Check if the node value exist

I want to check in a xml if there is a node with the value "Hotel Hafen Hamburg".

But I get the error.

SimpleXMLElement::xpath(): Invalid predicate on line 25

You can view the xml here.

Until now I have written the following code.

$apiUmgebungUrl = "xml.xml";
$xml_umgebung = simplexml_load_file($apiUmgebungUrl);
echo $nameexist = $xml_umgebung->xpath('boolean(//result/name[@Hotel Hafen Hamburg');

It seems that your parantheses and brackets do not close properly at the end of your XPath expression - it should end on ]).

Also, what is Hotel Hafen Hamburg? If it is an attribute called value, your value check should look like this:

[@value="Hotel Hafen Hamburg"]

You cannot just write @ and then a value, without specifying where that value is supposed to be.

EDIT: Looking at the Xml document, it seems that Hotel Hafen Hamburg is supposed to be the text content of the <name> element. Therefore, try looking for a text node with that value rather than an attribute:

boolean(//result/name[text() = "Hotel Hafen Hamburg"])
