Hi Team,
Two questions below:
1/ � Iam getting one more crash where iam passing std::string to a get_children() function. Iam using std::string type as inp argument. is this ok to pass std::string to an ustring. I learnt that if it is english then it will not be an issue.�
std::string node_str = "example"
Node::NodeList tmp_lst = rnode->get_children( node_str );
What if i change the inp argument to function call as node_str.c_str(). Please let me know.
2/ � Iam getting the below crash trace with the function code ( see the code after stack trace here ). This happens some times.
