emphasizing a few additional keyword in a listing

hi all,

I have spend some days already to get a few keyword emphasized by color in a
listing. Here is what I am doing:

\usepackage{color}
\definecolor{Red}{rgb}{1.0,0.0,0.0}
\lstset{
	basicstyle=\tiny,
	commentstyle=\color{DarkBlue},
	stringstyle=\color{DarkGreen},
	emphstyle=\color{Red},
	showstringspaces=false,breaklines=true,numbers=left
}
...
\lstinputlisting[tabsize=4,language=XML,emph={style}]{./examples/styletheme.xml}
...
\lstinputlisting[tabsize=4,language=XML,emph={icon,fg_color}]{./examples/styledirect.xml}
...

I read the dvi for the listings package (v1.0 here) to no avail.
I've tried all sort of variations:
emphstyle=\underbar
or putting the emphstyle into the \lstset command
or even defining the words in the \lstset command.
Further I've tried putting speces around the word - nothing changes.

I have also grepped the ugly log-dump of the latex run (still wish latex could
do formated = parsable log output some day ;-) ) and there is no error in there.

has anyone ever seen this actually working?

Stefan
