从SimpleXML对象中提取属性

Question

How do I extract attributes from this xml object

<designs>
    <tags>
    .
    .
    .
    </tags>
    <templates>
        <template id="photographysite" image="http://example.com/en/previews/photographysitePreview434x326.jpg" name="Shutter" thumb="http://example.com/en/previews/photographysitePreview182x137.jpg">
            <tag>all</tag>
            <tag>featured</tag>
            <tag>personal</tag>
            <tag>portfolio</tag>
            <tag>photography</tag>
            <tag>business</tag>
        </template>
    </templates>
</designs>

If I consider each object as $template, then this syntax wont work.

foreach ($xmldoc->templates as $template) {
    $attributes = $template->attributes();
        echo '<img src="' . $attributes['thumb'] . '" />';
}

You can access individual attributes using the array notation, e.g.

foreach ($xmldoc->templates->template as $template) {
    echo '<img src="', $template['thumb'], '"/>';
}
