I'm trying to extract an element called lastupdated from a parent node called episode: data -> Episode -> lastupdate

if I wrote:

episodeList = xmlDoc.getElementsByTagName("Episode");
console.log(episodeList[1].getElementsByTagName("lastupdated")[0])

it returns me the item zero of a list of length 1 but with the lastupdated tags

If I wrote:

console.log(episodeList[1].getElementsByTagName("lastupdated")[0].nodeValue)

it returns null! why is that?

responding: textValue returns null

xml part: TextContent also return null. here goes the xml:

How I Met Your Mother is a edy about Ted and how he fell in love. It all started when Ted's best friend, Marshall, dropped the bombshell that he was going to propose to his longtime girlfriend, Lily, a kindergarten teacher. At that moment, Ted realized that he had better get a move on if he, too, hopes to find true love. Helping him in his quest is his friend Barney, a confirmed bachelor with endless, sometimes outrageous opinions, a penchant for suits and a foolproof way to meet women. When Ted meets Robin, he's sure it's love at first sight, but destiny has something else in store.

• javascript
• xml
• dom

1 Answer 1

You need to use nodeValue instead of nodevalue. Javascript is case sensitive and there is no nodevalue property of DOM Node.

UPDATE: Also you need to use textContent if you want text value within xml node. For more information look textContent and nodeValue references.
