Question

I am trying to parse data from the XML below (I shortened the data a lot to give an example of what the data looks like).

For each attribute, I would need to store the data in a separate array.

XML File

<report>
    <title>Resolution Times (Jun 07 00:21)</title>
    <sets>
        <set>
            <legend>Solved in Less than 2 Hours</legend>
            <values>
                <value data="8702" date="2012-05-24"/>
                <value data="8741" date="2012-05-25"/>
                <value data="8741" date="2012-05-26"/>
                <value data="8741" date="2012-05-27"/>
            </values>
        </set>
        <set>
            <legend>Solved in Less than 24 Hours</legend>
            <values>
                <value data="36990" date="2012-05-24"/>
                <value data="37094" date="2012-05-25"/>
                <value data="37096" date="2012-05-26"/>
                <value data="37144" date="2012-05-27"/>
            </values>
        </set>
    </sets>
</report>

Below is some test code I am doing to try and read in the data. For testing purposes I am just printing out to see what data is actually pulled.

$verifyReport = new SimpleXMLElement('305262.xml', null, true);
$testing = $verifyReport->sets->set->values->value;

echo '<ol>';
foreach($testing as $data)
{
    echo '<li>',
    $data['data'].PHP_EOL;
    echo '</li>';
}

echo '</ol>';

$testing1 = $verifyReport->sets->sets->values->value;

echo '<ol>';
foreach($testing1 as $data2)
{
    echo '<li>',
    $data2['data'].PHP_EOL;
    echo '</li>';
}

echo '</ol>';

Below is out the output of the data

1. 8702
2. 8741
3. 8741
4. 8741

Warning: Invalid argument supplied for foreach() in 
/Applications/XAMPP/xamppfiles/htdocs/tango/test.php on line 23

I am able to pull in the first set (Solved in Less than 2 hours) ok, but when I try to pull the data from the second set (Solved in Less than 24 Hours), I get the above error.

Can anyone help correct this issue?

Answer 1

In the second block you have $testing1 = $verifyReport->sets->sets->values->value; So I guess the second sets has to be set instead. But anyway, why don’t you iterate over $verifyReport->sets and read the further values inside of your for loop?

new SimpleXMLElement('305262.xml', null, true);
foreach ($verifyReport->sets->set as $set) {
    echo '<ol>';
    foreach ($set->values->value as $data) {
        echo '<li>',
        $data['data'] . PHP_EOL;
        echo '</li>';
    }
    echo '</ol>';
}
