StringRegExp - numbers w/o letters in pattern

Recommended Posts

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)

By using \b to request word boundary before and after \d+ you can get what I believe you're after.

#include <array.au3>

$aArray = StringRegExp('Java 3009 Update 1a21', '(?i)Java (\b\d+\b) Update (\b\d+\b)', $STR_REGEXPARRAYGLOBALMATCH)
_ArrayDisplay($aArray)

$aArray = StringRegExp('Java 3z09 Update 1a21', '(?i)Java (\b\d+\b) Update (\b\d+\b)', $STR_REGEXPARRAYGLOBALMATCH)
_ArrayDisplay($aArray)

$aArray = StringRegExp('Java 3009 Update 1521', '(?i)Java (\b\d+\b) Update (\b\d+\b)', $STR_REGEXPARRAYGLOBALMATCH)
_ArrayDisplay($aArray)

Note nevertheless that \b relies on the PCRE definition of "word characters", i.e. [0-9A-Za-z_] where the underscore IS a word letter.

      #include <IE.au3> $oIE = _IEAttach ("Edu.corner") Local $aName = "Student name & Code:", $iaName = "0" Local $oTds = _IETagNameGetCollection($oIE, "td") For $oTd In $oTds If $oTd.InnerText = $aName Then $iaName = $oTd.NextElementSibling.InnerText $iGet = StringRegExpReplace($iaName, "\D", "") EndIf Next MsgBox(0, "", $iGet) it was get number like 52503058
      But, I want to get only student code 5250. (Different student have different code, sometime its 3 digits, Sometime 4)

      Is there a way to output the regex matches into a file?
      I have a script to compare two files and check for regex matches.
      I want to output the matching regex of 'testexample.txt' to another file.
      #include <MsgBoxConstants.au3> #include <Array.au3> $Read = FileReadToArray("C:\Users\admin\Documents\testexample.txt") $Dictionary = FileReadToArray("C:\Users\admin\Documents\example.txt") For $p = 0 To UBound($Dictionary) - 1 Step 1 $pattern = $Dictionary[$p] For $i = 0 To UBound($Read) - 1 Step 1 $regex = $Read[$i] If StringRegExp($regex, $pattern, 0) Then MsgBox(0, "ResultsPass", "The string is in the file, highlighted strings: " ) Else MsgBox(0, "ResultsFail", "The string isn't in the file.") EndIf Next Next

      So I have this pattern: 
      ^(?:(\d+)|(\d+):(\d+)|(\d+):(\d+):(\d+))$ And I'm expecting (depending on input) to get a 1, 2 or 3 index array (or @error for invalid input).
      But instead I get this:
      #include <Debug.au3> Func Test($String) _DebugArrayDisplay(StringRegExp($String, '^(?:(\d+)|(\d+):(\d+)|(\d+):(\d+):(\d+))$', 1)) EndFunc Test('10') ; Results (normal, expected): ; Row 0|10 Test('10:20') ; Results (extra blank index): ; Row 0| ; Row 1|10 ; Row 2|20 Test('10:20:30') ; Results (three blank indices): ; Row 0| ; Row 1| ; Row 2| ; Row 3|10 ; Row 4|20 ; Row 5|30 Is this normal? Should I just code around it, or is there a better way to do what I'm looking for?
      I also tried reversing my regex, but it was even uglier results:
      #include <Debug.au3> Func Test($String) _DebugArrayDisplay(StringRegExp($String, '^(?:(\d+):(\d+):(\d+))|(\d+):(\d+)|(\d+)$', 1)) EndFunc Test('10') ; Results (yuck): ; Row 0| ; Row 1| ; Row 2| ; Row 3| ; Row 4| ; Row 5|10 Test('10:20') ; Results (slightly better): ; Row 0| ; Row 1| ; Row 2| ; Row 3|10 ; Row 4|20 Test('10:20:30') ; Results (nice): ; Row 0|10 ; Row 1|20 ; Row 2|30

      Hi,
      I want to add any needed conditions to the StringRegExp command so it can pull out only  "File.au3", "WinAPIFiles.au3", "Test.bmp" into the array
      #include <FileConstants.au3> #include <MsgBoxConstants.au3> #include 'WinAPIFiles.au3' #include "File.au3" ; Script Start - Add your code below here Local $bFileInstall = False ; Change to True and ammend the file paths accordingly. ; This will install the file C:\Test.bmp to the script location. If $bFileInstall Then FileInstall("C:\Test.bmp", @ScriptDir & "\Test.bmp") $sFile = FileRead(@ScriptFullPath) $aResults = StringRegExp($sFile, "(?i)(FileInstall\s*|include\s*)(.*)", 3) _ArrayDisplay($aResults) Thanks In Advance
