Demonstrate the XML FindNextRecord Method

See more XML Examples

Imagine we have an XML file as follows:

<CompleteMultipartUpload>
  <Part>
    <PartNumber>1</PartNumber>
    <ETag>abc</ETag>
  </Part>
  <Part>
    <PartNumber>2</PartNumber>
    <ETag>def</ETag>
  </Part>
  <Part>
    <PartNumber>3</PartNumber>
    <ETag>ghi</ETag>
  </Part>
</CompleteMultipartUpload>

We want to find the record where PartNumber = 2. To do so, we simply position ourselves at the first "Part" tag, and then call FindNextRecord. (See below..) Chilkat2 PHP

<?php

use Chilkat2\Xml;

$xml = new Xml();

$xml->LoadXmlFile('qa_data/xml/multipartUpload.xml');

// Position ourselves at the 1st record.
$xml->GetChild2(0);

$foundRec = $xml->FindNextRecord('PartNumber', '2');
if ($foundRec !== null) {
    echo "Found the record where PartNumber = 2.\n";
    echo $foundRec->GetXml(), "\n";

    // Let's examine the ETag for this record...
    echo 'ETag for PartNumber 2 = ', $foundRec->GetChildContent('ETag'), "\n";
} else {
    echo "No record exists where PartNumber = 2.\n";
}

// What if we want to find the record where ETag = "abc"?
$foundRec = $xml->FindNextRecord('ETag', 'abc');
if ($foundRec !== null) {
    echo "Found the record where ETag = abc\n";
    echo $foundRec->GetXml(), "\n";

    // Let's examine the PartNumber for this record...
    echo 'Part number for Etag(abc) = ', $foundRec->GetChildContent('PartNumber'), "\n";
} else {
    echo "No record exists where ETag = abc.\n";
}

// Go back to the XML root..
$xml->GetRoot2();
