Summary: dtdparser discards last line
Initial Comment:
The DTD parser in xml.parsers.xmlproc.dtdparser sometimes simply ignores the
last line of the input file. Here is the Python program I used to test it:
------begin
from xml.parsers.xmlproc.dtdparser import DTDParser,\
DTDConsumer, DTDConsumerPE
import tracer
def parse_dtd(dtd):
parser = DTDParser()
handler = DTDConsumerPE()
parser.set_dtd_consumer(handler)
parser.feed(dtd)
tracer.trace(DTDConsumer)
parse_dtd('''\
<!ENTITY % score PUBLIC
"-//Recordare//ELEMENTS MusicXML 1.1 Score//EN"
"t.dtd">
%score;
''')
------end
where the file t.dtd contained:
------begin
<!ELEMENT opus EMPTY>
------end
The tracer package (my own code) indicated that the opus element was never
parsed. The same was true if I added a blank line after the %score; entity
reference. However, if I added *two* blank lines after the entity reference,
the element declaration *was* processed.
I would note that while the bug exists in the original xmlproc package (at
least in xmlproc 0.70, downloadable from
http://www.garshol.priv.no/download/software/xmlproc/), the bug does *not*
exist in the PyXML package (downloadable from
http://sourceforge.net/projects/pyxml).
