boost::regex_replace issue

[Yahooooooooo]

Just practicing BOOST regular expressions....giving errors...
-- wanted to replace SPACE with NULL.


#include <iostream>

using namespace std;
boost::regex rex1;
extern const char* pre_expression= " ";
extern const char* pre_format="";

int main(void)
{
string line;
//boost::regex rex1(" ",boost::regex:erl|boost::regex::icase);
rex1.assign(pre_expression);
boost::regex rex2;

ifstream fh("/tmp/log.conf");
getline(fh,line);
cout << line << endl;

std:stringstream osstr(std::ios:ut);
std:stream_iterator<char,char> oi(osstr);


boost::regex_replace(oi,line.begin(),line.end(),rex1,pre_format,boost::
match_default | boost::format_all);

getline(fh,line);
cout << line << endl;
fh.close();
return 1;
}

Just practicing BOOST regular expressions....giving errors...

Your example compiles fine for me with MSVC 7, Windows.
You might want to try the Boost forums.
