Complete Comment Object Reference

Definition and Usage

The replaceData() method replaces data in a comment node.

Syntax

commentNode.replaceData(start,length,string)

Example

The following code fragment loads "books_comment.xml" into xmlDoc using loadXMLDoc() and replace "Simple" with "Easy" in the comment node 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
  x[i].replaceData(4,6,"Easy");
  document.write(x[i].data);
  document.write("<br />");
  } 
}
