StringRegExp and FormFeed

10 posts in this topic

#1 ·  Posted (edited)

Hello,

I have string (loaded from file) containing many 'pages' each with "Name : ........multiple lines ending in CRLF, then Escape Formfeed".  I want to use StringRegExp to select each page in turn. I started thinking the pattern should be "Name.*ef".  But . does not include rn, so I looked at (?s), now . includes r and n but also includes f which I don't want. How do I build the right selection character set?

Richard.

Where does it say rn contains f?

Edit: I misread the question initially.

(?s) . matches anything including newline. (by default "." don't match newline)

Ah, OK. I missed the (?s)

Can you provide an example of input and output, because I'm sure there is a better way of using a greedy operator.

What's wrong with just using the hex value of the characters you wish to include. Form Feed is "x0C", so Not Form Feed would be "[^x0C]+". I haven't tested it.

using the s option (?s) at the head of the regexp will make dot (.) match newlines as well.

So your pattern could simply be:

(?s).*\f

  $sFileData  = "Name A" & "1" & @CRLF & "2" & @CRLF & "3" & @CRLF & Chr(27) & Chr(12)
  $sFileData &= "Name B" & "1" & @CRLF & "2" & @CRLF & "3" & @CRLF & Chr(27) & Chr(12)
  $sFileData &= "Name C" & "1" & @CRLF & "2" & @CRLF & "3" & @CRLF & Chr(27) & Chr(12)



  $Ary = StringRegExp($sFileData, "Name.*\r\n", 3)
  ;$Ary = StringRegExp($sFileData, "Name.*\f", 3)


  $iNofTags = UBound($Ary)
  For $iTagIx = 0 To $iNofTags - 1
      ConsoleWrite(StringFormat("Tag %d ~%s~\n", $iTagIx, $Ary[$iTagIx]))
      If $iTagIx > 4 Then ExitLoop
  Next

Output

Tag 0 ~Name A1

~

Tag 1 ~Name B1

~

Tag 2 ~Name C1

~

But the output I want is

Tag0 Name A1

2

3

Tag1 NameB1

2

3

Tag2 NameC1

2

3

T

When I use the f or (?s) $Ary is not an array.

This or JCHD's pattern:

#include <Array.au3>
$sFileData  = "Name A" & "1" & @CRLF & "2" & @CRLF & "3" & @CRLF & Chr(27) & Chr(12)
$sFileData &= "Name B" & "1" & @CRLF & "2" & @CRLF & "3" & @CRLF & Chr(27) & Chr(12)
$sFileData &= "Name C" & "1" & @CRLF & "2" & @CRLF & "3" & @CRLF & Chr(27) & Chr(12)

$aArray = StringRegExp($sFileData, "[^\f]+", 3)
_ArrayDisplay($aArray)
