Can I include an element from an xml file with php?

I have a list, consisting of links looking like this:

<a href=index.php?p=page_1>Page 1</a>
<a href=index.php?p=page_2>Page 2</a>
<a href=index.php?p=page_3>Page 3</a>

When clicked they include a page (page_1.inc.php or page_2.inc.php or page_3.inc.php) on my page thanks to this script:

<?php
  $pages_dir = 'pages';

  if(!empty($_GET['p'])){
      $pages = scandir($pages_dir, 0);
      unset($pages[0], $pages[1]);

      $p = $_GET['p'];

      if (in_array($p.'.inc.php', $pages)){
          include ($pages_dir.'/'.$p.'.inc.php');
      }
      else {
          echo 'Sorry, could not find the page!';
      }

  else {
      include($pages_dir.'/home.inc.php');
  }
?>

Period.

I also have an xml file looking like this:

<program>
    <item>
        <date>27/8</date>
        <title>Page 1</title>
        <info>This is info text</info>
    </item>
    <item>
        <date>3/9</date>
        <title>Page 2</title>
        <info>This is info text again</info>
    </item>
    <item>
        <date>10/9</date>
        <title>Page 3</title>
        <info>This just some info</info>
    </item>
</program>

This is what I want to achieve:

If I click on the link "Page 1" it will display "This is info text" on the page.

If I click on the link "Page 2" it will display "This is info text again" on the page.

If I click on the link "Page 3" it will display "This just some info" on the page.

Was I clear enough? Is there any solution for this?

You should be able to do this with SimpleXMLElement using the xpath() method.

$xmlString = file_get_contents("path/to/xml/file.xml");
$xml = new SimpleXMLElement($xmlString);
$info = $xml->xpath("/program/item[title='Page " . $page . "']/info");
echo (string) $info[0];

Update:

To get an array of all dates you would do something like this:

$xmlString = file_get_contents("path/to/xml/file.xml");
$xml = new SimpleXMLElement($xmlString);
$results = $xml->xpath("/program/item/date");

$dates = array();
if (!empty($results)) {
    foreach ($results as $date) {
        array_push($dates, (string) $date); // It's important to typecast from SimpleXMLElement to string here
    }
}

Also, you could combine the logic, if needed, from the first and second examples. You can reuse the $xml object for multiple XPath queries.

If you need $dates to be unique, you can either add an in_array() check before doing the array_push() or you can use array_unique() after the foreach.
