javascript--can't get textContent of [Object Text]?

I want the script to find where it says, "anyword" in the xml (within the tag of course), and stop on that. the below accomplishes that fine. 

 var xmlDoc = loadXMLDoc("nhl.xml");
    var x = xmlDoc.getElementsByTagName("tagname");
    for (var i=0;i<=x.length;i++){
        if (x[i].textContent = "anyword") {
            var variable = x[i].textContent;
        }
    }

However I want to take it one step further and be able to set 'variable' to the next node after it finds 'anyword'. so i tried something like this and it came back with the very last element in the collection, instead of the next one.

var xmlDoc = loadXMLDoc("nhl.xml");
    var x = xmlDoc.getElementsByTagName("tagname");
    for (var i=0;i<=x.length;i++){
        if (x[i].textContent = "anyword") {
            var variable = x[i+1].textContent;
        }
    }

so i edited the last line again and made it

var variable = x[i].nextSibling.textContent;

this came back null. ripping my hair out here. if it helps to answer any, if i just put it x[i].nextSibling it comes back [Object Text]

any help?

By x[i].textContent = "anyword" do you mean x[i].textContent == "anyword"?

This is a common problem for people. The modern browsers (basically all them except IE) will add text nodes between elements. Those text nodes only contain the whitespace and aren't of a lot of use. Use this function to find the next node.

function nextSibling(node) {
  do {
    node = node.nextSibling;
  } while (node && node.nodeType != 1) ;
  return node
}

It gets explained pretty well here: JavaScript XML Parsing

            var variable = x[i+1].textContent;
        }
    }

I did't look in details but this seems odd to me :

for (var i=0;i<=x.length;i++)

Have you tried 

for (var i=0;i<x.length;i++)
