of the string vary. I would like to generate an array like [repair, car, do it your self, check] or [repair, car, toyota]. Expressions in quotation marks (" ") should not be splitted.

Probably I could use string split and similar methods to combine the words in quotation marks afterwards. But that's not the way I'd like to do it.

I already got this reg-exp to extract just the complete expressions in quotation marks (" ") to seperate these from the rest of the terms:

Local $aExtract4 = StringRegExp($sTest4, '.*?"(.*?)".*?',3)

Moreover I found this reg-exp to work similar to StringSplit with a " " as a delimiter. This would probably a solution if I didn't like to keep the terms in quotations marks together.... :

Local $aExtract8 = StringRegExp($sTest4, '(.+?(?:\s|\z))',3)

Nevertheless I failed to find a single reg-exp that is able to met both conditions. I am convincend that it is possible to design a single reg-exp that met both conditions! I already tried different scenarios with operators like or |, the conditional (?(?=   ) clause and the use of assertion (Lookahead / -behind) but without success.

I would appreciate a hint from an "reg-exp expert" if it's able to solve my problem with a single reg-exp and / or to give me some hints how to do that.

Many thanks in advance.

Try this.

#include <Array.au3>

Local $sTest4 = 'repair car "do it your self" check' & @CRLF & _
        'repair car toyota'& @CRLF & _
        "Repair 'Another Car' sometime"

Local $aExtract4 = StringRegExp($sTest4, '\w+|[''"](.*?)[''"]', 3)

_ArrayDisplay($aExtract4)

Thanks!  Your reg-exp term works perfectly in every case I tested and is shorter and less complicated than my terms...

      Well the plan is to use the power of regular expressions engine of AutoIT for patching binary data.
      Something like this: StringRegExp( $BinaryData,  "(?s)\x55\x8B.."
       
      <cut> ... Okay straight to question/problem
      ... certain bytes that are in the range from 0x80 to 0xA0 won't match.
      Hmm seem to be a char encoding problem. In detail these are 27 chars: 0x80, 0x82~8C, 0x8E, 0x91~9C, 0x9E,0x9F
      Here's a small code snippet to explore / explain this problem:
      #include "StringConstants.au3" $TestData = BinaryToString("0x7E7F808182") ;Okay $match = StringRegExp( $TestData ,'\x7E' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Okay $match = StringRegExp( $TestData ,'\x7F' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Error no match $match = StringRegExp( $TestData ,'\x80' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Okay $match = StringRegExp( $TestData ,'\x81' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;Error no match $match = StringRegExp( $TestData ,'\x82' ,$STR_REGEXPARRAYFULLMATCH) ConsoleWrite('@extended = ' & @extended & ' $match = ' & $match & @CRLF) ;~ output: ;~ @extended = 2 $match = ;~ @extended = 3 $match = ;~ @extended = 0 $match = 1 ;~ @extended = 5 $match = ;~ @extended = 0 $match = 1 Hmm what to do? Go back and use the 'numberstring monster' implementation or just omit that range of 'unsafe bytes'. What is the root of this problem?
      Any idea how to fix this?
       
      Update: Okay I know a byte is not a character.
      But StringRegExp operates on String and so character level.
      Okay as long as you stay at Ansi encoding and only use /x00 - /X7F in the search pattern using  StringRegExp works well to search for binary data.
      What bytes can be matched that are in the range from /X7F - /xFF is also depending on the code page.
      So this avoid to search for bytes in the range from 0x80-0xa0 only applies to Germany.
      I just change this country setting:

      to Thai and now near all bytes from /X7F - /xFF fails to match.

      Hello,
      I have spent the past day fooling with StringRegExp to no avail attempting to get what would be a simple solution to an issue using StringRegExp.
      I will post the code in a sec. The string 'Java x Update y' where x and y are numeric values ONLY if a letter is mixed in anywhere then it should fail. I have been able to successfully deal with the x value so if x = 1234 or a1234 or 1a234 or 1234a would result in a fail if 'a' was in the string. However, when y = 1a234 then I get an output of 1 and when y = 1234a then the output = 1234 when both should fail. I am probably overlooking something simple and in looking through all the material and experimenting I am unable to figure it out and my experience with stringregexp and trying to find examples of this proved difficult. If someone could assist or point me to a thread ? Here is my code ; prob a simple fix. I am also trying to avoid white spaces.
      Thanks in advance
      #include <array.au3> $aArray = StringRegExp('Java 3009 Update 1a21', '(?i)Java (\d+) Update (\d+)', $STR_REGEXPARRAYGLOBALMATCH) If @error Then Exit _ArrayDisplay($aArray)

      Does anyone know how to split a string using multiple delimiters, returning both the values and delimiters withing the Array using StringRegExp?  For example:
      ;~ Split on " Not ", " And ", " Or " $sString = ' Not $a = 1 And $b = 2 Or $b = 3' $aArray = StringRegExp($sString,...) ;~ Returned Results $aArray[0] = '$a = 1' $aArray[1] = 'And' $aArray[2] = '$b = 2' $aArray[3] = 'Or' $aArray[4] = '$b = 3' At the moment I'm using
      Local $aArray1 = StringRegExp($sString, '(?i) Or | And | Not ', 3) Creating a new array using string split and then joining the two arrays together again
      Local $aArray1 = StringSplit(StringRegExpReplace($sString, '(?i) Or | And | Not ', '******'), '******', 3) Unfortunately regular expression isn't my forte.
