2.

use this code:
    YAML::Parser parser(ifstream("test2.yml"));
    //YAML::Parser parser(ifstream("items9.yml"));
    YAML::Node doc;
    if(! parser.GetNextDocument(doc)) exit(0xbadf00d);

    vector<string> string_vector;// = getkeys(doc);
    for(auto it = doc.begin(); it != doc.end(); ++it)
    {
        string s;
        it.first() >> s;
        string_vector.push_back(s);
    }

    for(auto it = string_vector.begin(); it != string_vector.end(); ++it)
        cout << *it << "\n";

3. it doesn't get all nodes, I don't know why, it still is valid yaml

using 0.3.0, windows xp, visual C++ 10

I don't think it's caused by hash key collision, because the data I use in my 
app are common english words, and I have the same issue.

Could you please post the output you get from the code you posted?

Can you upload the file "test2.yml" so I can see exactly the bytes you're using?

The line

YAML::Parser parser(ifstream("test2.yml"));

shouldn't actually compile. There is no constructor for YAML::Parser that takes 
a std::istream by value or reference-to-const; only by reference.

Instead, you should do something like

ifstream fin("test2.yml")
YAML::Parser parser(fin);

My best guess as to what's happening is that in the confusion that follows 
binding a temporary to a non-const reference, it only keeps the file stream 
open long enough to read one chunk of the file into memory, so you're only 
getting the first portion of the file.

Oh, ok, well I'll fix it.

So why does it compile ? Isn't visual C++ not supposed to compiled it ?

That's right, Visual C++ should issue an error here. See
