XML DOM data Attribute

Definition and Usage

The data attribute returns the text content of the comment.

Syntax:

commentNode.data

Example

The following code segment uses JavaScript functions loadXMLDoc() Load the XML file books_comment.xml Load xmlDoc and output the comment text content of the first <book> element:

xmlDoc=loadXMLDoc("books_comment.xml");
x=xmlDoc.getElementsByTagName("book")[0].childNodes;
for (i=0;i<x.length;i++)
{ 
if (x[i].nodeType==8)
  { 
  //Process only comment nodes
  document.write(x[i].data);
  document.write("<br />");
  } 
}

The output of the above code:

(Book 6) (Hardcover)

In this example, we use a loop and if statement to perform processing that is only for comment nodes. The node type of comment nodes is 8.
