    <p>A description of what I'm going to accomplish: </p> <ul> <li>Input 2 (N is not essential) HTML documents. </li> <li>Standardize the HTML format</li> <li>Diff the two documents -- external styles are not important but anything inline to the document will be included. </li> <li>Determine delta at the HTML Block Element level. </li> </ul> <p>Expanding the last point: </p> <p>Imagine two pages of the same site that both share a sidebar with what was probably a common ancestor that has been copy/pasted. Each page has some minor changes to the sidebar. The diff will reveal these changes, then I can "walk up" the DOM to find the first common block element shared by them, or just default to <code>&lt;body&gt;</code>. In this case, I'd like to walk it up and find that, oh, they share a common <code>&lt;div id="sidebar"&gt;</code>. </p> <p>I'm familiar with DaisyDiff and the application is similar -- in the CMS world. </p> <p>I've also begun playing with the google diff-patch library. </p> <p>I wanted to give ask this kind of non-specific question to hopefully solicit any advise or guidance that anybody thinks could be helpful. Currently if you put a gun to my head and said "CODE IT" I'd rewrite DaisyDiff in Python and add-in this block-level logic. But I thought maybe there's a better way and the answers to <a href="https://stackoverflow.com/questions/31722/anyone-have-a-diff-algorithm-for-rendered-html">Anyone have a diff algorithm for rendered HTML?</a> made me feel warm and fuzzy. </p>

    2. COI'm not sure of your exact application but a DOM ranking algorithm is used by projects like http://www.readability.com/ to extract relevant content. If you want to diff only on the core of the page, something like that might make sense

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
