| Guest | Trying to -match across lines of a .txt Hi, I have a .txt file that contains:- CSC120 20/05/08 16:55:39 2376032 OPRDATA: 28 0 4 15 57540 garbage garbage garbage CSC120 20/05/08 16:55:42 2376033 OPRDATA: 68 1 6 15 53218 garbage garbage And so on. I'm trying to find a way to match the entirety of the two lines that begin 'CSC' and 'OPRDATA' but I want a single match for both these lines. I'd like to use a regex for this. I could probably do a 'foreach' with an 'if' to iterate through all the lines, and I could also just grab all the line matches for 'CSC' then all the line matches for 'OPR' then bolt them together - but I want to use a regex as it will be more extensible for other things that I want to do. In the hex view of the .txt I can see an '0D 0A" at the end of the 'CSC' line so I've tried a regex featuring CRLF but can't seem to find a way to get the match to span both lines. Would appreciate any help. Thanks Stuart |

You will need to look at your file as one string: $contents = ( Get-Content file.txt ) | Out-String Once you have that, the regular expression is pretty simple: [regex]::Matches( $contents, "CSC[^\n]*\s+OPRDATA[^\n]*" ) | Foreach-Object { $_.Value } I hope that helps. Jeff | ||||||||||||

| Guest | Re: Trying to -match across lines of a .txt It helps immensely Jeff. I have to keep reminding myself that get-content is returning an 'array of strings', not one big string :-) Thanks for keeping me right, it's doing what I want now. Regards, Stuart |
