 See the incomplete script "archive_crawler" to see my working.
 
-- TODO: Second crawl
-- TODO: Filter out all the non-markdown garbage.  It looks like everything up to `<div class="editBox" role="application">`, and everything after `</div><!-- /content --></div>` is a good first cull.

+## Extracting the markdown
+So the pages that have `'?do-edit'` on the end of their URL appear to have a reliable and predictable structure:
+
+```bash
+[ LINES ABOVE REMOVED FOR BREVITY ]
+    <div class="toolbar group">
+        <div id="draft__status" class="draft__status"></div>
+        <div id="tool__bar" class="tool__bar"></div>
+    </div>
+    <form id="dw__editform" method="post" action="" accept-charset="utf-8" class=" form-inline"><div class="no">
+<input type="hidden" name="sectok" value=""/><input type="hidden" name="id" value="wishes"/>[REST OF LINE REMOVED FOR BREVITY]
+
+[ TARGET MARKDOWN CODE EXISTS HERE]
+
+</textarea>
+<div id="wiki__editbar" class="editBar">
+<div id="size__ctl">
+</div>
+[ LINES BELOW REMOVED FOR BREVITY ]
+```
+
+So basically, we remove everything from the first line to the line that contains `name="sectok"`, and then we remove everything after `</textarea>`, and what's left should be the markdown that we want.
