这是我的product.xml文件：

<products>
    <product_id value="1">
        <tab_id>
            <tab_name value="test1" />
            <dist_region value="4909"/>
            <dist_region value="4909"/>
            <dist_region value="4909"/>
        </tab_id>
    </product_id>
</products>

解释

  1. 在general.xml文件中有一个名为 的节点元素<name>，它是一个store-city名称。
  2. 检查该城市名称是否存在于region.xml文件中，复制对应entity_id的 .
  3. 检查文件中是否entity_id存在，如果存在则product.xml返回相应的product_id。

例如：

  • <name>Rajkot</name>取自_general.xml
  • Rajkot存在于region.xml且对应entity_id的是4909
  • entity_id值4909存在于product.xml且对应的product_id属性值为1
  • 返回product_id值1

使用 PHP simplexml 执行此操作：--> 查看实时演示：http ://codepad.viper-7.com/ax2LtQ

// $g holds general.xml, $r region.xml, $p product.xml 

$general = simplexml_load_string($g);
$region = simplexml_load_string($r);
$product = simplexml_load_string($p);

$name = (string)$general->result->name;
$name = 'Rajkot' // <--- see explanation below!

if (strlen(trim($name))==0) exit('name not found');

list($entity) = $region->xpath("//*[@value='$name']/@entity_id");
$entity=(string)$entity;

if (strlen(trim($entity))==0) exit('entity_id not found');

list($prid) = $product->xpath("//dist_region[@value='$entity']/ancestor::product_id/@value");
$prid=(string)$prid;

echo "name: $name, entity_id: $entity, product_id: $prid";

解释： in general.xml, <name>= Rājkot, in region.xmlit's Rajkot, 没有特殊a字符。为了使代码正常工作，我必须设置$name为Rajkot.
您需要为此找到解决方案。
