Empty text nodes are still considered text nodes. That includes line breaks between tags. You should use getElementsByTagName() to get the element you want. You also need to access the text node once you have the element.

var book = xmlDoc.getElementsByTagName("book")[2]; // Get the book you're looking for (number 2 in the list)var authors = book.getElementsByTagName("author"); // Get a list of authors of the book.var a = authors[3]; // The author you want is number 3 on the listvar name = a.firstChild; // The name is the textnode contained in the <author> elementdocument.write(a.nodeValue);

Because I told it to write a.nodeValue instead of name.nodeValue. A simple mistake, you should look through the code and try to find these kind of mistakes yourself. It's important to understand the code instead of just copying and pasting.

I tested this code on that page and it works fine:

var book = xmlDoc.getElementsByTagName("book")[2]; // Get the book you're looking for (number 2 in the list)var authors = book.getElementsByTagName("author"); // Get a list of authors of the book.var a = authors[3]; // The author you want is number 3 on the listvar name = a.firstChild; // The name is the textnode contained in the <author> elementdocument.write(name.nodeValue);
