HI, I am trying to learn xml in flash myself and am finding it v.hard!

All i am trying to do is create a little 'story' with 3 pages.I have content
loading into flash but I am unable to get the next 'sibling' into an array e.g.
the title. I can only get page1's title in the array but I can never get to
page 2.

Here is my xml:

<maincontent>
    <page1>
        <title>Who is he</title>
        <story>Duh a monkey that lives in the jungle, thats why they call him the
JUNGLE MONKEY</story>
    </page1>

        <page2>
        <title>What does he do?</title>
        <story>Swings around from tree to tree singing do wa di di .. di di dum di
di do...</story>
    </page2>

        <page3>
        <title>What is he like?</title>
        <story>Well you know - just a monkey doing his monkey business!</story>
    </page3>

</maincontent>

and here is my actionscript:

//load in the xml file
tut = new XML();
tut.ignoreWhite = true;
tut.onLoad = function(success) {
    if (success) {
        processstory(tut);
    }
};
tut.load("tut.xml");
function processstory(xmlDoc_xml) {

    titlearray = new Array();
    // xmlDoc_xml is now a reference to the XML
    // object where our information is stored


    for (var n = 0; n<xmlDoc_xml.firstChild.childNodes.length; n++) {



            trace(n);


        if (xmlDoc_xml.firstChild.firstChild.childNodes[n].nodeName == "title") {
            trace('The title is'+'
'+xmlDoc_xml.firstChild.firstChild.childNodes[n].firstChild.nodeValue);

            titlearray.push(xmlDoc_xml.firstChild.firstChild.childNodes[n].firstChild.nod
eValue);
    }

    trace(titlearray);
    }


}

This only traces the first title, how can i get to the second and the third so
i can then display them in my text box????

Any help/guidance or pointing to the right place is thankfully received!

Thanks

Bex

If you're using MX2004 or Flash 8 this tutorial will solve the whole problem without so much as one lick of AS.

Hope that helps

Howdy

XML is great if you understand all the concepts of node navigation, but this
takes too long and is not very interesting

Macromedia introduced the XpathAPI to allow us mere mortals a faster learning
curve.

So here is what I have done with your code, using the XpathAPI

The 3 key lines to look at are

Line 1 import: mx.xpath.XPathAPI, this imports the Xpath Class and allows
it to be used.

Line 10 var thePath_str:String = "maincontent/page/title"; this tells
Xpath Class what to look for

Line 11 var title_array:Array = XPathAPI.selectNodeList(this.firstChild,
thePath_str); this creates an Array of titles obtained

from the firstChild node of this, which in our case is maincnontent/page/title
or thePath_str which is the same.

I also altered your XML slightly, so that it conforms uniformaly.

Hope it all helps

import mx.xpath.XPathAPI;

var storyxml:XML = new XML();
storyxml.ignoreWhite = true;
storyxml.onLoad = function(success:Boolean) {
    trace("onload...");
    if (success) {
        trace("success...");
        // Retrieve all title nodes within maincontent/page/title.
        var thePath_str:String = "maincontent/page/title";
        var title_array:Array = XPathAPI.selectNodeList(this.firstChild,
thePath_str);
        for (var i:Number = 0; i < title_array.length; i++) {
            trace(title_array[i].firstChild.nodeValue);}
            } else {
                trace("error loading XML");
                }
                };

                storyxml.load("story.xml");

<maincontent>
<page id="1">
<title>Who is he</title>
<story>Duh a monkey that lives in the jungle, thats why they call him the
JUNGLE MONKEY</story>
</page>

<page id="2">
<title>What does he do?</title>
<story>Swings around from tree to tree singing do wa di di .. di di dum di di
do...</story>
</page>

<page id="3">
<title>What is he like?</title>
<story>Well you know - just a monkey doing his monkey business!</story>
</page>

</maincontent>
