Null results when trying to access children of the first item. I'm using Google App Scripts.
function parseXml() {
var url = 'https://example.xml';
var xml = UrlFetchApp.fetch(url).getContentText();
var document = XmlService.parse(xml);
var root = document.getRootElement();
var channel = root.getChild('channel');
var items = channel.getChildren('item');
Logger.log(items[1].getValue());
Logger.log(items[1].getChildren())
Logger.log(items[1].getChild('g:id'))
}
Output:

Finally, XML example. Sorry, I can't share the source URL.
<rss xmlns:g="http://base.google.com/ns/1.0" version="2.0">

I believe your current issue and your goal are as follows.
Logger.log(items[1].getChild('g:id')) returns null.<g:id>###</g:id> in item by modifying your script.When I saw your showing XML and your script, in your script, I thought that the namespace is required to be used. When this is reflected in your script, it becomes as follows.
Logger.log(items[1].getChild('g:id'))
Logger.log(items[1].getChild('id', XmlService.getNamespace("http://base.google.com/ns/1.0")))
or
Logger.log(items[1].getChild('id', XmlService.getNamespace("g", "http://base.google.com/ns/1.0")))
or
Logger.log(items[1].getChild('id', XmlService.getNamespace("http://base.google.com/ns/1.0")).getValue())
or
Logger.log(items[1].getChild('id', XmlService.getNamespace("g", "http://base.google.com/ns/1.0")).getValue())
Logger.log(items[1].getChild('id', XmlService.getNamespace("http://base.google.com/ns/1.0")).getValue()) might work.
