XML manipulation with PHP

Question

I am creating a tool for reading XML files that will be searched locally in the user’s machine, I searched and found very easy methods to use in PHP, simpleXML.

I have the following code:

<?php 


    $arq = simplexml_load_file('29190411412201000112650010000000181000000180-nfe.xml') or die("Erro ao carregar arquivo XML");


    foreach ($arq->children() as $infNFe) {

        echo $infNFe->natOp;

        echo $infNFe->mod;

        echo $infNFe->tpNF;

        echo $infNFe->dhEmi;
    }

?>

It should return the values of these XML tags, but nothing happens on the page and if I give a var_dump in the variable that receives XML it is returned.

The XML I’m using is the 65 Nfce Model Sales.

I’ll leave the beginning of XML:

<nfeProc xmlns="http://www.portalfiscal.inf.br/nfe" versao="4.00">
<NFe xmlns="http://www.portalfiscal.inf.br/nfe">
<infNFe versao="4.00" Id="NFe29190411412201000112650010000000181000000180">

Gabriel the problem is that you’re looking for the information at the wrong level, this information is actually a few levels further in. Try it that way:

foreach ($arq->NFe->infNFe->children() as $infNFe) {
    echo $infNFe->natOp;

    echo $infNFe->mod;

    echo $infNFe->tpNF;

    echo $infNFe->dhEmi;
}
