(AS2) XML - convert < to read as HTML

2009-03-25

Hi,
I'm bringing in some XML from a PHP generated page. unfortunately they PHP generates the XML as follows:

Code:

<moreInfo>&lt;b&gt;Abstract Painting&lt;/b&gt;&lt;br /&gt;1963&lt;br /&gt;170.00 x 215.00
 cm&lt;br /&gt;Oil on canvas&lt;</moreInfo>

Rather than processing and reading the data as HTML, flash will print this out as html:

Code:

<b>Abstract Painting</b><br />1963<br />170.00 x 215.00 cm<br />Oil on canvas<br />

I'm using AS2, a HTML enabled text field and i've tried the unescape/escape function. It looks like unescape will only work on hexadecimal data.

Any ideas on how to get flash to read this as html?

Cheers,
Luke.

Edited (I found a possible solution)

Here's a test I ran

Code:

var m:String= "<items><one>plain</one><two><![CDATA[this is <i>italic</i>]]></two></items>";
var my_xml:XML = new XML(m);
trace("using firstChild:");
for (var i = 0; i<my_xml.firstChild.childNodes.length; i++) {
    trace("\t"+my_xml.firstChild.childNodes[i].firstChild);
}
trace("");
trace("using firstChild.nodeValue:");
for (var i = 0; i<my_xml.firstChild.childNodes.length; i++) {
    trace("\t"+my_xml.firstChild.childNodes[i].firstChild.nodeValue);
}

Output is

Code:

using firstChild:
	plain
	this is &lt;i&gt;italic&lt;/i&gt;

using firstChild.nodeValue:
	plain
	this is <i>italic</i>

As you found out, the problem is not how PHP interprets the page, its how Flash does. Take a look at your raw php generated XML in a browser and you will not see those characters. nodeValue is the solution you are looking for.

Thanks for your help, this is looking good. It's returning "null" at the moment. Can you figure out what's happening? Here's what I've got:

AS2

ActionScript Code:

moreInfoTxt.htmlText = mainNode.childNodes[moreInformation].childNodes[0].nodeValue

XML:

Code:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<songs>
	<song trackTitle="track tite1">  
		<moreInfo><![CDATA[ &lt;b&gt;Abstract Painting&lt;/b&gt;&lt;
br /&gt;1963&lt;br /&gt;170.00 x 215.00 cm&lt;br /&gt;Oil on canvas&lt;

	</song>
</songs>

(I've broken the xml apart so the forum page holds together)

Hi,
All fixed! Thanks for your help. I out that i was declaring a var that messed with it. Basically, nodeValue worked a treat.

Thanks UShock team.

full solution:
mainNode.childNodes[moreInformation].childNodes[0].nodeValue.split("<").join("<").split(">").join(">");
