帮人搬家之导入Blogger

在跟我实在不熟的Python奋斗了若干时间后，我才悲哀地发现，Blogger现在对API导入添加了限制。每天通过API发布一定量的帖子后，再发就得输入验证码，我太阳。

还好，通过尝试发现，Blogger GUI中提供的导入功能可以用。不然的话，某人的小500张帖子，还不知道要弄到什么时候去。

用Javascript写这段代码，看起来就乱七八糟的。不过没办法，还是因为Ruby没有好用的HTMLParser。虽然可以在Ruby里可以调用ActiveX COM，但是会有回车换行符混乱的问题，将就用吧。

// 这个函数用来处理内文需要修改的地方
// 如果没什么可改的那就不需要调用
function parseHTML(src) {
  var doc = new ActiveXObject('htmlfile');
  doc.write(src);
  
  var es = doc.getElementsByTagName('img');
  for (var i=0;i<es.length;i++) {
    var s = es[i].src;
    if (s.indexOf('foto.ycstatic.com')>0) {
      es[i].src = imgmap[encodeURIComponent(s)];
    }
  }
  return doc.body.innerHTML;
}

function parseXML(path) {
  var xml = new ActiveXObject('MSXML2.DOMDocument.3.0');
  xml.load(path);
