XML output in flash problem

[stockdalep]

Hi

I have a simple xml file loaded into flash 8 as below.

<?xml version="1.0" encoding="UTF-8"?>
<phoneBook>
<contact id="1">
<name>Sas Jacobs</name>
<address>123 Some Street, Some City, Some Country</address>
<phone>123 456</phone>
</contact>
<contact id="2">
<name>John Smith</name>
<address>4 Another Street, Another City, Another Country</address>
<phone>456 789</phone>
</contact>
<contact id="3">
<name>Jo Bloggs</name>
<address>7 Different Street, Different City, UK</address>
<phone>789 123</phone>
</contact>
</phoneBook>

Using this code to loop through and display in a text box.

xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = myFunction;
function myFunction(success:Boolean):Void {
if (success) {
//process data
trace("loaded");
Rootnode = this.firstChild;
num = Rootnode.childNodes.length;
trace(num);
for (i=0; i<Rootnode.childNodes.length; i++) {

Name = Rootnode.childNodes[i].childNodes[0].firstChild.nodeValue;
Address = Rootnode.childNodes[i].childNodes[1].firstChild.nodeValue;
Phone = Rootnode.childNodes[i].childNodes[2].firstChild.nodeValue;
id = Rootnode.childNodes[i].attributes["id"];
ans += "<b><br><br>"+ Name +"<br>" + Address +"<br>" + Phone + id + "<br><br>";
my_text.text = ans;
}
} else {
trace("Not Loaded");
}
}
xmlData.load("address.xml");



The problem is the first word is UNDEFINED then it prints out perfectly. How can I get rid of the UNDEFINED or more importantly where is it coming from the output is this.

undefined

working in MX6 here, I get similiar results to yours with the html tab enabled in the textfield properties.
the workaround was deselecting the tab and setting it in script.

ans = "<b><br><br>"+ Name +"<br>" + Address +"<br>" + Phone + id + "<br><br>";
my_text.html = true;
my_text.htmlText += ans;

Why ?? Go figure !! Anyone enlighten me

hope it works for you

Thank for the help the only way I found out of this was to set the var ans to ans = "";
outside of the loop the is building the string. Odd ???

It's not odd. You are concatenating the lines in the loop but have to define the first value of the field to be empty before the loop begins. Flash 8 is unforgiving with things like this.

ans="";
for (i=0; i<Rootnode.childNodes.length; i++) {

Name = Rootnode.childNodes[i].childNodes[0].firstChild.nodeValue;
Address = Rootnode.childNodes[i].childNodes[1].firstChild.nodeValue;
Phone = Rootnode.childNodes[i].childNodes[2].firstChild.nodeValue;
id = Rootnode.childNodes[i].attributes["id"];
ans += "<b><br><br>"+ Name +"<br>" + Address +"<br>" + Phone + id + "<br><br>";
my_text.text = ans;
}

You should refine the line to send the completed string as htmlText since you have tags (like Dog used above)

my_text.htmlText = ans;
