Parse XML through JavaScript and get node value

Question

My code is like this

   var tariffdate = PriceSheet.children('TariffEffDate')[1].text;

Where I expect to get data inside TariffEffDate tag. But it gives me undefined instead.

I can Get <TariffEffDate>1999-01-01T00:00:00</TariffEffDate> as a result for code

  console.log(PriceSheet.children('TariffEffDate')[1])

But when I add .text to get data inside this node it is giving me undefined. Can anyone point out what I am doing wrong here?

Someone else had to use [1].firstChild.nodeValue instead of [1].nodeValue. Perhaps that would fix it? — h2ooooooo

You need to use Node.nodeValue instead of .text.

.children('TariffEffDate')[1] will give you a HTMLElement that inherits Node, but it won't give you a leaf node, meaning that this HTMLElement might have multiple children. This is why you cannot get the value of (technically) multiple child-nodes. You can access the first node by calling Node.firstChild.

Essentially, you want your final code to be:

var tariffdate = PriceSheet.children('TariffEffDate')[1].firstChild.nodeValue;
