Save an XML node tree to a string. This function returns the total number of bytes that would be required for the string but only copies (bufsize - 1) characters into the specified buffer. The callback argument specifies a function that returns a whitespace string or NULL before and after each element. If MXML_NO_CALLBACK is specified, whitespace will only be added before MXML_TEXT nodes with leading whitespace and before attribute names inside opening element tags.
