Question

我正在尝试使用PHP创建一个包含以下格式的XML文件：

<outfits>
    <outfit>
        <head url="xxx" c="000" c2="000" z="1" />
    </outfit>
</outfits>

但我很困惑如何将多个值添加到字符串行，如url，c，c2，z。

// Function to create the outfit xml file
function create_outfit_xml(){
    $xml = new DomDocument('1.0', 'UTF-8');
    $outfits = $xml->createElement('outfits');
    $outfits = $xml->appenChild($outfits);
    $outfit = $xml->createElement('outfit');
    $outfit = $xml->appenChild($outfit);
}

我将如何创建这个？

Answer 1

虽然使用DOM是＆＃34;正确的＆＃34;做到这一点的方式，DOM也是臀部的一个彻头彻尾的痛苦，并且是一种令人难以置信的生成XML的方式。如果你有简单的XML，而且你知道如何安全地生成它，那就把它当作一个字符串来对待你的生活更轻松：

$url = htmlspecialchars($url);
$c = htmlspecialchars($c);

$xml = <<<EOL
<outfits><outfit><head url="$url" c="$c" etc... /></outfit></outfits>
EOL;

Answer 2

您可以创建属性。

$domAttribute = $xml->createAttribute('c');
$domAttribute->value = '200';
$domElement->appendChild($element);

在这种情况下，使用SimpleXMLElement类非常理想。以下是一个例子：

<?php

    function createOutfitXML(){
        $xml        = new SimpleXMLElement('<outfits></outfits>');
        $head       = $xml->addChild("head");
        $head->addAttribute("uri", "xxx");
        $head->addAttribute("c1", "000");
        $head->addAttribute("c2", "2");
        $head->addAttribute("z", "1");
        $outfit     = $xml->addChild("outfit", "jeans");
        $outfit->addAttribute("color", "red");
        $outfit->addAttribute("size", "32");
        $xml->asXML(__DIR__ . "/xml.xml");
    }
    createOutfitXML();

现在，假设您有一个包含要使用上述函数转换为XML文档的Outfits列表的数组。以下是使用函数的方法：

THE OUTFITS ARRAY：

<?php

    $outfitsArray   = [
        "jeans" => [
            [
                "size"  => '32',
                "color" => 'Dark Blue',
                "price" => 120.00,
                "brand" => 'Lee',
            ],
            [
                "size"  => '34',
                "color" => 'Black',
                "price" => 100.00,
                "brand" => 'Sean Jean',
            ],
            [
                "size"  => '30',
                "color" => 'White',
                "price" => 150.00,
                "brand" => 'Pepe',
            ],
        ],
        "shoes" => [
            [
                "size"  => '40',
                "color" => 'Black',
                "price" => 180.00,
                "brand" => 'Lee',
            ],
            [
                "size"  => '44',
                "color" => 'Brown',
                "price" => 200.00,
                "brand" => 'Sean Jean',
            ],
            [
                "size"  => '42',
                "color" => 'Dark Red',
                "price" => 240.00,
                "brand" => 'Versace',
            ],
        ]
    ];

算法：

<?php
    function createOutfitXML($outfitsArray){
        $xml        = new SimpleXMLElement('<outfits></outfits>');
        $head       = $xml->addChild("head");
        $head->addAttribute("uri", "xxx");
        $head->addAttribute("c1", "000");
        $head->addAttribute("c2", "2");
        $head->addAttribute("z", "1");
        foreach($outfitsArray as $groupName=>$itemData){
            foreach($itemData as $k=>$v){
                $outfit     = $xml->addChild("outfit");
                $outfit->addAttribute("group", $groupName);
                foreach($v as $key=>$value){
                    $outfit->addAttribute($key, $value);
                }
            }
        }
        $xml->asXML(__DIR__ . "/xml.xml");
    }
    createOutfitXML($outfitsArray);

上面的代码将创建一个类似于内容的XML文档：

    <?xml version="1.0"?>
    <outfits>
        <head uri="xxx" c1="000" c2="2" z="1"/>
        <outfit group="jeans" size="32" color="Dark Blue" price="120" brand="Lee"/>
        <outfit group="jeans" size="34" color="Black" price="100" brand="Sean Jean"/>
        <outfit group="jeans" size="30" color="White" price="150" brand="Pepe"/>
        <outfit group="shoes" size="40" color="Black" price="180" brand="Lee"/>
        <outfit group="shoes" size="44" color="Brown" price="200" brand="Sean Jean"/>
        <outfit group="shoes" size="42" color="Dark Red" price="240" brand="Versace"/>
    </outfits>
