XML TO XML WITH XSLT

I have been receiving one file like this

<?xml version="1.0" encoding="utf-8"?>
<StudentDocument xmlns:sdtc="urn:sl7-org:sdtc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:hvhs="urn:hvhs:student-extensions" xmlns="urn:student-org:v3">
  <recordTarget>
    <StudentRole>
      <id root="22" extension="65478" />
    <id root="23" extension="777-22-333" />
    <id root="24" extension="33333333" />
        <addr use="RT">
        <streetAddressLine>Address1</streetAddressLine>
        <city>City</city>
        <state>ST</state>
        <postalCode>55555</postalCode>
        <country>XT</country>
      </addr>
        <telecom use="TE" value="tel:+17248468200" />
      <Student>
        <name>
          <family>john</family>
              <given>katey</given>
        </name>
      </Student>
      </StudentRoleRole>
</recordTarget>
</StudentDocument>

I want to generate formatted XML like the below by using XSLT. How do i write it in visual studio 2013?

<StudentResultData>
      <ROLLNUMBER>777-22-333</ROLLNUMBER>
      <Phone>7248468200</Phone>
      <firstname>John</firstname>
      <lastname>katey</lastname>
      <address1>Address1</address1>
      <city>City<city>
      <zip>55555</zip>
      <state>ST</state>
      <country>XT</country>
</StudentResultData>
