Hi Gordon,

Can use below for-each loop to get you started

<xsl:for-each select="umbraco.library:GetMedia($startNode, true())/node">...</xsl:for-each>

(Be aware though that it's querying the db quite heavily for each media item...)

Also have a look at cultiv's media caching package (can be found in the project section)

Cheers,

/Dirk

See the attached xslt file for a big step in the right direction.  It could be cleaned up a lot and it currently relies on a media picker on the page to select a download folder, but it could be easily adapted to use macro parameters.

Sorry I don't have much time to explain further!  These macros will create a nice list of documents with tags and file descriptions, filesize indicator and a an option to limit the list by tags.  It's probably a bit of overkill but a good start nonetheless
