Accessing XML DOM child nodes by name

Question

I want to access the textContent property of an XML object in JavaScript. The root item has several children which also have some children themselves. To get the children on

Answer 1

The problem is the spaces between the nodes are automatically made textNodes. Check if the node at xmlDoc.documentElement.childNodes[i] is a textNode (nodeType 3) before you try to find children. I also removed your globals i and key in this example.

var node, childNodes = xmlDoc.documentElement.childNodes;
for(var i = 0; i < childNodes.length; i++)
{
  node = childNodes[i];
  if(node.nodeType !== Node.TEXT_NODE) console.log(node.getElementsByTagName('child1')[0].textContent);
}

Answer 2

Using the following obtains the desired value of the child1 nodes for me..

var k = xmlDoc.getElementsByTagName("child1");

for(var i = 0; i < k.length; i++)
{
  console.log(k[i].childNodes[0].nodeValue);
}

Answer 3

Try getElementsByTagName('child1')[0].nodeValue
