Definition and Usage
The insertData() method inserts data to a comment node.
Syntax
commentNode.insertData(start,string)
| Parameter | Description |
|---|---|
| start | Required. Specifies where to begin inserting characters. Start value starts at zero |
| string | Required. Specifies the string to insert |
Example
The following code fragment loads "books_comment.xml" into xmlDoc using loadXMLDoc() and inserts a string to the first comment node:
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].insertData(25,"Italian ");
document.write(x[i].data);
document.write("
");
}
}
x=xmlDoc.getElementsByTagName("book")[0].childNodes;
for (i=0;i<x.length;i++)
{
if (x[i].nodeType==8)
{
//Process only comment nodes
x[i].insertData(25,"Italian ");
document.write(x[i].data);
document.write("
");
}
}
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.
