我想更改节点值sfa：TIN并将xml保存在新文件中。如何在PHP中实现这一目标？我得到了示例但没有使用名称空间。

Answer 1

你可以这样做的一种方法是使用DOMDocument和DOMXPath并使用例如xpath表达式找到你的元素，它将在sfa命名空间中找到'TIN'元素。

/ftc:FATCA_OECD/ftc:FATCA/ftc:ReportingFI/sfa:TIN

要更新第一个找到的元素的值，您可以从query返回的DOMNodeList中获取第一个项目。

$doc = new DOMDocument();
$doc->loadXML($data);
$xpath = new DOMXPath($doc);
$res = $xpath->query("/ftc:FATCA_OECD/ftc:FATCA/ftc:ReportingFI/sfa:TIN");
if ($res->length > 0) {
    $res[0]->nodeValue = "test";
}
$doc->save("yourfilename.xml");

Demo

Answer 2

您可以使用DOMDocument::getElementsByTagNameNS：

使用以下解决方案

<?php
$dom = new DOMDocument();
$dom->load('old-file.xml');

//get all TIN nodes.
$nodesTIN = $dom->getElementsByTagNameNS('urn:oecd:ties:stffatcatypes:v2', 'TIN');

//check for existing TIN node.   
if (count($nodesTIN) === 1) {

    //update the first TIN node.
    $nodesTIN->item(0)->nodeValue = 'NEWVALUE_OF_TIN';
}

//save the file to a new one.
$dom->save('new-file.xml');
