如何使用 Php 解析这个 XML(XBRL)

Question

我是 PHP 新手，我需要解析一个 XML 文件，对其进行一些更改并编写它。

文件如下所示：

我已经使用一些示例尝试了 DOM 解析器，但我无法解析字段 喜欢：

<pyde.02.00:AddressDetails.Postcode.Text>

如果需要任何其他信息，请告诉我。

Answer 1

使用以下代码：

       $xmldoc = new DOMDocument();
            $xmldoc->load("myFile.xml");
            $xpath = new DOMXPath($xmldoc);
            $xpath->registerNamespace("xbrli",  "http://www.xbrl.org/2003/instance");
            $xpath->registerNamespace("pyde.02.00", "http://sbr.gov.au/icls/py/pyde/pyde.02.00.data");

            $organizationNameList = $xpath->query("/xbrli:xbrl/pyde.02.00:OrganisationNameDetails.OrganisationalName.Text[@contextRef='    Context_Duration_ReportingParty']");
            if($organizationNameList->length != 0){
                $orgNode = $organizationNameList->item(0);
                $orgName = $organizationNameList->length === 1 ? $organizationNameList->item(0)->nodeValue : null;
                echo $orgName;
            }

使用以下代码，我可以使用特定查询读取值

如果您使用 simplexml_load_string 之类的方式加载数据，那么以下内容将完成这项工作...

    $xml = simplexml_load_string( '
            <xbrli:xbrl xsi:schemaLocation="http://xbrl.org/2006/xbrldi http://www.xbrl.org/2006/xbrldi-2006.xsd"
                       ... 
            </xbrli:xbrl>
');


foreach($xml->xpath('//pyde.02.00:AddressDetails.Postcode.Text') as $postCode) {
    print_r($postCode);
}

您需要添加 XML 文档的其余部分，但这只是为了显示主要代码，而不是重新列出整个 xml。 最主要的是 XPath，您可以看到它具有命名空间 (pyde.02.00) 以及元素名称，用于定位您之后的特定位。然后，您应该能够使用自己的代码处理这些元素。

编辑： 要修改值，您需要更改元素的相应部分。所以上面打印出来...

SimpleXMLElement Object
(
    [@attributes] => Array
        (
            [contextRef] => Context_Duration_SuperFundMember
        )

    [0] => 3350
)

所以如果你在代码中这样做

$postCode = $xml->xpath('//pyde.02.00:AddressDetails.Postcode.Text')[0];
$postCode[0] = "3351";

这导致元素现在是

SimpleXMLElement Object
(
    [@attributes] => Array
        (
            [contextRef] => Context_Duration_SuperFundMember
        )

    [0] => 3351
)

如果你想把它保存到一个文件中，那么

$xml->asXml( $fileName );
