Hi everybody, and especially Uwe Schmidt et al. I ran into some problems trying to process some xml from a string source, illustrated in the code below. From file, using readDocument, everything works great though. I've probably missed a finer detail or two in the arrow handling, or it could be a bug in HXT (if I run the code in ghci, it will crash hard). Output: -->main.exe NTree (XTag (QN {namePrefix = "", localPart = "small", namespaceUri = ""}) []) [ NTree (XTag (QN {namePrefix = "", localPart = "xml", namespaceUri = ""}) []) [], NTree (XTag (QN {namePrefix = "", localPart = "example", namespaceUri = ""}) []) []] --> So it seems that the string gets read, since it shows up as a result from procString, but I get no output from writeDocument in writeStrDoc. Could anybody enlighten me? I'm using GHC 6.5 and HXT 6.0 on Windows XP.
