Question

Hi wonder if anyone could help me.

the first code below basically counted every XML record and outputted in a desired formatt

Old code

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://xxxxx');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$xml_string = curl_exec ($ch);
curl_close ($ch);

// parse data
$xml=simplexml_load_string($xml_string);

// fix to n slots, zero padded
$slots=6;
$counter = substr((string)(pow(10,$slots)+count($xml)),1,$slots);

for($c=0; $c<strlen($counter); $c++)
{
    echo("<span>".$counter[$c]."</span>");
}

Out put

<span>1</span><span>3</span><span>5</span><span>6</span><span>8</span><span>8</span>

this was all ok but now the XML feed has changed and is just outputting the below.

<Data>
    <Row>
        <Column name="cam" type="xs:int">000</Column>
        <Column name="camN" type="xs:string">hello</Column>
        <Column name="numer" type="xs:int">1</Column>
    </Row>
    <Row>
        <Column name="cam" type="xs:int">000</Column>
        <Column name="camN" type="xs:string">hello</Column>
        <Column name="numer" type="xs:int">985</Column>
    </Row>
    <Row>
        <Column name="cam" type="xs:int">000</Column>
        <Column name="camN" type="xs:string">hello</Column>
        <Column name="numer" type="xs:int">1</Column>
    </Row>      
</Data>

i need the same output to happen but not sure how i take the number value from each record + them togther and then output them making sure i have 6 charactures even if it ends up 000005 as a value

Cheers

Update

---

sorry i need to add the numer values together to get a totel so if the totel is 987 i need it to output:

<span>0</span><span>0</span><span>0</span><span>9</span><span>8</span><span>7</span>

You can use xpath to grab the nodes you want, like so:

$xml = simplexml_load_string( $xml);
$elements = $xml->xpath( "/Data/Row/Column[@name='numer']");
$sum = 0;
foreach( $elements as $el)
{
    $sum += $el[0];
}
echo $sum; // Prints 12660

Now, to get your desired output, pad the number with zeroes, split it into chunks of 1 character, and output it, like so:

$formatted = sprintf('%06d', $sum);
echo '<span>' . implode( '</span><span>', str_split( $formatted)) . '</span>';
