Question

I have an rss feed that I am reading into. I need to retrieve certain data from the field in this feed.

This is the example feed data :

<content:encoded><![CDATA[
    <b>When:</b><br />
    Weekly Event - Every Thursday: 1:30 PM to 3:30 PM (CT)<br /><br />
      <b>Where:</b><br />
      100 West Street<BR>2nd floor<BR>Gainesville<BR>
      <br>.....

How do I pull out the data for When: and Where: respectively? I attempted to use regex but I am unsure if I am not accessing the data correctly or if my regex expression is wrong. I’m not set on using regex.

This is my code:

    foreach ($x->channel->item as $event) {
    $eventCounter++;
    $rowColor = ($eventCounter % 2 == 0) ? '#FFFFFF' : '#F1F1F1';
    $content = $event->children('http://purl.org/rss/1.0/modules/content/');
    $contents = $content->encoded;
    echo '<tr style="background-color:' . $rowColor . '">';
    echo '<td>';
    //echo "<a id=buttonRed href='$event->link' title='$event->title' target='_blank'>" . $event->title . "</a>";
    echo "" . $event->title . "";
    echo '</td>';
    echo '<td>';
    $re = '%when\:\s*</b>\s*(.|\s)<br \/><br \/>$/i';
    if (preg_match($re, $contents, $matches)) {
        $date = $matches;
    }
    echo $date;
    echo '</td>';
    echo '<td>';
    $re = '/^When\:<\/b>()$/';
    if (preg_match($re, $contents, $matches)) {
        $location = $matches;
    }
    echo $location;
    echo '</td>';
    echo '<td>';
    echo "<a id=buttonRed href='$event->link' title='$event->title' target='_blank'>Click Here To Register</a>";
    echo '</td>';
    echo '</tr>';
}

The two $res are just my attempt to get the data out using different regex expressions. Let me know where I am going wrong. Thanks

The following should sort of get you there. (I wrote this from the top of my head and it does not exactly following your XML syntax. But you get the idea.)

<?php
$str = "<root><b>When:</b> whenwhen <b>Where:</b> wherewhere</root>";

$doc = new DOMDocument();
$doc->loadXML($str);

$when = $where = "";
$target = null;

foreach ($doc->documentElement->childNodes as $node) {
    if ($node->tagName == "b") {
        if (++$i == 1) {
            $target = &$when;
        } else {
            $target = &$where;
        }
    }

    if ($target !== null && $node->nodeType === XML_TEXT_NODE) {
        $target .= $node->nodeValue;
    }
}

var_dump($when, $where);
