PHP processing complex xml data sample code

XML database is a data management system that supports operations such as storing and querying documents in XML (an application under the Standard Universal Markup Language) format. In the system, developers can query, export, and serialize XML documents in a specified format.

This article mainly introduces the method of PHP processing complex XML data, and analyzes PHP's related operation skills for reading, loading, traversing, and computing XML format data in the form of examples. Friends in need can refer to it. Next

<?php
$xml = <<< XML
<?xml version="1.0" encoding="utf-8"?>
<epp xmlns="urn:ietf:params:xml:ns:epp-1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:ietf:params:xml:ns:epp-1.0 epp-1.0.xsd">
 <response>
  <result code="1000">
   <msg>Command completed successfully</msg>
  </result>
  <resData>
   <domain:chkData xmlns:domain="urn:ietf:params:xml:ns:domain-1.0" xsi:schemaLocation="urn:ietf:params:xml:ns:domain-1.0 domain-1.0.xsd">

     <domain:name avail="0">qq.com</domain:name>

     <domain:name avail="1">baidu.com</domain:name>

XML;
$x = simplexml_load_string($xml);
echo intval($x->response->result["code"]), "\n";
echo strval($x->response->result->msg), "\n";
$ns = $x->response->resData->getNamespaces(true);
$cds = $x->response->resData->children($ns["domain"])->chkData->cd;
foreach ($cds as $key => $value) {
  echo intval($value->name->attributes()["avail"]), strval($value->name), strval($value->reason), "\n";
}
