Hi ,

I'm loading text into flash via an xml file but am having a slight problem - the length of the imported string is only 9 characters long ?? heres the actionscript and the xml file

myXML = new XML();
myXML.ignoreWhite = true;
myXML.load("/xml/banner.xml");
myXML.ref = this;
myXML.onLoad = function(succes){
    if(succes){
        var root = this.firstChild
        nodes = root.childNodes
        for(var i=0; i<nodes.length; i++) {        
            subnodes = nodes[i].childNodes
            text = subnodes[0].firstChild.toString()  
        }
    } else trace("Error loading XML document")
}
i = 1;
max = length(text);
trace(max);


<?xml version="1.0" encode="UTF-8"?>
<data>
<title name="HomepageBanner1">
<comments>blahblahblahblahblahblahblahblahblah</comments>
</title>
</data>

hi flaasher,

I'm pretty sure its the code thats at fault. If i just set

index="some text string";
max = length(text);
trace(max);

then i get the actual length of the string not just "9" returned.......... its wierd

i agree, its a typo on my part

would it be possible for you to try my code from my first post and you will see the problem of which i speak. basically the text that is loaded from the xml is measured at a length of  9 despite its actual length. it has nothin to do with how i've displayed that text on screen

Your problem is:

when the statement

i = 1;
max = length(text);
trace(max);

is executed, the variable text is not defined since the XMl has not been 100% loaded, the length of 'undefined' is 9.You can check this by adding a trace statement in the onLoad event handler and one trace statement at the end of the block of code. You'll see the that the one stay at the end of the code will come first. The suggested work around for this is you put your max,length blah blah in a function and call this when the xml is loaded. This is my code, based on yours


myXML = new XML();
myXML.ignoreWhite = true;

myXML.load("/xml/banner.xml");
myXML.ref = this;

myXML.onLoad = function(succes){
    if(succes){
            
            trace("This should come first")
            
        var root = this.firstChild
        nodes = root.childNodes
        for(var i=0; i<nodes.length; i++) {        
            subnodes = nodes[i].childNodes
            text = subnodes[0].firstChild.toString()  
        }
            
            runMe();
            
    } else trace("Error loading XML document")
}

//run this function after the XML has finish loading
function runMe()
{
      max = length(text);
      trace(max);
}


trace("This should come last");
