[英]Trying to edit an XML document with a dynamic variable from PHP
我正在嘗試使用PHP編輯XML文檔,但它似乎不起作用,想知道我哪里出錯了!
我試着按照以下方式在網上找到它。 有誰能告訴我正確的方向?
XML
<gold>
<coin>
<id>1</id>
<title>Gold Coin 50 Grams</title>
<price>500 rupees</price>
<dimension>20 MM</dimension>
<thumb_url>http://animsinc.com/Expertise-media.png</thumb_url>
</coin>
<coin>
<id>2</id>
<title>Gold Coin 50 Grams</title>
<price>500 rupees</price>
<dimension>20 MM</dimension>
<thumb_url>
http://animsinc.com/Expertise-media.png</thumb_url>
</coin>
...
</gold>
PHP代碼
$xmlDoc = new DOMDocument();
$xmlDoc->loadXml($str);
$events = $xmlDoc->getElementsByTagName("coin");
foreach($events as $event){
$eventNames = $event->getElementsByTagName("price");
$eventN = $eventNames->item(0)->nodeValue;
if('500' == $eventN){ // ** Failed here, instead of '500',
// I used '500 rupees' and it worked, as that matches the original text.**
$eventNames->item(0)->nodeValue = $rest ;
}
}
var_dump($xmlDoc->saveXML());
這是期望的結果。 請注意我如何將價格標簽更改為2495盧比。
<gold>
<coin>
<id>1</id>
<title>Gold Coin 50 Grams</title>
<price>2495 rupees</price>
<dimension>20 MM</dimension>

</gold>
哦,嘿,這是我的錯誤,功能完美,而不是
if('500' == $eventN)
正確的事實是
if('500 rupees' == $eventN)
啞
