Description Vasily Chekalkin 2005-10-27 09:55:23 UTC 
Steps to reproduce:
Sorry for report against old libxml2/libxslt1 version.

Report: libxslt can't parse stylesheet from copied doc.
Sample:

xmlDocPtr d1 = xmlReadMemory(str_data, str_len, "", 0, XML_PARSE_DTDATTR |
XML_PARSE_DTDLOAD | XML_PARSE_NOENT);
xsltStylesheetPtr s1 = xsltParseStylesheetDoc(d1);

xmlDocPtr d2 = xmlCopyDoc(d1, 1);
xsltStylesheetPtr s2 = xsltParseStylesheetDoc(d2);

After executing of this code I got "normal" stylesheet s1, but "zero" stylesheet s2.





Stack trace:

Comment 1 Vasily Chekalkin 2005-10-27 10:06:34 UTC 
I found place in which xml_error raised.

Breakpoint 2, __xmlRaiseError (schannel=0, channel=0x40b8fe14
<xmlParserWarning__internal_alias>, data=0x6380b5c8, 
    ctx=0x6380b5c8, nod=0x0, domain=8, code=1549, level=XML_ERR_WARNING,
file=0x0, line=0, str1=0x6380b560 "main.xsl", 
    str2=0x0, str3=0x0, int1=0, int2=0, msg=0x40c36140 "failed to load external
entity \"%s\"\n") at error.c:446
446                   void *nod, int domain, int code, xmlErrorLevel level,


This happend because I got in "read.xsl" imported file <xsl:import
href="main.xsl"/>.

Looks like in copied doc lost information about filepath.

"Sorry for report against old libxml2/libxslt1 version."

  Sorry I can't fix bugs in old versions. First retry with the latest ones
i.e. libxml2-2.6.22 and libxslt-1.1.15 !
  Then provide the full input reproducing the problem on the latest versions,
i.e. stylesheet, complete runnable test C program (with main() and compiling 
with gcc) and potentially the input XML data too.

  Back to normal severity and priority level because bug can't be asserted
on latest release and because it sounds not a sever problem.

Comment 3 Daniel Veillard 2005-10-27 15:02:29 UTC 
You *must* make the copy before the first compilation anyway. Compiling the
stylesheet is a *destructive* operation, it changes the input document.
