Hi Danny,

You could also do this by using a .Net control. For example this:

http://thetagcloud.codeplex.com/

/RasB

I'va made a tag cloud (blogcumulus): http://blog.thoehler.com/2009/05/14/new-package-blogcumulus-v10-published

Just look into the code and modify as you want.

There are several ways of doing it but yes you can grab the querystring in xslt and process it.

I had a look at that tag cloud package a little while back and determined that while it could be done, it would require a fair bit of xslt work almost to the point of it being easier to simply write your own tagcloud in xslt from scratch

O hold on I'm not sure I understood the question.

Ok if you go to the results page simply put an xslt macro on there that searches your tags for umbraco and lists the ones that match the filter... If you install Tim Geyssens Blog4Umbraco from the package repository in umbraco you can see how it's done in there there's a good example of filtering on tags

The querystring of filter='' alone doesn't return the results but is only a parameter you use when querying the nodes. Yes you will need to implement the filter in the XSLT macro you are using to display the results.

You will need to use the tags library when getting the nodes to display, like :

<xsl:for-each select="tagsLib:getAllTagsInGroup('whatever')/tags/tag">

Thanks guys for helping me on the good road!

After 4 hours I made, I installed the Blog4umbraco and watched to the code. I had to search because first i get an error that it couldn't find the taglib (i installed the blog4umbraco on another testsite). Finaly i found out that i had to config the taglib in the xsltExtensions.config.

Then i used the code from Tim (blog4umbraco) and removed everything i didn't need.

So now it is looking like this:

1. Tagcloud.dll from Christoph Ertl

2. XSLT from Tim Geyssens

Maby someone can see if i did it right? But thanks guys for helping me!
