how to get the nodes length and sub nodes .

[Dhiyane]

Hi ,

find the scenario below .

<List1>

<List>

      <List1>

      <List1>

      <List1>

  </List>

<List>

      <List2>

      <List2>

      <List2>

  </List>

--

--

-

-

-

--</list1>

Here the list tag will be grow based on the I/p . Now what i want is how to get the length of <list >tag .

To implement above i used below code

var count = xfa.record.List1.List[0].nodes.length ; (Not working )

But if  var count = xfa.record.List1.nodes.length ; (working )

and also i want to remove some tag inside the <List > tag . How ?

Very Urgent .

Advance thanks .

In the first example you give the [] cause an issue for javascript as those are reserved for arrays. You can use the xfa.resolveNode("string") to get to your instance....something like this:

var count = xfa.resolveNode("xfa.record.List1.List[0]").nodes.length ;

Now using this syntax you can replace the occurance number with a variable and put it in a for loop:

for (i=0;i<= 10;i++){

     count = xfa.resolveNode("xfa.record.List1.List[" + i + "]").nodes.length

}

Hope that helps

while doing like belo w,

var count = xfa.resolveNode("xfa.record.List1.List[0]").nodes.length ;

the line not excuting

and if i use

var count = xfa.resolveNode("xfa.record.List1.List[0]").

then its returning value .

I hope anyone worked ealier linke this

Just looked at a couple of Data dom manipulation forms I have done before and I use

the following code:

var currentElement;
var obj;

//Get the nodes below the root node in the dataDom
obj = xfa.datasets.data.root.nodes;

//Set an initial value for the textField
TextField1.rawValue = "The values of the coap_flag are: ";

//Loop through the nodes in the obj set
for (i=0; i< obj.length ; i++){
//set the currentElement to the 1st child node
currentElement = obj.item(i);
//Check to see if it is an applicant node
if (currentElement.name == "applicant"){
  //It is an applican, now find the coap_flag node value and write it to the text field
  TextField1.rawValue += "\n" + xfa.resolveNode("xfa.datasets.data.root.applicant[" + i + "]").coap_flag.value;
}
}

In all my examples I always create an object then check the length of the object. I do not know why but it does work.

Hi .

I am not getting your answers .

[Dhiyane]

ffor E.g

<Root >

   <Child>

      <Nod1>

      <Nod1>    

   </child>

   <Child>

      <Nod1>

      <Nod1>    

   </child>

</Root>

Now we can use tthe above code like

xfa.datsets.data.Root.nodes

then it will return the length - 2

But now again i  want to trace last node. Here <nod1> and <nod1>.

How to get the nod1 tag or how to find the length of the <child> tag .

Advance thanks .

Try like below..

You should be able to go down one level by using nodes.item.

xfa.datsets.data.Root.nodes.item(0).value

xfa.datsets.data.Root.nodes.item(1).value

Thanks

srini ,

can you please clear this one .

Based on tthe our scenarion ,

xfa.datsets.data.Root.nodes.item(0).value

what is the result of this code .

I need to get the child node of <child> tag .

[Dhiyane]

Hi,

xfa.datsets.data.Root.nodes.item(0).value

here instead of value should be name to get the tag name .

Thanks .

[Srini_Dhulipall · Accepted solution]

Yes you need to use the name instead of value to get the tag name..

     xfa.datsets.data.Root.nodes.item(0).name

Thanks
