Read XML attribute

Question

I am reading an XML file with the command simplexml_load_file() which has the following structure:

<nfeProc xmlns="http://www.portalfiscal.inf.br/nfe" versao="2.00">
    <NFe></NFe>
</nfeProc>

How do I get the value of the attribute versao?

I tried the following code but it didn’t work

$xmlsimple=simplexml_load_file($_FILES['filexml']['tmp_name']);
echo $xmlsimple->nfeProc['versao'];

Answer 1

Try it like this:

echo $xmlsimple->attributes()['versao'];
