我有以下 XML，我需要从中解析值。

<ads>
    <ad id="987654321">
        <price>
            <currency-iso-code>
                <value localized-label="£">GBP</value>
            </currency-iso-code>
            <amount>345</amount>
        </price>
        <price_frequency>
            <value>WEEKLY</value>
        </price_frequency>
        <title>This is the Title</title>
        <description>

            </category>
            <locations>
                <location id="10000392">

                <attribute localized-label="Number of beds" type="LONG" name="property_number_beds">
                    <value>1</value>
                </attribute>
                <attribute localized-label="Date available" type="DATETIME" name="available_date">

                <pictures>

                        <link rel="preview" href="http://domain.com/images/81.JPG">
                        <link rel="big" href="http://domain.com/images/79.JPG">
                        <link rel="thumb" href="http://domain.com/images/78.JPG">
                        <link rel="moreadsthumb" href="http://domain.com/images/77.JPG">
                    </picture>
                </pictures>
            </public_link>
        </features_active>
    </ad>
</ads>

我需要从这个 xml 中提取以下数据

标题、描述 - 很容易拉。完成它们

我还需要 public_link href 和带有 rel="thumb"的图片 href 链接

通过查看此处的大量帖子和 php 文档，我得出了类似的结论。

$ads = simplexml_load_string($xml);


foreach ($ads as $ad) {

    $item['price']      = $ad->price->amount;
    $item['title']      = $ad->title;

    $link = simplexml_load_string($ad->features_active->public_link);

    foreach($link->attributes() as $attr => $value) {
        if($attr == 'href'){
            $item['link'] = $value;

        }
    }

    $pics = simplexml_load_string($ad->features_active->public_link->pictures);

    foreach($pics->picture[0]->attributes() as $attr => $value) {
        if($attr == 'thumb'){
            $item['picture'] = $value;

        }
    }

    echo "<br><br>" . $item['price'];
    echo "<br>" . $item['title'];
    echo "<br>" . $item['link'];
    echo "<br>" . $item['picture'];

}

出于某种原因，它不想提取属性。谁能为此指出正确的方向？

最佳答案

为 XML 解析器尝试 PHP DOMDocument。请引用以下 URL 获取标签和属性值。

http://www.php.net/manual/en/domdocument.getelementsbytagname.php

$objDOM = new DOMDocument('1.0'); 
$objDOM->preserveWhiteSpace = false;
$objDOM->loadXML($xml);

关于php - XMLA解析获取多个属性，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18571609/
