NIST The "replaceData(offset,count,arg)" method raises an INDEX_SIZE_ERR DOMException if the specified offset is greater than the length of the string. Retrieve the character data of the last child of the first employee and invoke its "replaceData(offset,count,arg) method with offset=40 and count=3 and arg="ABC". It should raise the desired exception since the offset is greater than the length of the string. Mary Brady 2001-08-17
