Let's consider PhoneBook.xml:

<?xml version="1.0"?>
<pb:PhoneBook xmlns:pb="http://www.epam.com/com/PhoneBook" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.epam.com/com/PhoneBook PhoneBook.xsd">

 </pb:BookRecord>
 <pb:BookRecord>

  <pb:email>estetka@mail.ru</pb:email>
  <pb:phone>+380666464111</pb:phone>
 </pb:BookRecord>
</pb:PhoneBook>

xsd file PhoneBook.xsd:

</xsd:schema>

xsl file PhoneBook.xsl:
