Filter XMLs in a folder based on node value using xslt (MatLab)

I have a folder containing thousands of xml entries (and this will be updated every day) and what i want to do is to filter all these entries based on a specific node value. e.g.

Filename1.xml

<?xml version="1.0" encoding="utf-8"?>
<addresses>
   <address>
      <type>A</type> 
      <name>Joe</name>
      <street>Baker street 5</street>
   </address>
</addresses>

and Filename2.xml

<?xml version="1.0" encoding="utf-8"?>
<addresses>
   <address>
      <type>B</type> 
      <name>Mary</name>
      <street>Baker street 5</street>
   </address>
</addresses>

Is it possible with XSLT to filter and to take in a folder only entries which contain:

<type>A</type>

If i do this with MatLab xlst function i would expect that the output should be a string if

type == A else empty string.
