用PHP解析XML，根据特定属性值打印标签值数组

Question

我有一个类似于这样的 XML 文件

<?xml version="1.0" encoding="UTF-8"?>
<Root fileType="hierarchy" schema_version="1.1.1">
    <group id="978407" subtype="Web Section">
        <attribute definition_id="1294" is_name="true" type="text">
            <data language="English" label="Web Section">3.6V Drill Drivers</data>
        </attribute>
        <group id="884622" subtype="Product">
            <attribute definition_id="11" is_name="true" is_identifier="true" type="text">
                <data language="English" label="Product Name">Bosch IXO IV Cordless Screwdriver 3.6V (1.5Ah)</data>
            </attribute>
            <attribute definition_id="15" type="text">
                <data language="English" label="Brand">Bosch</data>
            </attribute>
            <attribute definition_id="18" type="text">
                <data language="English" label="Model">IXO IV</data>
            </attribute>

我想解析它并提取诸如“Model”值之类的内容（为了清楚起见，该值将是“IXO IV”或“id”属性的值（978407 或 884622）。

我希望使用 foreach 循环并将值添加到 csv 来完成此操作。

到目前为止我的 PHP 看起来像这样

<?php

// xml source
$filexml='3-6v-drill-drivers.xml';

if (file_exists($filexml))
{
    // headers variable
    $headers = array("sku", "attribute_set_code", "categories","name", "description","short_description","weight","speed","model","url_key","image","additional_images","accessories","alternatives");

    //xml object var
    $drillData = simplexml_load_file($filexml) or die("Me no understand");

   

$products = $drillData->xpath('/Root/group/group[@subtype="Product"]/attribute[@*]');

    //create the file
    $fh = fopen("testtttt.csv", "w");

    //create headers
    fputcsv($fh, $headers);

    //iterate over object
    foreach ($products as $product)
    {

        $put_arr = array($product->data['label="Model"'],$product->data['label="Brand"']);

        fputcsv($fh, $put_arr);

    }
    fclose($fh);  
}

?>

它不起作用...我也尝试在循环中使用 xpath 定义它（$put_arr = array($product->xpath('/data/[@label="Brand"]')），也无济于事.

Answer 1

此 xpath 将在单个查询中获取请求的值

//group/@id | //group[@subtype="Product"]/attribute/data[@label="Model"]/text()'

id="978407"
ID=“884622”
IXO IV
