stringregexp

[iahngy]

Hi there,

for stringregexp , what should the pattern be for this string to search for the first plus sign ( some of spaces before + )

$str = " +---"

I tried (?=\s*)[\+]*\b

I remembered it works at begining but then when i turn back to try again it doesnt work anymore...Would you give me a correct pattern.

Use the autoit tags to post script code

#include <Array.au3>

$str = "      +---"
$aRet = StringRegExp( $str, "(?<= )([+])", 3 );(?=\s*)[\+] or \s\+
_ArrayDisplay( $aRet )

In your case the b is causing the problem because - is not a word boundary

rather you could use s+ as a simplified pattern

PhoenixXL, what if i want to search a sub string at the end of a sentence like this below...I wnt to extract 20 to get the number that i need for a calculation ...what the pattern should be?

5.0000nS 10.000nS 15.000nS 20.000nS

Simple Stepwise approach

Local $String = "5.0000nS 10.000nS 15.000nS 20.000nS"
$String = StringRegExpReplace( $String, '[^\d.\h]', '' ) ;Replace the Non-Digits exculding the periods and space
$String = StringRegExpReplace( $String, '(\.\d+)', '' ) ;Replace the decimal digits

MsgBox(0, 'Formatted String', $String )
;Now two methods
;.....First
Local $iString = StringRegExp( $String, '\d+$', 3 )
$iString = $iString[0]
MsgBox( 64, 'Result', $iString )

;....Second
;Get the last number
MsgBox( 64, "Result", StringRegExpReplace( $String, '([.\d]+\D+)(?!$)', '' ) );Vice-versa of the First Method

Direct Approach

Local $String = "5.0000nS 10.000nS 15.000nS 20.000nS"

;Get the last number
MsgBox( 64, "Result", StringRegExpReplace( $String, '.*[^.\d](\d+).+', '\1' ) );.* - match everything give back as needed
;[^.\d]- match anything that is not a digit or a period such that it is followed by
;(\d+) - [capturing group] at least one digit
;.+ - match everything left over

;\1 - Return only the digits matched

;Get the last number
MsgBox( 64, "Result", StringRegExpReplace( $String, '([.\d]+\D+)(?!$)', '' ) )

PhoenixXL,

the code above, (?!$) .....is hard to understand and the whole thing together...does (?!$) mean look for the digit following non digit (space) of which suffix is not the end of the string ...( the end or $ is the number 20 ? )...

$s = 2.73
$a = stringregexp($s, "\d\.\d\d", 4)
for $i = 0 to ubound($a) - 1
$b = $a[$i]
consolewrite($b[0] &$b[1] &$b[2] &$b[3]
next

PhoenixXL,

Another problem, for ex, I have a float : 2.73

I wnt to split it into 4 parts such as 2, . , 7, 3

if I use stringregexp, what the pattern should be?

mine is d.dd ...and option 4 ...it wont work .

#include
#include
$s = 2.73
$a = StringRegExp($s, ".", 3)
ConsoleWrite(@error & @CRLF)
ConsoleWrite(_ArrayToString($a, '|') & @CRLF)

[kylomas]

Or simply (non-regexp)

#include <array.au3>

$s = 2.73
$a = Stringsplit($s, '',2)
_arraydisplay($a)

Thank you both..Xeno, Interesting that just one dot it can separate into 4 parts.

Kylomas,

I should research more on stringsplit

[iahngy]

now i understand why just one dot...means only take 1 of whatever ..I thought i hve to use () so it remember the group

A $ is an assertion of a EOF

(?!$) - stands for anything not followed by End of File

But i feel as per your simple aim string operations would be a much faster and easier

Hi,

How can i make a pattern to exclude all chars except the char c or C

for ex,

$s = 'DX990Q_-5C_combo_whatever_uo_abc_8_1x (maybe x is here but sometimes diff char depends on the user)
$pattern = '_[-5910]{1,3}[^\D86]'

I just want to look for -5C or sometimes 95C or 100C or just 5 or 95 or 100 ...not 1x or 8

I put ^D to exclude all chars but how can i add something to get c or C

I think i got it with this simple pattern to look for hot and cold, _-5[cC]?|_100[cC]?

but if 100c or 100C is written 100t, it still take it

Hope this helps

#include <Array.au3>

Local $String = "apartID124_BGA_100C_test1_testfreq_testvolt_ratio32_10x||...-200K//200op?>< 100F"
Local $Match_Array = StringRegExp( $String, "(?i)-?\d+[kfc]", 3 )
_ArrayDisplay( $Match_Array )

Temperatures would most probably be in Kelvin, Fahrenheit or Celsius

This regex will even support negative temperatures with the symbol

Regards
