Question

我会创建一个函数（使用，深度...）来获取xml中的一些元素。我的循环问题是提取信息。

谢谢

示例：

  echo $IceCatByEan->getSpecByName('width'); // size
  echo $IceCatByEan->getSpecByName('depth'); // size
  echo $IceCatByEan->getSpecByName('dimension_type'); // mn, cm

ceCatByEan-＆GT; getSpecByName（＆＃39; DIMENSION_TYPE＆＃39）; // mn

功能

// specificationName (like with, depth, dimension_type)

public function getSpecByName($specificationName) {
   $xml = $this->getSearchProductEanXML();
   $spec_item = $xml->xpath("//ProductFeature");

   foreach ($spec_item as $feature) {
       ...
   }
   return $element;
}

阵列演示

[features] =＆gt;排列（ [44095] =＆gt;排列（ [name] =＆gt;包装宽度 [value] =＆gt; 2453.64 [sign] =＆gt;毫米 [pres_value] =＆gt; 2453.6毫米））

Answer 1

我检索单个值的方法是使用XPath并直接获取每个值。

<?php
error_reporting ( E_ALL );
ini_set ( 'display_errors', 1 );

$xml = simplexml_load_file("t1.xml");

$spec_item = $xml->xpath("//ProductFeature[Feature/Name/@Value='Width']/@Presentation_Value");
echo 'Width='.(string)$spec_item[0];

输出：

Width=2192 mm

这是简化的，因为我只有一个产品的数据（上面的例子），我刚刚检索了Presentation_Value属性。但希望这个概念很容易适应你的追求。

XPath的工作方式是寻找一个ProductFeature元素，该元素具有一个封闭的Name元素，其Value属性设置为＆＃39; Width＆＃39;。因此，它将Product Feature元素缩小到这些元素并返回Presentation_Value属性。
