Hello again, my CURLOPT_WRITEFUNCTION function is working just fine to
write on buffer with any HTML page, but when I try to do it with any XML
page, it simply cut off the very beginning of the page.

CURLOPT_WRITEFUNCTION is writer(char *data, size_t size, size_t nmemb,
std::string *buffer)

I've took to stdout every char*data that curl inserted in the function,
but i didn't showed the beginning of the xml source. Like this:

int curlWrapper::writer(char *data, size_t size, size_t nmemb, string
return size * nmemb;

Even when I try setting CURLOPT_FOLLOWLOCATION to 1, the buffer variable
simply skip the beginning of the xml page like that:

Does anyone know the reason for that behaviour?
