[Haskell-cafe] Use Haskell to extract GXL file (GXL representation)

[Sara Kenedy]

Dear you all,


Currently, I am working with GXL file (Graph eXchange Language). GXL 
is  a sublanguage of XML and  its syntax is based XML DTD.

In my work, I use GXL representation to represent a quantification:

 forall(x:Z|x = 3 and x^2 - 3x + 2 =0)

My objective is to write a Haskell module to extract the content of
the GXL file such that a computer algebra system (e.g, Matlab) or a
prover theorem (e.g, ICS) can read the content of GXL file.

Anybody
