Treating XML file with PHP

Question

I have the following XML:

<offer categoryId="3588" id="154394195459775522">
    <offerName>
        CAMISETA DROP DEAD PRODUCTION – MASCULINA VERDE ESCURO
    </offerName>
    <links>
        <link url="http://links.lomadee.com/ls/d25zZjsyRHd2U1I3MzsyODY4NjE3OTswOzU3OTg7MDs1NzE0O0JSOzM7aHR0cCUzQSUyRiUyRnd3dy5jZW50YXVyby5jb20uYnIlMkZwcm9tb2NhbyUzRm5leHRVcmwlM0R0LXNoaXJ0LWRyb3AtZGVhZC1wcm9kdWN0aW9uLTcwMjE0MDE4LTgxODE2OC5odG1sJTI2dHlwZSUzRHBkcCUyNmlkJTNEODE4MTY4JTI2dXRtX3NvdXJjZSUzRExvbWFkZWUlMjZ1dG1fbWVkaXVtJTNEeG1sJTI2dXRtX2NhbXBhaWduJTNETG9tYWRlZS1Ta2F0ZS1DYW1pc2V0YS0tODE4MTY4LTg2JTI2b3JpZ2VtJTNETG9tYWRlZTswOzA-.html" type="offer"/>

    <price>
        <currency abbreviation="BRL"/>
        <value>49.9</value>
        <parcel>
            <value>24.95</value>
            <number>2</number>
            <interest>0.0</interest>
        </parcel>
    </price>
    <seller id="84" isTrustedStore="false" pagamentoDigital="false" advertiserId="5714" oneClickBuy="false" oneClickBuyValue="0" cpcDifferentiated="false">

        <thumbnail url="https://wwws.lomadee.com/programas/BR/5714/logo_185x140.png"/>
        <links>
            <link url="http://www.centauro.com.br" type="seller"/>
        </links>
    </seller>
    <startOffer>1969-12-31T21:00:00-03:00</startOffer>
    <endOffer>8994-08-17T04:12:55.807-03:00</endOffer>
    <category id="3588" isFinal="true">
        <thumbnail url="http://imagem.buscape.com.br/bp5/categorias/3588.jpg"/>
        <name>Shorts Esportivo</name>
    </category>
</offer>

I called xml, via php as follows:

 <?php 
$xml = simplexml_load_file('arquivo.xml');  
foreach ($xml as $details){
    echo "<href='" . $details->links ."'>" . $details->offerName . "</a><br >";
    echo $details->thumbnail . '<br >';
    echo "R$" . $details->price->value . '<br >';
    echo $details->price->parcel->value->number . '<br >';
    echo $details->seller->sellerName . '<br >';

    echo '<br >';
    }
?>

The problem is that it is showing only the title, without the link. It shows the value, without the splitting. It does not show the thumbnail.

According to the code above, it brings a blank result always in the first line.

Answer 1

Well, according to your XML, you are working with an offer, so when you use foreach to traverse XML, it will go through all the parent nodes of the main tag. So when you make the call, for example, "$Details->offerName", you will get a blank.

I advise you to read and call the elements individually this way:

<?php 
    $details = simplexml_load_file('arquivo.xml');  

    echo "<a href='" . $details->links[0]->link["url"] ."'>" . $details->offerName . "</a><br >";
    echo $details->thumbnail["url"] . '<br >';
    echo "R$" . $details->price->value . '<br >';
    echo $details->price->parcel->value->number . '<br >';
    echo $details->seller->sellerName . '<br >';
    echo '<br >';
?>

Answer 2

Pay attention when using XML. All your errors are related when trying to use elements the wrong way, without following the structure of your document.

Note also that some data is element attributes. You can access these attributes through an element array.

As noted also in the @casscarraro response, your foreach is iterating the children of offer. As your file has only one offer, the foreach is unnecessary.

---

1- To display the thumbnail, you must place the content inside the tag img and access the url attribute.

echo '<img src="' . $details->thumbnail["url"] . '">';

2 - $details->links is a group of links, the correct is to associate to the correct element

echo "<href='" . $details->links->link->["url"] ."'>"

3 - Again, you specified the wrong path in your xml to display the portion.

echo $details->price->parcel->number . '<br >';

4 - The link is not appearing because the link tag is incorrect, the a

echo "<a href='{$link_url}'> {$xml->offerName} </a><br >";

At the end the corrected code looks like this:

<?php

$xml = simplexml_load_file('arquivo.xml');

$link_url = $xml->links->link["url"];
$imagem_url = $xml->thumbnail["url"];

echo "<a href='{$link_url}'> {$xml->offerName} </a><br >";
echo "<img src='{$imagem_url}'><br >";
echo "R$ {$xml->price->value} <br >";
echo "{$xml->price->parcel->number}x de {$xml->price->parcel->value} <br >";
echo "{$xml->seller->sellerName} <br >";

echo "<br >";
