Dropdown list box using data from XML file
Build a select list from XML data
When XML values are inserted into HTML, escape the option value and visible label for the HTML output context.
<?php
$xml = simplexml_load_file('file-xml-demo.xml');
if ($xml === false) {
exit('Unable to load XML.');
}
echo "<select name='student'>";
foreach ($xml->details as $student) {
$id = htmlspecialchars((string) $student->id, ENT_QUOTES, 'UTF-8');
$name = htmlspecialchars((string) $student->name, ENT_QUOTES, 'UTF-8');
echo "<option value=\"{$id}\">{$name}</option>";
}
echo '</select>';
?>
The examples below show additional XML structures, return values, and practical uses.
Demo of dropdown list using XML data
Here is the PHP Script to generate the dropdown list
<?php
$obj_xml = new SimpleXMLElement('file-xml-demo.xml', NULL, TRUE);
// Total number of elements present ///
//$total = $obj_xml->count(); // total number of elements for PHP 5.3 and above
$total =count($obj_xml->children()); // for < php 5.3 version
$str="<select name='student'>";
for($i=0; $i<$total; $i++) {
$str= $str . "<option value=".$obj_xml->details[$i]->id.">".$obj_xml->details[$i]->name. "</option>";
}
$str = $str. "</select>";
