Hi,
First of all, please always state your platform and libxml2 version
when asking for help. Also provide a complete standalone code example
of your problem.

This will never work. libxml2 is C not C++ and the API only works with
NULL terminated sequences of UTF-8 bytes, not STL strings.

Your example works here (libxml2 on GNU/Linux):
#include <string.h>
#include <libxml/parser.h>
#include <iostream>
int main (int argc, char *argv[])
{
LIBXML_TEST_VERSION
std::string sXml("<foo/>");
int nLen = (int)sXml.size();
char* pszContent = new char[nLen + 2];
strncpy(pszContent, sXml.c_str(), nLen + 2);
pszContent[nLen] = '\n';
pszContent[nLen + 1] = '\0';
xmlDocPtr pXmlDoc = xmlReadMemory(pszContent, nLen, "xml", "UTF-8", 0);
if (pXmlDoc == NULL)
return(1);
delete[] pszContent;
pszContent = NULL;
xmlFreeDoc(pXmlDoc);
xmlCleanupParser();
return(0);
}

Though the reason you are adding an extra newline after the XML eludes
me at the moment. Note that I had to use strncpy instead of strcpy_s,
as I'm on GNU/Linux where strcpy_s doesn't exist.
