Filter code for IFTTT script to translate Dreamwidth RSS to Facebook

Filter.js

var initialHtml = Feed.newFeedItem.EntryContent;
var crlf = "<br>&nbsp;<br>";
var crlf2 = "<br>&nbsp;<br>&nbsp;<br>";

// These are the RegExp+replacement transformations we are going to do on the HTML:
var transforms = [
  // A DW userhead:
  ["<span style='white-space: nowrap;'><a href='(?:.*?)'><img src='(?:.*?)' alt='(?:.*?)' width='17' height='17' style='(?:.*?)' /></a><a href='https://(?:.*?).dreamwidth.org/'><b>(.*?)</b></a></span>", "@$1"],
  ["<p>(.*?)</p>", '$1' + crlf],
  ['<a href="(.*?)">(.*?)</a>', "$2 ($1)"],
  ['<em>(.*?)</em>', "*$1*"],
  ['<strong>(.*?)</strong>', "**$1**"],
  // We simply strip <ul>, and turn <li> into bullets:
  ['<ul>(.*?)</ul>', "$1"],
  ['<li>(.*?)</li>', "* $1" + crlf],
  // The dynamic comment-viewing thingy at the bottom doesn't work in Facebook, so just strip it:
  ['<br /><br /><img (?:.*?)/> comments', ""]
];
// Do the transformations. This is ugly and mutable, but we're stuck with vanilla JS:
var curText = initialHtml;
var curExp = new RegExp("");
transforms.forEach(function doOne(transform) {
  curExp = new RegExp(transform[0], "gi");
  curText = curText.replace(curExp, transform[1]);
});

var finalText = curText;
var textToPost =
    "== " + Feed.newFeedItem.EntryTitle + " ==" + crlf +
    finalText + crlf +
    "Original post: " + Feed.newFeedItem.EntryUrl;

Facebook.createStatusMessage.setMessage(textToPost);
