Question

How my XML node structure works, is I have multiple children elements of parents that also occur multiple times. I am able to get to the children elements, but only the first one of each parent. I am also trying to insert the data in the children elements into MySQL. I just can’t seem to access any child element after the first one. When I echo count(), I’m able to get a total count of the children elements for each reoccurring parent, but I can’t seem to work with that data. Parsing XML is fairly new to me, and my PHP is a bit rusty, so please forgive me. What am I not getting?

Note: The data I’m concerned with is in the mt nodes. The immediate parent of the mt nodes is the mi node.

$string = file_get_contents('file1.xml');
$xml = new SimpleXMLElement($string);

foreach ($xml->md as $mt_tag) {
    if (isset($mt_tag->mi->mt)) {
        $query = "INSERT INTO xmlData(
                xml_data
                ) VALUES (
                '{$mt_tag->mi->mt}'
                )";
        mysql_query($query, $connection);
        echo count($mt_tag->mi->mt);
        echo "<br />";
    } else {
        echo "<p>Creation Failed.<p>";
        echo "<p>" . mysql_error() . "</p>";
    }
}

Youre missing a for loop on the mt nodes:

foreach ($xml->md as $md_tag) {
       if (isset($md_tag->mi->mt)) {

              foreach ($md_tag->mi->mt as $mt) {
                    //do something
              }
       }
}

Please make sure to change this which is inconsistent

foreach ($xml->md as $mt_tag) {

to

foreach ($xml->md as $md_tag) {
