SQL query against a web page(or, advanced find)
Suppose I have a table. Now, I'm interested in Getting Useful Data Easily. This means I'd rather not drop it into Excel and go through contortions, nor somehow get it into CSV and then into a DB, and then into SQL. I'd like to be able to execute a SQL query directly against a table in HTML. Has anyone heard of a tool like this before? ...
Strange treatment of "plus" character (+) by Internet Explorer 7
This is really weird... When I open the following simple HTML document in Internet Explorer 7.0.5730.11 (on Windows Server 2003 Web Edition SP2) <html> <body> <p>+</p> </body> </html> it shows me a totally blank page. FWIW, this is just a trivial "repro" sample. In real HTML documents, I observed other, even more bizzarre effe...

Embedding html code in stored procedures
We seem to have a few developers here who think creating stored procedures that spit out HTML or Javascript code is a legitimate thing to do. In my mind this is the ultimate abuse of the separation of concerns model. Is doing something like this people have often seen people doing? ...
Make a scrollable element stay "at the bottom" while adding content.
I am building a utility page for a web app that I am working on. I have an element that I want to use as a "console" of sorts. I get entries for the console via Ajax calls (using prototype's Ajax.PeriodicalUpdater). The problem I'm having is that when I insert new lines to the bottom of the "console", the scrollbar stays in the initi...
Prevent long word to add horizontal scroll to html view
On Windows Mobile, I am displaying my output in HTML. This includes lots of user-generated strings. Occasionally there are situations where a really large string is part of the output that has no whitespaces or punctuation.

What is the best way to parse HTML from a Rich Text Editor in Perl?
Is there a Perl module out there that can take bad HTML (such as what is copied from Microsoft Word) and parse it into nicely formatted HTML? I have looked at HTML::Tidy, but it has gotten horrible reviews on CPAN. We have a custom legacy module that's basically a wrapper for the command line version of tidy (which seems to be pretty m...

Invoking javascript in iframe from parent page
Basically, I have an iframe embedded in a page and the iframe has some javascript routines I need to invoke from the parent page. Now the opposite is quite simple as you only need to call parent.functionName() but unfortunately I need exactly the opposite of that. Please note that my problem is not changing the source url of the iframe...

Given the following markup: <ul> <li>apple</li> <li class="highlight">orange</li> <li>pear</li> </ul> Both the ul's and the li's widths appear to be 100%.

Is it possible to simulate spacing between table cells such that vertical and horizontal spacing are different?
In CSS, you can specify the spacing between table cells using the border-spacing property of a table. However, this results in uniform spacing between columns and rows, and I am finding more situations where the designs I am using call for gaps between rows, but not columns, or visa versa. If I have a solid background, I can simulate s...
