現有的PHP代碼輸出XML節點時,只能輸出第一個同名節點內容"100". 請問怎樣才能輸出所有節點的內容呢?
現有代碼見下:
/* $xmlstring 原內容:
**
-
id*cn
100
101
102
103
105
**
*/
$xmldoc = new DOMDocument();
$xmldoc->loadXML($xmlstring);
$users = $xmldoc->getElementsByTagName('GetUserInfo');
foreach ($users as $user) {
$html .= 'outputCustomer:'.get_txt($user,'Customer').'
';
$html .= 'outputGeo:'.get_txt($user,'GeocallCLI').'
';
}
echo $html;
function get_txt($parent, $name) {
$nodes = $parent->getElementsByTagName($name);
return $nodes->item(0)->nodeValue;
}
?>
回複內容:

function get_txt($parent, $name) {
$nodes = $parent->getElementsByTagName($name);
return $nodes->item(0)->nodeValue;
}
?>
最後一行代碼
return $nodes->item(0)->nodeValue;
因為只返回item(0)
所以只看得到一個100
只需檢測$nodes的長度,迴圈輸出即可
代碼
id*cn100101102103105';$xmldoc = new DOMDocument();$xmldoc->loadXML($xmlstring);$users = $xmldoc->getElementsByTagName('GetUserInfo');$html = '';foreach ($users as $user) { $html .= get_txt($user, 'Customer') . ''; $html .= get_txt($user, 'GeocallCLI') . '';}echo $html;function get_txt($parent, $name){ $nodes = $parent->getElementsByTagName($name); $data = ''; for ($i = 0; $i < $nodes->length; $i++) { $data .= 'output' . $name . ':' . $nodes->item($i)->nodeValue . '
'; } return $data;}?>
可否程式碼範例,謝謝!
