XML error when trying to read gexf

[JessicaFinck]

Didn't see this under the closed issues tab, so here we go.

I've constructed my networks on Python with sparCC, and saved them as a gephi project. For easier analysis, I want to load them into microeco, for which I need to import them into R and convert them to igraph.

Within gephi, I used the export command to save my individual networks as gexf files. I can open these files without problem with gephi. However, when I try to import them into R using read.gexf I get the following error:
Error in XML::xmlParse(x, encoding = "UTF-8") : empty or no content specified

This is my R code:
NW_bac_psr1 = system.file("bac_psr1.gexf", package = "rgexf")
gephi_bac.psr1 = read.gexf(NW_bac_psr1)

What could be the cause of the error?
