Using CLI Command to add hyperlink to a specific item?

Hello,

I just tried the following command:

im editissue --hostname=hostname.net --port=7001 --richcontentField=RQ_Text="<a href=\"http://hostname.net:7001/siro/viewrevision?projectName=%2%Programs%_selection=test.xml\">XML File</a>" 21020

But it doesn't work well. The created Hyperlink could not be opened.

In Addition I need to select a specific Version of the XML file. So I Need to add the Parameter "Revision" but how?

Thanks

C.
