在Python或PHP中从Treenode创建XML

import xml.etree.ElementTree as ET

root = ET.Element("root")

child = ET.SubElement(root, "child")
child.text = "This is the content of the child element"

xml_str = ET.tostring(root, encoding="utf-8", method="xml")

import xml.etree.ElementTree as ET

root = ET.Element("root")

child = ET.SubElement(root, "child")
child.text = "This is the content of the child element"

xml_str = ET.tostring(root, encoding="utf-8", method="xml")
print(xml_str)

$xml = new SimpleXMLElement("<root></root>");

$child = $xml->addChild("child", "This is the content of the child element");

$xml_str = $xml->asXML();

$xml = new SimpleXMLElement("<root></root>");

$child = $xml->addChild("child", "This is the content of the child element");

$xml_str = $xml->asXML();
echo $xml_str;
