Read Text length in ChildNode for autoScroll

[Twandeman]

Hi everyone,
I'm nearly finished making a website with all of it's content in one xml file.
I have a textbox which reads its content from the xml file with. I'm using a scrollcomponent on the textbox. Now I want to autohide the scrollcomponent if the number of characters is below some number.

How can I read-in the number of text characters in the ChildNode?

var Desc = project.childNodes[3].firstChild;
detail_mc.description.xmltext.text = Desc;
//Auto Scroll description
if (project.childNodes[3].firstChild.nodeValue >= 10) {
    detail_mc.scrolldesc._visible = true;
    } else {
    detail_mc.scrolldesc._visible = false;
} 

If I try this line:
var Desc = project.childNodes[3].firstChild.nodeValue;
The textbox stays empty, so that doesn't work somehow.

Can anyone give me a hand?
Thanks!

try

var Desc = String(project.childNodes[3].firstChild.firstChild);

Hi,

I think the string .length property is what you need..

AS:

// if "project.childNodes[3].firstChild" is  a text node then use
// (for text nodes, the "nodeValue" is a string)
var Desc = project.childNodes[3].firstChild.nodeValue

// if "project.childNodes[3].firstChild" is NOT a text node then use 
// var Desc = project.childNodes[3].firstChild.toString()

detail_mc.description.xmltext.text = Desc; 

//Auto Scroll description 
if (Desc.length >= 10) { 
    detail_mc.scrolldesc._visible = true; 
} else { 
    detail_mc.scrolldesc._visible = false; 
}

// Equivalent to the previous "if" condition is this:
// detail_mc.scrolldesc._visible=(Desc.length >= 10)?true:false 

As i wrote in the last line of the previous code, Equivalent to your "if" condition, is this (one) line (use the ternary ? -conditional operator) :

detail_mc.scrolldesc._visible=(Desc.length >= 10)?true:false

(is not something important, just if want a bit shorter code)

Thanks guys! You were both right!
First I had to make it a string like Cesspenar suggested, and then I could use the Desc.length property like Kostas Zotos suggested.
Thanks a lot!
