Node.js + Selenium How to parse html properly

Question

I would like to traverse through all th elements on my page:

enter image description here

The path to the th elements is div[id='specs-list']/table/tbody/tr/th:

My script is:

var webdriver = require('selenium-webdriver');

var driver = new webdriver.Builder().
    withCapabilities(webdriver.Capabilities.chrome()).
    build();

driver.get('http://www.gsmarena.com');
driver.findElement(webdriver.By.name('sName')).sendKeys('iphone 4s');
driver.findElement(webdriver.By.id('quick-search-button')).click();


driver.findElement(webdriver.By.xpath("//div[@id='specs-list']/table/tbody/tr/th")).then(function(elem){
    console.log(elem.getText());
});

But I get:

drobazko@drobazko:~/www$ node first_test.js
{ then: [Function: then],
  cancel: [Function: cancel],
  isPending: [Function: isPending] }

Instead text General Questions are:
1. How can I get correct text string?
2. How Can I traverse through many th elements?

1 - How can I get correct text string?

driver.findElement(webdriver.By.xpath("//div[@id='specs-list']/table/tbody/tr/th")).getText().then(function(textValue){
    console.log(textValue);
});

Or

driver.findElement(webdriver.By.xpath("//div[@id='specs-list']/table/tbody/tr/th")).then(function(elem){
    elem.getText().then(function(textValue) {
        console.log(textValue);
    });
});

Why?

Both findElement and getText() return you a promise. You would get similar result if you try to console.log(driver.findElement(....))

2 - How Can I traverse through many th elements?

driver.findElements(webdriver.By.xpath("//div[@id='specs-list']/table/tbody/tr/th")).then(function(elems){
    elems.forEach(function (elem) {
        elem.getText().then(function(textValue){
            console.log(textValue);
        });
    });
});
