Module development and code questions

I was having trouble installing the ecommerece module because I could not see everything. So i installed the Sitemap module to help locate things. What a mistake that was. I did not back up my db because there was no mySQL involved I thought. But Site map destroys the default menu block by reseting it and removing all top level links. removall and Clearing the cache after does not fix this. The nav menus are in perfect alphabetical order and locked without header links to give any indication of what section they belong to.

Does anyone know how to get back the original?

In many of the drupal SQL calls I see something like:

SELECT n.created, n.title, n.nid, n.changed
    FROM node n
    WHERE n.status = 1
    ORDER BY n.created
    DESC ", 0, 10);

What do all the n. before the database feilds and names mean? This is pretty hard to search for as I don't know if this is a SQL thing, a PHP thing, or Drupal thing. And no search engine I can find will include the . in the search. Any help would be appreciated.

Hi,

It's been suggested writing a docBook module using XSLT to transfer XML into HTML, would be a good example of my application development skills. Are there creation guidelines I should follow?

I post media such as audio and video on my site and want to simplyfy the process by using bbcode. I would like to have a media tag that embeds the media player for me.

like [video]www.example.com/examplecss.wmv[/video]

what do I need to modify to get these extra media tags.

I need patch giving functionaliti plural choice when voting, rather then only radio.

Who did such?

I'm getting ready to install Flexinode.module and I see there have been several patches to this module.

At the top and in actual file there is this line:
"// $Id: flexinode.module,v 1.36.2.4 2005/02/06 18:20:26 killes Exp $'

does this mean that the file has been updated to include all patches up to 2005/02/06 by killes -- even though on the Flexinode Download page it says this:

"Download latest release (4.5.0, 24/09/2004 - 15:20)"

If wrong guess, please share what it means
