Update xml namespace with data from PHP form

In the example below, a PHP form updates the XML with the text entered in the field.

XML 文件 labela.xml：

   change1 change2

用于更改 XML 文件中的“change1”和“change2”的 PHP 表单

 formatOutput = true; $xml->preserveWhiteSpace = false; $xml->load("labela.xml"); //Get item Element $element = $xml->getElementsByTagName("person")->item(0); //Load child elements $name = $element->getElementsByTagName("name")->item(0); $comment = $element->getElementsByTagName("comment")->item(0); //Replace old elements with new $element->replaceChild($name, $name); $element->replaceChild($comment, $comment); ?> nodeValue = $_POST["namanya"]; $comment->nodeValue = $_POST["commentnya"]; htmlentities($xml->save("labela.xml")); } ?>  name  comment

如何使用 PHP 从下面的 XML 结构中提取并更新字符串change1 和change2？

       change1    change2         change3

提前感谢所有花时间提供帮助的人

I think the XML structure needs to be converted into an object

$xmlObject = new SimpleXMLElement($xmlString);

You can then access the property.

Ideally use XPath to extract data from XML. By doing the following you will get the results you want:

Load.php

xpath('//pt:data')[0][0] = $change1; $xml->xpath('//pt:data')[1][0] = $change2; $xml->xpath('//pt:data')[2][0] = $change3; $xml->asXML('new_complex_xml.xml');

Form.php
