- make sure magpie can be found by PHP.
Usage:
Use one section between <rss>-tags for each feed. The rss section may contain parameters separated by a pipe ("|"), just like links and templates. These parameters are supported:
charset = ... | The charset used by the feed. iconv is used to convert this. |
short | Do not show the description text for each news item. |
max = x | Shows x most recent headlines. |
highlight = term1 term2 | The terms separated by a space are highlighted. |
filter = term1 term2 | Show only rss items containing at least one of the terms. |
reverse | display the rss items in reverse order. |
title = x | display an alternative title instead of chanel name. |
title = none | dont display any title. |
