How do I access XML node NAMES?

**bunner bob** · 01-10-2009, 03:50 AM

I'll try to explain what I want to do in plain english, because I'm having trouble working it out in AS...

The following XML represents the structure of a website. First I go through all the "second level" nodes to determine which of them has a "subNavName" node in it - this tells me whether that section of the site has subnav. That part I have worked out:

Code:

for each (var nodeI:XML in contentXML.*)
{
	if (nodeI.subNavName) // this site section has a node called 'subNavName'
	{
		
	}
}

Then I need to get all the OTHER nodes at the SAME LEVEL within that "second level" node. In the "works" state these are "vancouverRiverfront" and "progressRidge". I need to get the NAMES of these elements (i.e. I need to get "vancouverRiverfront" and "progressRidge") - I can't figure out how to a) look at all the elements that are one level "down" within the "works" state and b) get the node names, to determine 1) which one is "subNavName" and so doesn't need any further retrieving, and 2) which ones are NOT "subNavName", and get their name, and continue tunneling down to retrieve other content (which I CAN do).

Everything I read tells me how to access node CONTENT, but not node names within a given node. Is there a practical way to do this, or should I not be naming my nodes with a string I want to be able to retrieve?

The XML:

Code:

<?xml version="1.0" encoding="utf-8"?>
<content>
	<home>
		<elements>
			<element>
				<text>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Ut in magna quis enim placerat elementum. In magna. Nam dignissim turpis in dolor. Donec sit amet leo et nulla consequat iaculis.</text>

	</home>

PHP Code:


for each (var nodeI:XML in contentXML.*) {

    for each (var nodeJ:XML in nodeI.*) {

        if (nodeJ.name() == "subNavName") trace ("aaa "+nodeJ.name())

        else trace ("bbb "+nodeJ.name())

    }

}

Right on! I thought it had to be something easy, but I was trying to do it as either a property (nodeJ.name) or a "get" function (nodeJ.getName()).

One more question - my first conditional - "if (nodeI.subNavName)" - doesn't seem to be limiting me to just the nodeI's that contain a node called subNavName. When I do:

PHP Code:


if (nodeI.subNavName) // this site section has a node called 'subNavName'

{

    for each (var nodeJ:XML in nodeI.*)

    {

        if (nodeJ.name() != 'subNavName')

        {

            trace(nodeJ.name());

        }

    }

}

on the XML above I get:

PHP Code:


elements

vancouverRiverfront

progressRidge

studies

thinking

planning

- but I shouldn't be getting the first one - "elements" - because the "home" node doesn't contain a node called 'subNavName'.

Or rather - that's how I want it to work. But I seem to be doing something wrong. How should I be asking "if this node has a node called 'subNavName', then look at each node in this node - otherwise don't"?

Thanks!

easy way is to skip the first node:

PHP Code:


for (var i:uint = 1; i < contentXML.children().length(); i++) {

    var nodeI:XML = contentXML.children()[i];

    for each (var nodeJ:XML in nodeI.*) {

        if (nodeJ.name() != "subNavName") trace (nodeJ.name())

    }

}

Ah - but it needs to be more flexible. In this case I have another section (not shown) after the XML shown that doesn't have subnav. I really need to determine which top-level nodes _have_ subnav, and only proceed on those.

**bunner bob** · 01-10-2009, 02:26 PM

Got it:

PHP Code:


if (nodeI.subNavName.toString().length > 0)

**chulimanga** · 01-10-2009, 02:29 PM

If you'll keep subNavName in first position

PHP Code:


for each (var nodeI:XML in contentXML.*) {

    if (nodeI.children()[0].name() == "subNavName") {

        for each (var nodeJ:XML in nodeI.*) {

            if (nodeJ.name() != "subNavName") trace (nodeJ.name())

        }

    }

}
