使用 PHP 解析 XML

我正在尝试使用 PHP 的 SimpleXML 解析职位提要。我以前只使用过 JSON，但在让解析器工作时遇到问题。这是一些示例数据：

<shrs>
    <rq url="http://api.simplyhired.com/a/jobs-api/xml_v2/q-comission">

        <si>0</si>
        <rpd>10</rpd>
        <tr>192</tr>
        <tv>146</tv>
        <em url=""/>
        <h>
            <kw pos="1"/>
        </h>
    </rq>

    </e>
        </r>
    </rs>
</shrs>

[etc]

我想将标签中的元数据检索到变量中，然后循环遍历每个作业结果来处理它。我怎样才能用 PHP 做到这一点？ （到目前为止我一直在使用 SimpleXML 函数）

节点作为对象属性进行访问，属性使用数组表示法。foreach让您可以迭代节点。您可以通过将节点转换为字符串来获取节点的内容。 （所以如果你使用echo这是暗示的）

$shrs = simplexml_load_string($xml);

foreach ($shrs->rs->r as $r)
{
    $jobTitle = $r->jt;
    $city = $r->loc['cty'];

    echo "There's an offer for $jobTitle in $city<br />\n";
}
