Parameter Description

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].deleteData(0,33);
 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.
