XML DOM replaceData() Method

Complete Comment Object Reference

Definition and Usage

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

Syntax

commentNode.replaceData(start,length,string)

Parameter	Description
start	Required. Specifies where to begin replacing characters. Start value starts at zero
length	Required. Specifies how many characters to replace
string	Required. Specifies the string to insert

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 />");
  } 
}

Output:

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.
