Search for a string within a text file

[Hadez]

Iam able to search for a string within a text file, but the problem arrises when there is an unknown variable attached to the string im searching for. E.G.

I fileread Log.txt.

I need to search for the string 'Process Error/Cause/xxyyyy' ( where x are unknown letters and y are unknown numbers. 'Process Error/Cause/' is always present before the unknown characters)

This string could be contained anywhere within the txt file so i cant specify a line number to search.

Once the string is found, the string is written in a msgbox

How would i go about searching for this string?

Thanks for any help you can give.

$var = _StringBetween ("Process Error/Cause/","'")
if IsArray ($var) Then
While Not StringInStr(FileRead ("Log.txt"),$var)
Sleep(100)
Wend

dont think i missed anything. im not an expert.

I think that would work if i knew what was before and after the string but unfortunately i dont. the line on the text file could be:

iiiiiiiiiiiiiiiffffff Process Error/Cause/as2455 aaaaaaaassasadasdasdfsasf or

hhhhhhhhhjjjjjjfuf Process Error/Cause/ds1234 dasdasdfaeffvasd or

aadf Process Error/Cause/hj4415 dsdsdasdasd

etc

i put the ' in the first post to show what the string was. '' are not a part of the string. thanks for taking the time ot reply though

$sStr = FileRead("somefullpath.txt")
$aSRE = StringRegExp($sStr, "(/i)(?m:^).+error/cause/(.+)(?:\v|$)+", 3)
If NOT @Error Then
    For $i = 0 To Ubound($aSRE) -1
        MsgBox(0, "Result " & $i+1), $aSRE[$i])
    Next
EndIf

is there always a space behind it?

[Hadez]

not always. there can be absolutely anything before or after it. and GEOSoft, i think im being a numpty but i cudnt get ur code to work. tried to mess around with it but still cudnt get it to work

$nOffset = 1
$sStr = FileRead("C:\Documents and Settings\ST\Desktop\Log.txt")
$aSRE = StringRegExp($sStr,'Process Error/Cause/(.+)(?:\v|$)+', 1, $nOffset)

 ;StringRegExp("test",
If NOT @Error Then
    For $i = 0 To Ubound($aSRE) -1
    msgbox(0, "Process Error/Cause/" & $i, "Process Error/Cause/" & $aSRE[$i])

    Next
EndIf

so far that finds the string im looking for but also has all the end characters to the readline that i dont want. is there any way to trim the string so that only 6 characters are after 'Process Error/Cause/' ? E.g

The line on the text reads 'gggggggggg Process Error/Cause/sd0215 ooooooooooooooooo'

stringregexp gets it to 'sd0215 ooooooooooooooooo'

i only want the sd0215 (sd0215 is a variable) any ideas how to trim it?

You don't need $nOffset. 1 is the default

$aSRE = StringRegExp($sStr,"(?i)Process Error/Cause/([a-z]{2}\d{4}).*(?:\v|$)+", 3)

Edit. Had the expression backwards

You could also try this one

$aSRE = StringRegExp($sStr,"(?i)Process Error/Cause/([a-z]{2}\d+)\D.*(?:\v|$)+", 3)

[Hadez]

$aSRE = StringRegExp($sStr,"(?i)Process Error/Cause/([a-z]{2}\d{4}).*(?:\v|$)+", 3)

This line worked perfectly. Thanks alot GEOSoft
