Not able to correctly get the value of a KEYVAL node type. Entire file from the value location is taken as 'value'.

I am using rapidyaml v0.9.0.
I am trying to parse a yaml with the following code in C++20. However, the output shows the values of each key incorrectly considered.
I tried to verify my indentation online. Looks like the indentation of the yaml is correct. Even though in the following code snippet I am not able to show the indentation, as the markdown code block does not seem to work.

#include <iostream>
#include <ryml.hpp>
#include <ryml_std.hpp>

int main() {
  std::string yaml_content = R"( 
  LogicalMemoryList:
    - Name: "AXI_ACB"
      Type: "1W2W3W"
      Param: "4"
  )";

  ryml::Tree tree = ryml::parse_in_arena(ryml::to_csubstr(yaml_content));
  ryml::NodeRef root = tree.rootref();
  ryml::NodeRef list = root["LogicalMemoryList"];
  if (list.is_seq()) {
      for (ryml::NodeRef item : list.children()) {
          std::string name = item["Name"].val().str;
          std::string type = item["Type"].val().str;
          std::string param= item["Param"].val().str;
          std::cout << "Name: " << name << "\nType: " << type << "\nParam = " << param << std::endl;
      }   
  }
}

I am seeing following results:
Name: AXI_ACB"
Type: "1W2W3W"
Param: "4"

Type: 1W2W3W"
Instances: "4"

Param = 4"

However, I am expecting following results:
Name: AXI_ACB
Type: 1W2W3W
Param: 4

RTFM.

ryml::csubstr is a view, so it is NOT terminated by \0. You need to consider its length. So by using only .str you are constructing the multiple std::strings incorrectly, and that's why they go to the end of the file, because there is where the only \0 is located.

Do this instead:

ryml::csubstr n = item["Name"].val();
std::string name(n.str, n.len);

And likewise for the other strings.

Thank you. This worked. But does that mean extraction of every string value needs both the lines? Is there a less verbose way of extracting this value?

[biojppm]

Yes, using operator>>():

std::string name;
item["Name"] >> name;

Did you even look at the readme? It's right there in the first examples.
