Retrieving children from XML with PHP

问题

Helle there, There is a post: https://stackoverflow.com/questions/5816786/counting-nodes-in-a-xml-file-using-php I have the same question, but instead of count, I want to echo it. I have this code in xml:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<Row>
    <ModeNumber>1</ModeNumber>
    <Mode>online</Mode>
</Row>
<Row>
    <ModeNumber>2</ModeNumber>
    <Mode>mmorpg</Mode>
</Row>

And this as PHP:

$xml = simplexml_load_file("include/gamemodes.xml");

foreach ($xml->Row->children() as $child)
{
    echo $child->getName(), ": ", $child, "<br>";
}

It only echo's the first row and none more, how can I make it to echo multiple rows, the result should be:

ModeNumber: 1
Mode: online
ModeNumber: 2
Mode: mmorpg

Sorry for my bad english.

回答1:

You are iterating over the children of the first Row element only. Try this instead:

/* Iterate over all 'Row' elements */
foreach ($xml->Row as $row) 
{
    /* For each 'Row' iterate over all children elements */
    foreach ($row as $child) 
    {
        printf("%s: %s\n", $child->getName(), $child);
    }
}
