Does anyone use xmltree functions?

Hello, I am trying to read and translate a substation description from xml file to a matlab file. I have installed a XML parser (<http://www.artefact.tk/software/matlab/xml/>) and my code is almost done, but when I use the function find, it doesn't result index array that I expect.

I show an example of what happens:

example.xml

   <?xml version="1.0" ?> 
- 
- <!--  This is the first entry of our Address Book  --> 
- <entry lastModified="16-May-2013">
  <firstName test="testing" test3="testing3">John</firstName> 
  <lastName test2="testing2">Doh</lastName> 
- <address>
  <institute /> 
  <street>1, Avenue des Champs Elysees</street> 
  <zipCode>75000</zipCode> 
  <city>Paris</city> 
  <country>France</country> 
  </address>
  <phone>([phone]</phone> 
  <email>[e-mail]</email> 
  </entry>
- <entry lastModified="16-May-2013">
  <firstName test="testing" test3="testing3">John</firstName> 
  <lastName test2="testing2">Doh</lastName> 
- <address>
  <institute /> 
  <street>1, Avenue des Champs Elysees</street> 
  <zipCode>75000</zipCode> 
  <city>Paris</city> 
  <country>France</country> 
  </address>
  <phone>([phone]</phone> 
  <email>[e-mail]</email> 
  </entry>

Ok now I create the tree: tree=xmltree('example.xml')

If I want to know where 'entry' is:

i=find(t,/addressBook/entry') i=[3 22]

Now if I suppose that index is referred to the next line, index 3 is for the fourth line, and there is Entry; index 22 should be for the 23th line then, but there's not entry!

How can I get the right index of each tag that I look for?

thank you
