Hi i need some help, and question

instead of using parameters in xsl

i would like to use document properties to select rss feed

so i can change it easily threw the content section.

I hope this is possible

1. Select the node by node type or by nodeid

http://our.umbraco.org/wiki/reference/umbracolibrary/getxmlnodebyid-(1)

2. Get the property you want to use

You can also pass parameters to a macro:

http://our.umbraco.org/wiki/reference/templates/umbracomacro-element/macro-parameters

It might be worth your while digging through the Wiki as there is a lot of useful info on there.

Hope this helps.

not exactly what i mean i guess

this is my xslt

i changed number of items and feed url, so it would grab content out of document property, but it doesn't work.
