Re: Inserting a text node before an element node useing the XML DOM

["Spencer Tickner" <spencertickner@gmail.com>]

Sorry, typo.

the line:

 // this just creates an error "cNode" has no properties
       cNode.insertData(0, String.fromCharCode(keycode));

should be:

 // this just creates an error "cNode" has no properties
       cNode.insertData(0, strText);
