Re: [xml] How to add datatypes

[samaram s <samaram007 gmail com>]

Thank you so much.

But when i tried as you said, it says 2nd argument should be xmlchar* type not char* . when i type casted it, it doesn't like it.

Any idea?

(note: it's not a good idea to give your variable the same name as a
library function)

Yes, but not by libxml :)

wchar_t buffer[50];
wsprintf(buffer, L"Created on Date %s and Time %s ", date, time);

Now you need to convert buffer to UTF-8, because that's what libxml2 uses.

setlocale(LC_CTYPE, "UTF-8");
char buffer_utf8[200]; // 4x the original, just in case
wcstombs(buffer_utf8, buffer, 200 /* max bytes written */);

com1 = xmlNewDocComment(doc, buffer_utf8);

In this case, you can just pass the variable holding Val to xmlNewProp
(again, it should be UTF-8).
