komodo edit 是个挺好用的跨平台的编辑器。而且有很强大的扩展性。不仅有常规的运行外部程序功能，还能用javascript、python编写宏和扩展。

写程序的时候，常常需要测试一小段代码的结果。但是如果要先保存下来，再运行就有些麻烦了。就写了下面这个宏，只需要选定要运行的 php 代码，然后按一下快捷键，运行结果就会输出到 Command Output 面板中了。加了监听以后，还能中断运行。

dom 没 innerHTML 方法，直接 $dom->saveXML($node) 获取的相当于 outerHTML。所以得小折腾一下。

$e = $dom->getElementById('sample');
$content = '';
foreach ($e->childNodes as $node) {
    $content.= $dom->saveXML($node);
}
