我已经查看了有关此主题的许多帖子,并尝试对我的代码进行调整,但似乎无法使其正常工作,非常感谢任何帮助。
如何更新 cen_inst_units_z_name 的值?
XML
<?xml version="1.0" encoding="UTF-8" ?>
<xfa:data xmlns:xfa="http://www.xfa.org/schema/xfa-data/1.0/">
<form1>
<cen_inst_units_z_name>Department of School</cen_inst_units_z_name>
</form1>
</xfa:data>
PHP
<?php
$doc = new DOMDocument();
$doc->load('52500_data.xml');
$xpath = new DOMXPath($doc);
$parent = $doc->getElementsByTagName('form1')->item(0);
$query = $xpath->query('cen_inst_units_z_name',$parent);
//Checked to make sure I was pulling the correct node
echo $query->item(0)->textContent;
$query->item(0)->nodeValue = 'Test123';
$doc->saveXML();
?>
