如何在PHP數組中分離HTML/XML標籤？

Question

我有一個數組，需要拆分參數。到目前爲止，我曾嘗試：

$test = array 
(
    'username' => 'vale', 
    'apiaccesskey' => 'myapi', 
    'action' => 'placeimeiorder', 
    'requestformat' => 'JSON', 
    'parameters' => '<PARAMETERS><CUSTOMFIELD>bnVsbA==</CUSTOMFIELD><ID>221</ID><IMEI>354443063506889</IMEI><MODELID></MODELID><PROVIDERID></PROVIDERID><NETWORK></NETWORK><PIN></PIN><KBH></KBH><MEP></MEP><PRD></PRD><TYPE></TYPE><LOCKS></LOCKS><REFERENCE></REFERENCE><SN></SN><SECRO></SECRO></PARAMETERS>', 

    'version' => '2.3.1' 
); 



$html = $test['parameters']; 
$doc = new DOMDocument(); 
$doc->loadHTML($html);  
$tags = $doc->getElementsByTagName('PARAMETERS');  
echo 'ID '.$tags->item(0)->getAttribute('ID').'" IMEI="'.$tags->item(0)->getAttribute('IMEI').'"/>'; 

作爲回報，我得到致命錯誤與此代碼，但它SeeME所它recognizong和分離標籤值，這就是希望。下面是錯誤日誌：

Warning: DOMDocument::loadHTML() [domdocument.loadhtml]: Tag id invalid in Entity, line: 1 in /test.php on line 24 

Warning: DOMDocument::loadHTML() [domdocument.loadhtml]: Tag imei invalid in Entity, line: 1 in /test.php on line 24 

Warning: DOMDocument::loadHTML() [domdocument.loadhtml]: Tag modelid invalid in Entity, line: 1 in /test.php on line 24 

Warning: DOMDocument::loadHTML() [domdocument.loadhtml]: Tag providerid invalid in Entity, line: 1 in /test.php on line 24 

....

我想在陣列輸出：

'CUSTOMFIELD' = 'bnVsbA==', 
'ID' = '221', 
'IMEI' = '354443063506889', 
'MODELID' = '', 
'PROVIDERID' = '', 
'NETWORK' = '', 
..so on.. 

所以我可以用echo $test['IMEI'];，它會輸出：

我該如何解決這個錯誤，並得到在$test['parameters']分離的所有標籤？

謝謝你的幫助。

Answer 1

$dom = new DOMDocument; 
libxml_use_internal_errors(true); 
$dom->loadHTML('...'); 
libxml_clear_errors(); 

要忽略警告，請使用libxml_use_internal_errors(true);之前loadHTML()功能。

Answer 2

看來parameters是XML，所以你應該使用loadXML功能，見下面的例子：

$test = array 
(
    'username' => 'vale', 
    'apiaccesskey' => 'myapi', 
    'action' => 'placeimeiorder', 
    'requestformat' => 'JSON', 
    'parameters' => '<PARAMETERS><CUSTOMFIELD>bnVsbA==</CUSTOMFIELD><ID>221</ID><IMEI>354443063506889</IMEI><MODELID></MODELID><PROVIDERID></PROVIDERID><NETWORK></NETWORK><PIN></PIN><KBH></KBH><MEP></MEP><PRD></PRD><TYPE></TYPE><LOCKS></LOCKS><REFERENCE></REFERENCE><SN></SN><SECRO></SECRO></PARAMETERS>', 

    'version' => '2.3.1' 
); 

$html = $test['parameters']; 
$doc = new DOMDocument(); 
$doc->loadXML($html); 
$tags = $doc->getElementsByTagName('ID'); 
$id = $tags->item(0)->nodeValue; 
$tags = $doc->getElementsByTagName('IMEI'); 
$imei = $tags->item(0)->nodeValue; 
echo 'ID="'.$id.'" , IMEI="'.$imei.'"'; 

爲了獲得陣列中的所有元素，你可以使用下面的解決方案：

$html = $test['parameters']; 
$doc = new DOMDocument(); 
$doc->loadXML($html); 
$tags = $doc->getElementsByTagName('PARAMETERS'); 

$root = $doc->documentElement; 
foreach($root->childNodes as $node){ 
    $attributes[$node->nodeName] = $node->nodeValue; 
} 

print_r($attributes);

這將做什麼你想:(完整的工作示例）

<?php 
$test = Array 
(
    'username' => 'vale', 
    'apiaccesskey' => 'myapi', 
    'action' => 'placeimeiorder', 
    'requestformat' => 'JSON', 
    'parameters' => '<PARAMETERS><CUSTOMFIELD>bnVsbA==</CUSTOMFIELD><ID>221</ID><IMEI>354443063506889</IMEI><MODELID></MODELID><PROVIDERID></PROVIDERID><NETWORK></NETWORK><PIN></PIN><KBH></KBH><MEP></MEP><PRD></PRD><TYPE></TYPE><LOCKS></LOCKS><REFERENCE></REFERENCE><SN></SN><SECRO></SECRO></PARAMETERS>', 

    'version' => '2.3.1' 
); 



$html = $test['parameters']; 
$doc = new DOMDocument(); 
$doc->loadXML($html);  
$p = $doc->getElementsByTagName('PARAMETERS')->item(0); 
$opts=array(); 
foreach($p->getElementsByTagName('*') as $item) 
{ 
    $opts[$item->nodeName]=$item->nodeValue; 
} 
echo '<pre>'.print_r($opts,true).'</pre>';
