    I only hardcoded that to give an example. 

     

    It could be something like:

     

    var name, ID, BaseNo;

for(var i=0; i<totalPropertyNodes;i++){
  name = GetNameFromXml(); 
  ID = GetIDFromXml();
  BaseNo = GetBaseNoFromXml();
}

new Property(name, ID, BaseNo)

    Then it is no longer hardcoded.

     

    I am not sure how you get the values from the xml, and I still don't quite understand the result you are expecting.

Hi will_fetherolf ,

 

Storing value like this obj[attributename1] = value; , will have the last read value stored only .

Not sure if I understand you correctly, but you want something like this?:

 

function Property(name, ID, BaseNo){
  return {
    "name" : name,
    "ID" : ID,
    "BaseNo" : BaseNo
  }
}

var TestValues = [
  new Property("name1", "0", "34"),
  new Property("name2", "1", "35"),
  new Property("name3", "2", "36")
]

Now you have a single Array variable that has all the properties.

To get the ID of property 2, you can do

 

TestValues[1].ID

    Hi k_de_boer03 ,

     

    Thank you for the reply . Property names would remain same in no but there values would not be static. For Ex : Name will not only have 2 values . it would increase. and there hard coding like 

    new Property("name1", "0", "34"),

    would not help .

        When you use the loop like this, you'll have to initialize your base "property" object, or you're going to overwrite it each time.

         

        for (i=0; i<totalPropertyNodes; i++)
{
  TestValues[i] = {};
  TestValues[i].name = GetNameFromXML();
  TestValues[i].ID = GetIDFromXML();
  TestValues[i].BaseNo = GetBaseNoFromXML();
}

         

        If you wanted to be really slick you could loop through the Property nodes in your xml, and as you iterate through the nodes you could get an attribute collection (using Node.attributes), and do something like this:

        for (i=0; i<totalPropertyNodes; i++)
{
  currentNode = propertyNodeList.nextNode();
  attributeList = currentNode.attributes();
  TestValue[i] = {};
  for(j=0; j<attributeList.length; j++)
  {
    TestValue[i][attributeList.item[j].nodeName] = attributeList.item[j].nodeValue;
  }
}
