E.g:
xpath_processor::xpath_processor (
const TiXmlNode * XNp_source_tree, ///< Source XML tree
const char * cp_xpath_expr) ///< XPath expression
: xpath_stream (cp_xpath_expr)
While calling xpath_stream if cp_xpath_expr is NULL, then it will call byte_stream constructor which will crash in below line:
u_length = strlen (cp_in) + 1; // strlen(NULL) crashes the code.
So, Null handling done in byte_Stream.
