I have an XML file and I want to check with PHP if there are any duplicated entries and remove the unnecessary one. Im running through all trans-units, pushing the id into an array and check if the entry already exist in the array. But how can I remove the trans-unit if I find an already existing id?
My XLF and my PHP Code:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<xliff xmlns="urn:oasis:names:tc:xliff:document:1.2" version="1.2">
<file source-language="de" target-language="de" datatype="plaintext" original="messages" date="2018-08-24T14:49:31Z" product-name="test">
<header/>
<body>
<trans-unit id="test">
<source>123</source>
<target/>
</trans-unit>
<trans-unit id="test2">
<source>123</source>
<target/>
</trans-unit>
<trans-unit id="test2">
<source>123</source>
<target/>
</trans-unit>
<trans-unit id="test3">
<source>123</source>
<target/>
</trans-unit>
<trans-unit id="test4">
<source>123</source>
<target/>
</trans-unit>
</body>
</file>
</xliff>
function cleanUpXliffFile($file) {
$transUnitIds = [];
$xlif = simplexml_load_file($file);
$xlif->file['source-language'] = "de";
foreach($xlif->file->body->{'trans-unit'} as $item) {
$unit = $item->attributes()->id;
$transUnitId = $unit[0]->__toString();
if(in_array($transUnitId, $transUnitIds)) {
//DELETE THE CHILD
}
$transUnitIds[] = $transUnitId;
if (!isset($item->target)) {
$item->addChild("target");
}
if ($item->target->__toString() !== "") {
$item->source = (string)$item->target;
$item->target[0] = "";
}
}
$xlif->saveXML($file);
}
