Question

I want to delete:

<Eng>yellow</Eng>
</newWord>
from:
<?xml version="1.0" encoding="UTF-8"?>
<xml>
<newWord>
<Heb>מילה ראשונה</Heb>
<Eng>first word</Eng>
</newWord>
<newWord>
<Heb>צהוב</Heb>
<Eng>yellow</Eng>
</newWord>
</xml>
so the output will be:
<?xml version="1.0" encoding="UTF-8"?>
<xml>
<newWord>
<Heb>מילה ראשונה</Heb>
<Eng>first word</Eng>
</newWord>
</xml>

Answer 1

Try this:
$searchString = 'yellow';
$xml = simplexml_load_file('./Dictionary_user.xml');
foreach($xml->children() as $child){
if($child->getName() == "newWord") {
if($child->Eng == $searchString){
$dom = dom_import_simplexml($child);
$dom->parentNode->removeChild($dom);
}
}
}
echo $xml->asXML();

On this line
if($searchString == $child['Eng']) {
You're trying to compare the body of the child node, but it doesn't convert to a string automatically. It's still a SimpleXMLElement object, so the comparison fails.
Try explicitly casting it to a string to get the body of the tag.
if($searchString == (string)$child['Eng']) {
