Can I Detect whether a node is *immediately* before the context node?

Hello, I am new :)

I have an XSLT query I could not find any solution to elsewhere. I need to
know if my context node is *immediately* proceeded by another node of a
certain type, in document order. So, ideally the test would return true for:

<foo></foo><context>I am here</context>

but not for:

<foo></foo>some character data<context>I am here</context>

Is this possible in XSLT or using a Saxon extension? Have I missed a very
simple solution? I would be extremely grateful for any advice!

Thanks,

Jamie McLaughlin
