Getting the element's tag name about fluentdom HOT 5 CLOSED

Not really, FluentDOM\Query is a node list, just like jQuery. If you're working with a single node, using the extended DOM node objects is not a bad idea. If you iterate a FluentDOM\Query the items are node objects. FluentDOM\Element even provides ArrayAccess for the attributes.

See: https://github.com/FluentDOM/FluentDOM/wiki/Element-ArrayAccess

A node name is complex. It is actually 3 properties. DOMNode::$nodeName, DOMNode::$localName and DOMNode::$namespaceURI. The node name is the tag name including the namespace prefix. It is not stable (the namespace prefix can change and is optional). To validate a node you should verify the local name and the namespace URI.

if ($node->namespaceURI= 'urn:foo' && $node->localName = 'foo') {
  ...
}

So I suggesting working with the element nodes and only putting them back into a FluentDOM\Query if you really need the traversing/manipulation API again.

Additionally FluentDOM\Query::is() and FluentDOM\Query::filter() could be used to verify the condition.

Thanks Thomas, but I still believe adding functions for getting full name or local name to your query/element object would be very useful. Something like this:

$fd->find('//div')->children()->first()->getlocalTagName()

• Most XML documents used in the web for casual porpuses don't have namespaces. Including, HTML.

Why not just:

$fd->find('//div')->children()[0]->localName

or as a validation

$fd->find('//div')->children()->first()->is('local-name() = "span"')

The jQuery API is large and a little messy. So I am feeling a little queasy about adding more methods. Especially if they are not in jQuery.

I understand your feeling ... but ... you know ... people care about methods that are not there, not the extra methods that they do not use. It's also quite a useful feature. And "children()[0]->localName" is not as elegant as "getLocalName()".
Anyway, it's your library and you're in charge. Do what you believe is the best...

Well it is FluentDOM($node)[0]->localName vs FluentDOM($node)->getLocalName(). The difference is not that big.
