reading the first value using simplexml

Question

I am using simplexml to read all the child nodes successfully. But how do I read the "NumCrds"?

<ACCOUNT NumCrds="1">
<ACCNO>some Bank</ACCNO>
<CURRCODE>CAD</CURRCODE>
<ACCTYPE>00</ACCTYPE>
</ACCOUNT>

I have read it somewhere in the PHP manual but I am unable to find it now.

$my_num_cards=$sxe->ACCOUNT['NumCrds']; 

This is printing the number 1 for all the records even if there are values like 2, 3 in the file.

Answer 1

Attributes can be accessed using array indexes:

$data = '<ACCOUNT NumCrds="1">
<ACCNO>some Bank</ACCNO>
<CURRCODE>CAD</CURRCODE>
<ACCTYPE>00</ACCTYPE>
</ACCOUNT>
';
$xml = new SimpleXMLElement($data);

// this outputs 1
echo $xml['NumCrds'];

It is also possible to use the SimpleXMLElement::attributes() function to returns a list of all of the attribute key/value pairs.

$attributes = $xml->attributes();
echo $attributes['NumCrds'];

Answer 2

Use either $attrs = $el->attributes(); echo $attrs['NumCrds'] or just echo $el['NumCrds']. Attributes are reflected as array elements, while sub-tags are reflected as object properties.

Answer 3

$my_num_cards=$item->attributes()->NumCrds; 

This is what I was looking for. Thanks for all your help.
