I have to extract m1,m2,m3 values using action script
Can anyone help me in writing this code .
Is the below code is enough for this
for (var i=0; i<xml.Terminal.length(); i++) {
if (xml.Terminal.Name.text()=="m1") {
voltage=xml.Terminal.Value.Array1.DBL.Val.text()
}
else if (xml.Terminal[i].Name.text()=="m2") {
current=xml.Terminal.Value.Array2.DBL.Val.text();
}
else if (xml.Terminal[i].Name.text()=="m3") {
temperature=xml.Terminal.Value.Array3.DBL.Val.text();
}
}
Menu_Content1.volt_val.text = voltage;
Menu_Content1.curr_val.text = current;
Menu_Content1.temp_val.text = temperature;
)
volt_val.text etc is for text display added in flash.

To parse a common formated tags in XML you have to first place them into a parent tage in your case create XML like this
<Response>
<**PARENT_TAG**>
<Terminal>
<Name>m1</Name>
<Value><Array1><DBL><Val>-0.143077</Val></DBL></Array1></Value>
</Terminal>
<Terminal>
<Name>m3</Name>
<Value><Array3><DBL><Val>-0.876611</Val></DBL></Array3></Value>
</Terminal>
<Terminal>
<Name>m2</Name>
<Value><Array2><DBL><Val>-0.459437</Val></DBL></Array2></Value>
</Terminal>
</**PARENT_TAG**>
</Response>
After that parsing of an XML in actionscript is very easy you just have to create an object of a XML and than use DOM format to get value of a particular tag As an example
var result:XML = new XML(event.target.data);
for(var i:int=0; i<result.PARENT_TAG.length; i++)
{
trace(result.PARENT_TAG.Terminal[i].Name);
}

yes,your idea is lead to right move.but you should first load xml file in object.
You can use XML like here or here in your project.
