How to parse this XML(XBRL) using Php

问题

I am new to PHP and I need to parse an XML file, make some changes in it and write it.

The file looks like this:

I have tried DOM parser using some example, But i can't parse fields like :

<pyde.02.00:AddressDetails.Postcode.Text>

Let me know if any other information is required.

Use Following code:

       $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;
            }

Using following code I am Able to read a value using specific query

If you load the data using something like simplexml_load_string then the following will do the job...

    $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);
}

You will need to add in the rest of the XML document, but this is just to show the main code as opposed to re-listing the whole xml. The main thing is the XPath, which you can see has the namespace (pyde.02.00) as well as the elements name to locate the particular bit your after. You should then be able to process these elements with your own code.

Edit: To modify values, you need to change the corresponding part of the element. So above prints out...

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

    [0] => 3350
)

So if in the code you do

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

This results in the element now being

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

    [0] => 3351
)

If you want to save this to a file, then

$xml->asXml( $fileName );
