[dspace-tech] Harvesting single items (with bitstream) in DSpace

[euler]

Hi All,

I have a use case scenario in which I have to only harvest a specific item. 
I came across this post from SO: Harvesting single items with DSpace 
<http://stackoverflow.com/q/33346023/1919069>. His solution worked when I 
tried it, but in my case, I would like to have the bitstream included in 
the created ZIP file. Also, instead of using the default oai_dc 
metadataPrefix, I would like to use dim. Below is his solution in php code. 
Hope someone can point me how to modify his code to meet my requirements.

<?php 
// handle and harvest-string
$handle  = "1874/1506";
$harvest = 
"http://dspace.library.uu.nl/oai/request?verb=GetRecord&metadataPrefix=oai_dc&identifier=oai:dspace.library.uu.nl:";
 . $handle;

// get XML from source repository
$sxe = simplexml_load_file($harvest, "SimpleXMLElement");

// add namespace schema-urls
$sxe->registerXPathNamespace('oai_dc', 
'http://www.openarchives.org/OAI/2.0/oai_dc/');
$sxe->registerXPathNamespace('dc', 'http://purl.org/dc/elements/1.1/');

// get Dublin Core (dc) elements from the XML
foreach($sxe->xpath("//oai_dc:dc") as $entry) {
    $child = $entry->children('dc', true);
}

// add dc-elements (names and values) to array
foreach($child as $elementName => $elementValue) {$elements[$elementName][]  = 
$elementValue;}

// create zip-object and -file
$zip = new ZipArchive();
$zip->open("doc/importZip.zip", ZipArchive::CREATE);

// create a directory in the zip-object
$zip->addEmptyDir("item");

// create Dublin Core XML object
$oXML = new DOMDocument();
$oXML->encoding      = "UTF-8";
$oXML->formatOutput  = true;
$oXML->xmlStandalone = false;

$oRoot = $oXML->createElement('dublin_core');
$oRoot->setAttribute('schema', 'dc');
$oXML->appendChild($oRoot);

// add elements and their values to XML object
foreach($elements as $elementName => $elementValues) {
    foreach($elementValues as $elementValue) {
        $oDcValue = $oXML->createElement('dcvalue');
        $oDcValue->setAttribute('element', $elementName);
        $oText = $oXML->createTextNode($elementValue);
        $oDcValue->appendChild($oText);
        $oRoot->appendChild($oDcValue);
    }
}

// save created XML to string
$dublinCoreXml = $oXML->saveXML();

// add XML-string as file to zip-object
$zip->addFromString("item/1/dublin_core.xml", $dublinCoreXml);

// add handle as file to zip-object
$zip->addFromString("item/1/handle", $handle);

$zip->close();

?>


Thanks in advance,
euler
