tr1::regex

[sashoalm]

I need a quick example on how to use tr1::regex class from VS2008. I have a string like "something" "something" ... and I want to get only what's between the first quotes. In VC6 find/replace it would look Find: "\([^"]\)" Replace: \1

Try Namespace: System::Text::RegularExpressions

#using <System.dll>

using namespace System;
using namespace System::Text::RegularExpressions;
int main()
{

Regex^ rx = gcnew Regex( "\\b(?<word>\\w+)\\s+(\\k<word>)\\b",static_cast<RegexOptions>(RegexOptions::Compiled | RegexOptions::IgnoreCase) );

String^ text = ""something" "something"";
MatchCollection^ matches = rx->Matches( text );
Console::WriteLine( "{0} matches found.", matches->Count );

for each (Match^ match in matches)
{
String^ word = match->Groups["word"]->Value;
int index = match->Index;
Console::WriteLine("{0} repeated at position {1}", word, index);
}
}

I don't thing he's referring to managed code. See TR1[^] here.

TR1's regex is based on Boost[^]'s Regex[^] library. See the sample presented here[^], for example. You may have to alter the namespace and #include, but that should be about all.
