XML and W3School

Hello fine folks!
I have been working on a XML project this morning.
So if you were ever wondering what hard spent educational money buys,
here is an excercise:

***also, I have updated this 3 times since 1st post since I have discoved incorrect syntax***
always keep checking!!!!

Teacher: "Go to http://www.w3schools.com/ and read the tutorial on XML. 
Then write (2) examples"
That's it!

I do have to say that the w3schools has helped me tremendously in the past with HTML and CSS,
so use it and embrace its resource.

Also, a good rule I have to pass along as well from another teacher referring to open/close tags:
"Tags are like butt cheeks. You need two of them or things get messy!"

Remember XML doesn't do anything, its just a way of describing your code
In XML pay close attention to elements and tag order,
you need to set up a sort of hierarchy.

Here is what I came up with,
this goes along with a custom database I am creating:

<?xml version="1.0" encoding="ISO-8859-1"?>
<pet_database>
<pets>
  <pet_id1000>
    <name>patches</name>
     <type>dog</type>
        <breed>german_shepherd</breed>
        <dob>2010-02-28</dob>
       <owner_id>15236</owner_id>
  </pet_id1000>
