[BioC] Exon ST expression data from GEO

Hi,

I'm wondering what is the best way to get expression data from a GEO
entry with the Affymetrix Exon ST platform?

For example, I've tried

> gse9342 <- getGEO("GSE9342")
> head(exprs(gsedat9342[[1]]))
     1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

^^^ no values are given.

I've also tried parseGEO() -> GSMList() on downloaded .soft files
which use GPL5188, but these also do not contain expression data.

Any ideas?

Thank you,
Jeremiah
