運行此代碼時,我得到這個錯誤: Fatal error: Uncaught exception 'DOMException' with message 'Invalid Character Error' in test.php:29 Stack trace: #0 test.php(29): DOMDocument->createElement('1OhmStable', 'a') #1 {main} thrown in test.php on line 29
PHP無效字符錯誤
,從原始的XML文件中確實含有無效字符的節點,但因爲我是從節點剝離無效字符了,應該創建節點。我需要在原始XML文檔上做什麼類型的編碼?我需要解碼saveXML嗎?
function __cleanData($c)
{
return preg_replace("/[^A-Za-z0-9]/", "",$c);
}
$xml = new DOMDocument('1.0', 'UTF-8');
$xml->load('test.xml');
$xml->formatOutput = true;
$append = array();
foreach ($xml->getElementsByTagName('product') as $product)
{
foreach($product->getElementsByTagName('name') as $name)
{
$append[] = $name;
}
foreach ($append as $a)
{
$nodeName = __cleanData($a->textContent);
$element = $xml->createElement(htmlentities($nodeName) , 'a');
}
$product->removeChild($xml->getElementsByTagName('details')->item(0));
$product->appendChild($element);
}
$result = $xml->saveXML();
$file = "data.xml";
file_put_contents($file,$result);
這是原始的XML是什麼樣子:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="/v1/xsl/xml_pretty_printer.xsl" type="text/xsl"?>
<products>
<product>
<modelNumber>M100</modelNumber>
<itemId>1553725</itemId>
<details>
<detail>
<name>1 Ohm Stable</name>
<value>600 x 1</value>
</detail>
</details>
</product>
</products>
新的文件應該是這樣的:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="/v1/xsl/xml_pretty_printer.xsl" type="text/xsl"?>
<products>
<product>
<modelNumber>M100</modelNumber>
<itemId>1553725</itemId>
<1 Ohm Stable>
</1 Ohm Stable>
</product>
</products>
你就像在跟自己說話,XML在哪裏? – ajreal 2011-12-15 17:27:15
