XML DOM appendData() Method
Comment Object
Definition and Usage
The appendData() method adds data at the end of a comment node.
Syntax
commentNode.appedData(string)
| Parameter | Description |
|---|---|
| string | Required. The string to add to the comment node |
Example
The following code fragment loads "books_comment.xml" into xmlDoc using loadXMLDoc() and appends text to the first comment element:
Example
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
x[i].appendData(" Special Offer");
document.write(x[i].data);
document.write("<br />");
}
}
x=xmlDoc.getElementsByTagName("book")[0].childNodes;
for (i=0;i<x.length;i++)
{
if (x[i].nodeType==8)
{
//Process only comment nodes
x[i].appendData(" Special Offer");
document.write(x[i].data);
document.write("<br />");
}
}
Output:
125 Simple and Delicious Recipes (Hardcover) Special Offer

In the example above we use a loop and an if-test to make sure we only process comment nodes. A comment node has a node type of 8.
