用PHP解析XML

Question

我正在嘗試使用PHP的SimpleXML解析作業提要。 我之前只使用過JSON，並且在解析器工作時遇到了問題。 這是一些示例數據：

<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]

我想將標簽中的元數據檢索到變量中，然后遍歷每個作業結果來處理它。 我怎么能用PHP做到這一點？ （到目前為止，我一直在玩SimpleXML功能）

Answer 1

節點作為對象屬性訪問，屬性使用數組表示法。 foreach允許您遍歷節點。 您可以通過將節點轉換為字符串來獲取節點的內容。 （所以如果你使用echo暗示）

$shrs = simplexml_load_string($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";
}

Answer 2

試試SimpleXML： http ： //www.php.net/manual/en/book.simplexml.php

它會將您的XML解析為一個漂亮的對象。

編輯：這是如何使用它（假設你的xml存儲在變量$ xml中）：

$xmlObject = new SimpleXMLElement($xml);

// to retrieve "http://api.simplyhired.com/a/jobs-api/xml_v2/q-comission"
$url = $xmlObject->rq['url'];

// to retrieve "Comission Jobs"
$t = $xmlObject->rq->t;
...

希望能幫助到你。
