Description stephane.bidoul 2007-05-16 10:02:17 UTC 
Please describe the problem:
Hi,
 
I've discovered a strange problem with documents that have a long comment at the beginning (such as the attached a.xml). A slightly shorter header comment solves the problem (such as in the attached b.xml).

The problem occurs only with --stream. I can reproduce with 2.6.26 (cygwin) and the latest subversion code (win32).

Steps to reproduce:
~>xmllint --stream --noout --valid a.xml
a.xml:10: parser error : Extra content at the end of the document <!DOCTYPE a [
            ^
a.xml : failed to parse
~>xmllint --stream --noout --valid b.xml ~>xmllint --noout --valid a.xml ~>xmllint --noout --valid b.xml



Actual results:


Expected results:


Does this happen every time?

Okay found it, the patch is minimal but we have some horrible 
code in push mode to detect the end of the internal subset and
having a large comment or PI at the beginning of the XML.
I added a test case in the suite, commited to SVN head,
 
  thanks for the report !
