    <p>I can't seem to find a question on SO about my particular problem, so forgive me if this has been asked before!</p> <p>Anyway, I'm writing a script to loop through a set of URL's and give me a list of unique urls with unique parameters.</p> <p>The trouble I'm having is actually comparing the parameters to eliminate multiple duplicates. It's a bit hard to explain, so some examples are probably in order:</p> <p>Say I have a list of URL's like this</p> <ul> <li>hxxp://www.somesite.com/page.php?id=3&amp;title=derp</li> <li>hxxp://www.somesite.com/page.php?id=4&amp;title=blah</li> <li>hxxp://www.somesite.com/page.php?id=3&amp;c=32&amp;title=thing</li> <li>hxxp://www.somesite.com/page.php?b=33&amp;id=3</li> </ul> <p>I have it parsing each URL into a list of lists, so eventually I have a list like this:</p> <pre><code>sort = [['id', 'title'], ['id', 'c', 'title'], ['b', 'id']] </code></pre> <p>I nee to figure out a way to give me just 2 lists in my list at that point:</p> <pre><code>new = [['id', 'c', 'title'], ['b', 'id']] </code></pre> <p>As of right now I've got a bit to sort it out a little, I know I'm close and I've been slamming my head against this for a couple days now :(. Any ideas?</p> <p>Thanks in advance! :)</p> <p>EDIT: Sorry for not being clear! This script is aimed at finding unique entry points for web applications post-spidering. Basically if a URL has 3 unique entry points</p> <pre><code>['id', 'c', 'title'] </code></pre> <p>I'd prefer that to the same link with 2 unique entry points, such as:</p> <pre><code>['id', 'title'] </code></pre> <p>So I need my new list of lists to eliminate the one with 2 and prefer the one with 3 ONLY if the smaller variables are in the larger set. If it's still unclear let me know, and thank you for the quick responses! :)</p>

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.
