用PHP解析XML

我正在尝试使用PHP的SimpleXML解析作业供稿.我以前只使用过JSON,在解析器正常工作时遇到了问题.以下是一些示例数据：

<shrs>
    <rq url="http://api.simplyhired.com/a/jobs-api/xml_v2/q-comission">
        <t>Comission Jobs</t>
        <dt>2011-02-18T23:58:38Z</dt>
        <si>0</si>
        <rpd>10</rpd>
        <tr>192</tr>
        <tv>146</tv>
        <em url=""/>
        <h>
            <kw pos="1"/>
        </h>
    </rq>
    <rs>
        <r>
            <jt>Virtual Recruiter (IT) - Comission ...</jt>
            <cn url="">Remedy Intelligent Staffing</cn>
            <src url="http://api.simplyhired.com/a/job-details/view/jobkey-monster91949932/cjp-0/hits-192?aff_id=28700">Monster</src>
            <ty>organic</ty>
            <loc cty="buffalo" st="NY" postal="14211" county="" region="" country="US">buffalo, NY</loc>

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

[等等]

我想将标签中的元数据检索到变量中,然后遍历下每个作业结果进行处理.我该如何使用PHP？ (到目前为止,我一直在使用SimpleXML函数)

解决方法:

节点作为对象属性访问,属性使用数组表示法. foreach使您可以遍历节点.您可以通过将其转换为字符串来获取节点的内容. (因此,如果您使用echo,则暗含)

$shrs = simplexml_load_string($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";
}
