Re: [CODE4LIB] Tool to highlight differences in two files
Hi Wilhelmina, you might want to take a look at the work of Myriam Ben Saad: http://www-poleia.lip6.fr/~bensaadm/. She has a few papers describing extending a vision-based page segmentation algorithm (VIPS) to support webpage change analysis (Vi-DIFF). Here's one such paper from 2010: http://www-poleia.lip6.fr/~bensaadm/DEXA2010.pdf. The algorithm detects both visual changes and changes in the DOM. Unfortunately, I haven't yet seen any links to tools or production code using the approach. ~Nicholas -- https://twitter.com/nullhandle

The absolute simplest way to do this would be to fire up a terminal (OSX/Linux) and: diff page1.html page2.html | less Unfortunately, this will also catch changes made in other markup, and may or may not be terribly readable.

Re: [CODE4LIB] Tool to highlight differences in two files
Hi, I'm not sure if you're really looking for a diff tool, so I'll just shout an answer to a question that I think you might be asking. I use a variation of the script posted here: http://stackoverflow.com/questions/1494488/watch-a-web-page-for-changes for watching a web page for changes. I mostly only ever use this for watching for new artifacts to appear in Maven Central (because refreshing a web page is pretty dull work).

Re: [CODE4LIB] Tool to highlight differences in two files
That helps a lot, because it's for websites which is what I want to compare. I am looking for changes in a site, and I have some archives, but tools for merging code are too labor intensive and don't give a good visual report that I can show to a supervisor. This is good moving forward, but doesn't cover historical pages. I was hoping for something where I could call up two pages and get a visual display of differences for the display version of html, not the code. -Wilhelmina On Tue, Apr 23, 2013 at 5:14 PM, Pottinger, Hardy J. pottinge...@missouri.edu wrote: Hi, I'm not sure if you're really looking for a diff tool, so I'll just shout an answer to a question that I think you might be asking.

Re: [CODE4LIB] Tool to highlight differences in two files
I'm a real newbie when it comes to such things, but what is the possibility of using AJAX to cycle through each version of a page? I'm guessing that dynamic elements in each of those pages might pose a problem (that I'll leave up to you coding experts to answer). If it's visuals you're really looking to get, it certainly would be a cool effect to have the pages fade in and out. And a timeline slider would be nice.

Re: [CODE4LIB] Tool to highlight differences in two files
Automating your favourite browser to load and screenshot each version and then using http://www.imagemagick.org/Usage/compare/ should work. Note that this will also catch the scenario where someone has changed the page by changing an image on the page. cheers stuart On 24/04/13 10:18, Wilhelmina Randtke wrote: That helps a lot, because it's for websites which is what I want to compare.
