regex global match like Perl m//g John Cook 11.07.2007 05:02:01 How do I use PowerShell to find all matches of a regular expression in a string, analogous to the 'g' option on matches in Perl?

Re: regex global match like Perl m//g "Kiron" <Kiron[ at ]HighPlainsDrifter.com> 11.07.2007 07:14:53 I'm not sure about Perl's 'm//g' output, no Perl experience :( To get all Regex matches in a string you can use .Net's Regex.Matches method: $string = "x1 c4 c1 x3 c5 c3 x2 x4 c2" [regex]::matches($string,'c\d') [regex]::matches($string,'c\d') | format-table -auto [regex]::matches($string,'c\d') | format-table Value, Index -auto [regex]::matches($string,'c\d') | format-table value ....also: [regex]$pattern = 'c\d' $pattern.matches($string) $pattern.matches($string) | format-table -auto $pattern.matches($string) | format-table Value, Index -auto $pattern.matches($string) | format-table value http://msdn2.microsoft.com/en-us/library/system.text.regularexpressions.regex.matches.aspx -- Kiron

Re: regex global match like Perl m//g John Cook 11.07.2007 11:32:04 Thanks. That's just what I needed to know. I'll summarize comparing Perl and PowerShell snippets. In Perl you would fill the array [ at ]cnums with all matches by $string = "x1 c4 c1 x3 c5 c3 x2 x4 c2"; [ at ]cnums = $string =~ m/c\d/g; The PowerShell analog would be $string = "x1 c4 c1 x3 c5 c3 x2 x4 c2" $cnums = ([regex]::matches($string,'c\d') | %{$_.value}) "Kiron" wrote: [Quoted Text] > I'm not sure about Perl's 'm//g' output, no Perl experience :( > To get all Regex matches in a string you can use .Net's Regex.Matches > method: > > $string = "x1 c4 c1 x3 c5 c3 x2 x4 c2" > [regex]::matches($string,'c\d') > [regex]::matches($string,'c\d') | format-table -auto > [regex]::matches($string,'c\d') | format-table Value, Index -auto > [regex]::matches($string,'c\d') | format-table value > > ...also: > > [regex]$pattern = 'c\d' > $pattern.matches($string) > $pattern.matches($string) | format-table -auto > $pattern.matches($string) | format-table Value, Index -auto > $pattern.matches($string) | format-table value > > http://msdn2.microsoft.com/en-us/library/system.text.regularexpressions.regex.matches.aspx > > -- > Kiron >

Re: regex global match like Perl m//g John Cook 11.07.2007 21:08:01 Thanks. I like the -matchall idea. The feedback link seems to be broken.

FYI When one needs to parse almost any thing in Windows perhaps Microsoft's Log Parser 2.2 PS> $string | LogParser.exe "SELECT text FROM STDIN WHERE text LIKE 'c%'" -i:tex tword -stats:off Text ---- c4 c1 c5 c3 c2 PS> There is also a way to add in other ways. At one time there was even a regex C# add-in for LogParser too! Just another way!
