解析和运行Javascript网页的Javascript引擎（perl/python）
我一直在尝试用Python（2.4）解析和运行JavaScript网页。可惜的是，我不能使用qt和webkit，所以大多数基于Python的无头浏览器都不能用了。不过，我最近发现了一个叫WWW::Scripter的Perl库（我用的是Perl 5.8.8），它似乎也可以用来运行JavaScript。我还安装了运行它所需的JavaScript插件。
use WWW::Scripter;
$w = new WWW::Scripter;
$w->use_plugin('JavaScript'); # packaged separately
$w->get('some javascript website');
print $w->content;
但是它打印了很多错误信息，最后就停止了，输出的结果和我预期的完全不一样。我试了3到4个网站，结果都是一样的。这里说的预期输出是指在谷歌浏览器中通过“检查元素”看到的源代码。
我想知道我在使用Perl脚本时哪里出错了？另外，有没有什么快速的方法可以在Python 2.4或Perl（甚至Ruby）中运行JavaScript引擎来解析这些网站？我不能使用qt。
希望我能清楚地表达我的问题，而不让人感到困惑。
