How to check if the node is null or empty?

[Former Member]

I need to know how one can check whether if a node is empty. I have five attributes in the node. But instead of checking each element, i just want to check if all the attributes are empty are not.

Any help will be appreciated.

Thanks

- You can check if a node has elements by checking size(). If size = 0, node is empty i.e it has no elements

I have five attributes in the node. But

If the current element exists, and you need to check whether the attribute in that element is null or not, then you need to know the attribute name. If there are too many attributes, you can consider putting all of them in an array and then iterating through the array with getAttributeValue(Arrayelement), to get each value and then checking that for null.

Hi Nahman ,

If you want to check only whether node is null then you can do that as mentioned above.

If you want to check whether the attributes are null or not then

for(int i=0;i<wdContext.nodeXXX().size;i++)

{

IPrivate<ViewName>.IXXXElement ele=(IPrivate<ViewName>.IXXXElement)wdContext.nodeXXX().getElementAt(i);

if(null !=ele.getAttributeValue("<<AttributeName>>") )

{

//

}

else

if(ele.getAttributeValue("<<AttributeName>>") .trim().equals(""))

{

//

}

}

hi

try this

if(wdContext.nodeMyNode()!=null && wdContext.nodeMyNode().size()!=0)
{
}
