XML parsing with PHP

Question

I am trying to parse food for tasks using PHP SimpleXML. I only used JSON before and I have problems with the parser. Here are some sample data:

<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>

[etc.]

I would like to get the metadata in tags in variables, and then loop through each result of the work for processing. How can I do this with PHP? (I already played with SimpleXML functions)

Answer 1

Access to nodes is carried out as object properties, attributes use array notation. foreachallows you to iterate over nodes. You can get the contents of a node by exposing it as a string. (therefore, if you use echo, this is implied)

$shrs = simplexml_load_string($xml);

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

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

Answer 2

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

XML .

: (, xml $xml):

$xmlObject = new SimpleXMLElement($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;
...
