Примеры
Пример 1. Traversing all the entries of the table
<?php
$doc
= new
DOMDocument
;
$doc
->
load
(
'book.xml'
);
$items
=
$doc
->
getElementsByTagName
(
'entry'
);
for (
$i

0
;
$i

length
;
$i
++) {

item
(

Alternatively, you can use foreach, which is a much more convenient way:
<?php
foreach (
$items
as
$item
) {
echo
$item
->
nodeValue
.
"\n"
;
}
?>
