Package: xmlstarlet
Version: 1.0.1-2
Severity: normal
Using bash and dog, the following happens:
$ xmlstarlet sel -t -v /appliance/@name <(dog --no-header
http://garden.dachary.org/packaging-farm.xml)
/dev/fd/63:1: parser error : Document is empty
^
/dev/fd/63:1: parser error : Start tag expected, '<' not found
^
however, when using wc(1) it works:
$ wc <(dog --no-header http://garden.dachary.org/packaging-farm.xml)
14 57 1587 /dev/fd/63
strace shows the following:
open("/dev/fd/63", O_RDONLY|O_LARGEFILE) = 3
fstat64(3, {st_mode=S_IFIFO|0600, st_size=0, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =

read(3, "<appliance name=\"packaging-farm\""..., 16384) = 1587
read(3, "", 12288) = 0
