有人可以解释一下吗?
foreach ($xml as $product) {
为什么这会删除节点
unset ($product->itemspecific);
unset ($product->properties);
但这不会删除整个元素吗?
unset ($product);
}
修改
$result = $soap->GetFeedXML( array('accessKey' => $feed) );
//Write XML data to file
$bytes = file_put_contents($file,$result->GetFeedXMLResult);
$xml = new SimpleXMLElement($result->GetFeedXMLResult);
foreach ($xml as $product) {
//Remove fluous properties
unset ($product->ebay_itemspecific);
unset ($product->StoneProperties);
unset ($product->StoneValues);
unset ($product->UserCity);
unset ($product->eBayStartingPrice);
unset ($product->ebay_quantity);
unset ($product->ebay_variation);
unset ($product->Amazon_Metal_Type);
unset ($product->Amazon_Item_Type);
unset ($product->Ebay_Category_Number);
unset ($product->DropshipUser_Zip);
unset ($product->DropshipUser_Company);
unset ($product->PayPal_Email_Address);
//Convert different product sizes into options for the single product
$x = strpos($product->StockNo,"-");
if ($x > 0) {
$stock = substr($product->StockNo,0,$x);
$size = substr($product->StockNo,$x+1);
//Find the parent
$p = $xml->xpath("ProductFeedEntity[StockNo='$stock']");
$option = $p[0]->addChild("Options")->addChild("Size");
$option->addChild("Name","Size");
$option->addChild("Value", $size);
$option->addChild("CostPrice", $product->CostPrice);
echo "<i> Added size: " . $size . "</i><br>";
这就是问题所在。我已尝试使用$ index而没有。我尝试过未设置($ xml [$ index]),但这也不起作用。
//Remove the sized product
unset($product[$index]);
} else
echo $product->StockNo . " - " . $product->ItemTitle . "<br>";
$index++;
}
$xml->asXml($file);
XML
<ProductFeedEntity>
<StockNo>123</StockNo>
<MoreNodes>XXX</MoreNodes>
<MoreNodes>XXX</MoreNodes>
</ProductFeedEntity>
<ProductFeedEntity>
<StockNo>456</StockNo>
<MoreNodes>XXX</MoreNodes>
<MoreNodes>XXX</MoreNodes>
</ProductFeedEntity>
<ProductFeedEntity>
<StockNo>456-A</StockNo>
<MoreNodes>XXX</MoreNodes>
<MoreNodes>XXX</MoreNodes>
</ProductFeedEntity>
<ProductFeedEntity>
<StockNo>789</StockNo>
<MoreNodes>XXX</MoreNodes>
<MoreNodes>XXX</MoreNodes>
</ProductFeedEntity>
答案 0 :(得分:0)
您正在迭代一个对象(SimpleXMLElement
),因此您应该使用正确的语法来取消SimpleXMLElement
中的元素设置。
试试这个:
foreach($xml as $key => $product) {
// ...
unset($xml->$key);
}
从您的示例中可以看出,当您使用$index++
时,您正在生成密钥。 foreach
提供了在循环中获取数组键的功能,因此您应该尝试使用它。
