The most preferred method is to use Xerces library..

template <typename CharType>
void read_file_to_string(
const CharType* filename,
basic_string<CharType>& buff)
{
ifstream fs(filename);
istream_iterator<CharType> fbegin(fs);
istream_iterator<CharType> fend;
copy(fbegin, fend, buff.begin());
}

the most preferred by who? I use expat http://expat.sf.net

TinyXML is a light weight option for reading XML files:

I am also using xerces to parse the xml. But now i need the xml contents
to be as std::string

I have trying to compile this code i found somewhere else:

std::ifstream ifs("file.xml");
std::string file_string( std::istreambuf_iterator<char>(ifs),
std::istreambuf_iterator<char>() );


but get this error:

: error C2664: '__thiscall std::basic_string<char,struct

>::std::basic_string<char,struct std:

:char_traits<char>,class std::allocator<char> >(const char *,unsigned

>' to 'const char *'

No user-defined-conversion operator available that can perform
this conversion, or the operator cannot be called


I am using VC6.0 compiler

Thx in advance.

by everyone else except you..

ok jokes apart... if you look at the details.. expat is fine.. written
completely in c, has great performance results, compatible with C/C++ etc
etc..
but xerces beats expat, considering that it can go well with C/C++ and java
and also the number of OS supported..by it is far more than expat


its not enough ? ok
encodings supported by xerces are UTF 8/16 , UCS 4 , ISO8859-1 , ASCII ,
EBCDIC , CP-1252
hmmm.. expat unfortunately supports only UTF 8

So that gets its popularity..
yes.. but mind you xerces is bulky when compared to expat.

I get your next question mehturt.. "benchmarked by who"
check this .. http://xmlbench.sourceforge.net/index.php?page=results.php


but mehturt.. i agree that expat is very popular parser.. so going back to
Dinh's question,
why not try out this expat.. ( I havent tried it yet )
