如何将其转换为php输出？

<?xml version="1.0" encoding="iso-8859-1"?>    
    <employee>
          <name>Mark</name>
          <age>27</age>
          <salary>$5000</salary>
          </employee>
          <employee>
          <name>Jack</name>
          <age>25</age>
          <salary>$4000</salary>
          </employee>
          <employee>
          <name>nav</name>
          <age>25</age>
          <salary>$4000</salary>
    </employee>

Answer 1

<?php
$doc = new DOMDocument();
$doc->load( 'test1.xml' );//xml file loading here

$employees = $doc->getElementsByTagName( "employee" );
foreach( $employees as $employee )
{
  $names = $employee->getElementsByTagName( "name" );
  $name = $names->item(0)->nodeValue;

  $ages= $employee->getElementsByTagName( "age" );
  $age= $ages->item(0)->nodeValue;

  $salaries = $employee->getElementsByTagName( "salary" );
  $salary = $salaries->item(0)->nodeValue;

  echo "<b>$name - $age - $salary\n</b><br>";
  }
?> 

//像Mark这样的输出 - 27 - $ 5000 Jack - 25 - $ 4000 nav - 25 - $ 4000
