Description Brion Vibber 2005-10-20 02:55:38 UTC 
Distribution/Version: Ubuntu Breezy

When reading text node contents with the xmlTextReader interface, some lines 
with DOS-style line endings (\r\n) become double newlines (\n\n) in the read 
string.

1. Using xmlTextReader, read the attached sample XML file, which consists of 6-
digit numbers with \r\n end-of-lines.
2. Output the string value from the text node.

There will be an extra newline in output between lines 000063 and 000064. 
Extending the file, this will repeat every 64 lines (at 000127, etc).

Tested on Linux (Ubuntu Breezy) and Mac OS X, problem still present in CVS HEAD. 
Confirmed with raw C as well as Python and PHP 5.1.

Sample read & output using Python libxml2 module

Output from this Python program reading the sample file will include the extra
newlines. Equivalent program in C or PHP 5.1 does the same.

Okay fixed in a different way in xmlParseChunk() now.
