在Php中循環遍歷元素和SimpleXmlElement的屬性

Question

<info id="12AB" conf="D4XD"> 
<cinfo code="CB">Consumer Business</cinfo> 
<cinfo code="EB">Enterprise Business</cinfo> 
</info> 

<info id="12AB" conf="D4XD"> 
<cinfo code="CB">Consumer Business</cinfo> 
<cinfo code="EB">Enterprise Business</cinfo> 
</info> 

如何循環訪問cInfo元素，以便讀取值，即消費者業務和屬性值，即CB？

$obj = new SimpleXMLElement($xmldata); 
    foreach ($obj->children() as $cinfos) { 
????? 



    } 

Answer 1

This應該這樣做：

$obj = new SimpleXMLElement($xml); 

foreach ($obj->cinfo as $cinfos) { 
    // This is the value 
    $val = $cinfos[0]; 
    echo $val."\r\n";; 
    // Iterate through the attributes 
    foreach($cinfos[0]->attributes() as $key => $val) { 
     echo $key,'="',$val,"\"\n"; 
    } 
}
