如何在构造XML数据时使用FOREACH？

List<String> data = Arrays.asList("item1", "item2", "item3");

StringBuilder xmlBuilder = new StringBuilder();
xmlBuilder.append("<root>");

for (String item : data) {
    xmlBuilder.append("<item>").append(item).append("</item>");
}

xmlBuilder.append("</root>");

String xmlData = xmlBuilder.toString();

import xml.etree.ElementTree as ET

data = ["item1", "item2", "item3"]

root = ET.Element("root")

for item in data:
    ET.SubElement(root, "item").text = item

xmlData = ET.tostring(root).decode()

$data = array("item1", "item2", "item3");

$xml = "<root>";

foreach ($data as $item) {
    $xml .= "<item>" . $item . "</item>";
}

$xml .= "</root>";

$xmlData = simplexml_load_string($xml);
