replace string file

[Eric Kaplan]

I have a function that will take char buffer and dump all data into a
file.

How can I replace all
<givenname xsi:nil='true'/>

with

<givenname>.</givenname>


=============== ==============
int my_block_reader (void *userdata, const char *buf, size_t len)
{

char *szBuffer = new char[len + 1];
memcpy(szBuffer , buf, len);
szBuffer[len] = 0;
dumpfile << szBuffer;
delete[] szBuffer;

return 0;
}

The PCRE library from http://www.pcre.org/ makes it really easy to
replace a string based on regular expressions. Use PCRE as a
library/DLL, and the C++ wrappers turn the (somewhat obscure) API into
a rather trivial operation.

I think it's a mistake

Yes, can be return void.

this can be changed too

It's called by a function like - ne_add_response _body_reader(re q,
ne_accept_alway s, my_block_reader , NULL);

I am new to C++ I don't know it's C only

Hungarian notation? never heard of this though

May be more people can see this question?
