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].replaceData(4,6,"Easy");
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].replaceData(4,6,"Easy");
document.write(x[i].data);
document.write("
");
}
}

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.
