Parsing gene expression value for a list of genes from GEO

Question

[Natasha]

Hello,

I am looking for the gene expression data in GEO with the following keywords,

(Pancreatic Beta Cells) AND "Homo sapiens"[porgn:__txid9606]

I would like to parse the gene expression value of a list of genes from all the samples reported in any particular study.I understand there are two different formats for downloading datasets, SOFT and MINiML.

From the files that I download, I wish to parse the gene expression value and the Sample Title and Sample Description so that I can classify the values based on disease state and control state. Any suggestions on which format can be downloaded for the above-mentioned task.

Are there scripts that are available to do these tasks?

Many thanks
