In a Biztalk map, how can I execute a scripting functoid ONLY IF the source message contains a specific value? Which functoid combination can allow me to do this?
Edit
I want to check a certain element for a specific value. The scripting will be inline xslt.
In response to 40Alpha first suggestion: This is the method I would like to use but I can't connect the scripting functoid to the value mapping functoid. I'm probably doing something wrong here?

specific value... do you want to search all nodes in the message for a specific value, check a certain element for a specific value, or look if a specific element is present? - S1r-Lanzelot
