PHP-da ichma-ich guruh XML teglari

Endi bizda bir nechta ichida ichma-ich teglar bo'lgan teglar mavjud:

test.xml<root>
  <tag>
    <elem>text1</elem>
  </tag>
  <tag>
    <elem>text2</elem>
  </tag>
  <tag>
    <elem>text3</elem>
  </tag>
</root>

Teglarimizni tsikl bilan aylantiramiz va ichma-ich teglarning qiymatlarini chiqaramiz:

index.php<?php
  foreach ($xml->tag as $tag) {
    echo $tag->elem; // 'text1', 'text2', 'text3'
  }
?>
