Description Anthony DeDominic 2018-08-01 19:22:33 UTC 
Description of problem:
how to reproduce:

#!/bin/sh
curl --silent --fail "https://en.wiktionary.org/w/index.php?title=test&printable=yes" \
| xpath -q -e \
    '//div[@class = "mw-parser-output"]/*/span[@id = "Verb" or @id = "Noun" or @id = "Adjective"]/ancestor::*/following-sibling::ol[1]/li'

Trying to parse wiktionary. messing with xpath just to experiment.
above seems to cause a problem. probably with how xpath buffers stdin?
when using a process substitution as an argument instead of stdin, it seems to work correctly.
