Iterating over XML with simplexml_load_string

Question

I'm trying to retrieve data from an XML document that looks like:

<scores sport="soccer" updated="08.05.2018 09:39:42">
<category name="Argentina: Superliga" gid="1081" id="1081" file_group="argentina" iscup="False">
<matches date="May 08" formatted_date="08.05.2018">
<match status="FT" timer="" date="May 08" formatted_date="08.05.2018" time="00:15" commentary_available="argentina" venue="Estadio Brigadier General Estanislao López" v="60" static_id="2288469" fix_id="2172208" id="2442089">
<localteam name="Colon Santa FE" goals="0" id="5947"/>
<visitorteam name="River Plate" goals="0" id="6042"/>
<events>
<event type="yellowcard" minute="39" extra_min="" team="visitorteam" player="C. Mayada" result="" playerId="91623" assist="" assistid="" eventid="24420891"/>
<event type="yellowcard" minute="40" extra_min="" team="localteam" player="M. Fritzler" result="" playerId="14256" assist="" assistid="" eventid="24420892"/>
<event type="subst" minute="46" extra_min="" team="visitorteam" player="J. Quintero" result="" playerId="74510" assist="G. Martinez" assistid="51346" eventid="24420893"/>
<event type="subst" minute="63" extra_min="" team="visitorteam" player="L. Pratto" result="" playerId="17657" assist="R. Mora" assistid="55877" eventid="24420894"/>
<event type="subst" minute="63" extra_min="" team="localteam" player="N. Leguizamon" result="" playerId="443149" assist="C. Bernardi" assistid="186181" eventid="24420895"/>
<event type="subst" minute="70" extra_min="" team="localteam" player="P. Ledesma" result="" playerId="13875" assist="A. Bastia" assistid="15082" eventid="24420896"/>
<event type="subst" minute="73" extra_min="" team="visitorteam" player="R. Borre" result="" playerId="320836" assist="I. Scocco" assistid="15172" eventid="24420897"/>
<event type="subst" minute="82" extra_min="" team="localteam" player="L. Heredia" result="" playerId="337735" assist="A. Ruiz" assistid="189511" eventid="24420898"/>
<event type="yellowcard" minute="90" extra_min="1" team="visitorteam" player="R. Borre" result="" playerId="320836" assist="" assistid="" eventid="24420899"/>
</events>
<ht score="[0-0]"/>
<ft score="[0-0]"/>
</match>
</matches>
</category>
<category name="Argentina: Primera B Nacional - Promotion - Play Offs" gid="3899" id="1078" file_group="argentina" iscup="False">
<matches date="May 08" formatted_date="08.05.2018">
<match status="23:05" timer="" date="May 08" formatted_date="08.05.2018" time="23:05" commentary_available="" venue="" v="0" static_id="2369960" fix_id="2253925" id="2443571">
<localteam name="Almagro" goals="?" id="5900"/>
<visitorteam name="Agropecuario" goals="?" id="21385"/>
<events/>
<ht score=""/>
</match>
</matches>
</category>
</scores>

What I have tried so far:

$xml=simplexml_load_string($content);
//print_r($xml);
foreach ($xml->scores->category->matches->match as $value) {
    echo (string)$value;
}

Message I'm getting:

Notice: Trying to get property of non-object in C:\xampp\htdocs\proj\inc\get.php on line 23

Notice: Trying to get property of non-object in C:\xampp\htdocs\proj\inc\get.php on line 23

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\proj\inc\get.php on line 23

To be specific, I'm trying to extract what's inside the attributes like Date, team name, goals, etc.

Thank you in advance.

When you load an XML file using SimpleXML, the root element is the starting point for any access. So you don't need scores as this is $xml.

foreach ($xml->category->matches->match as $value) {
    echo (string)$value['status'];
}

This outputs the status element (FT) to show it's actually the <match> element.

Update: As Syscall mentioned, the structure of this XML would need something like...

foreach ($xml->category as $value1) {
    foreach ( $value1->matches->match as $value)    {
        echo (string)$value['status'];
    }
}

to fetch all of the <match> elements.

@Syscall, they can either do it as two loops as you say, or use XPath. It depends if they really want them all or something else.
