Answer 1

If you put an id on the label like this

<input type="radio" name="vote_x" value="5">
<label id="for_vote_x" for="vote_x">blabla</label>

You can then use

var textinlabel = document.getElementById("for_vote_x").innerHTML;

Edited: With out using an id for the label element

var labelElements = document.getElementsByTagName("label");
for (var i = 0, var labelElement; labelElements[i]; i++) {
  if (labelElement.getAttribute("for") == "vote_x") {
    //this is the labelElement you want
    //code goes here
  }
}

Ideally you would want to create a Generic function for this

function getlabelforinput(inputname) {
    var labelElements = document.getElementsByTagName("label");
    for (var i = 0, var labelElement; labelElements[i]; i++) {
      if (labelElement.getAttribute("for") == inputname) {
        return labelElement
      }
    }
    return null;
}
