javascript selectNodes on parsed xml

Question

How can I use the selectNode() function on a parsed XML message in javascript?

<script>
var xmlStr = "<tagName>some text here</tagName>";
var xmlDoc = (new DOMParser()).parseFromString(xmlStr, "text/xml");
var nodes = xmlDoc.selectNodes('tagName');
</script>

I get error for this code: Uncaught TypeError: xmlDoc.selectNodes is not a function

There’s no such thing as a `selectNodes` function on an `XMLDocument`. Use `querySelector` or `querySelectorAll` instead. — Sebastian Simon, Apr 25 '16 at 18:27

Actually XmlDocument.SelectNodes method exists, but in the .NET Framework.

In JavaScript, you can use the getElementsByTagName() method

var nodes = xmlDoc.getElementsByTagName("tagName")[0];

@user6186801 you probably mean the code without the [0]. I.e., the nodes variable is an array, not it's first element. right? – primehunter Feb 10 '21 at 14:03

selectNode() is not on javascript, you meant that you are looking for equivalent function?

nodes.getElementsByTagName("tagname");

Thanks, totally acceptable answer. But I think APPinAIR answered a little faster. – nagy.zsolt.hun Apr 25 '16 at 19:24
