I'm running Windows XP with the precompiled PHP binaries available
from windows.php.net. I upgraded from PHP 5.2.5 to PHP 5.2.16, and now
the <xsl:include>s in some of my stylesheets stopped working. Testing
each version in succession, I discovered that it worked up through
5.2.8 and does not work in 5.2.9+. I now get the following three
errors for each <xsl:include>.
Warning: XSLTProcessor::importStylesheet()
[xsltprocessor.importstylesheet]: I/O warning : failed to load
external entity "file%3A/C%3A/path/to/included/stylesheet.xsl" in ...
on line 227
Warning: XSLTProcessor::importStylesheet()
[xsltprocessor.importstylesheet]: compilation error: file
file%3A//C%3A/path/to/included/stylesheet.xsl line 36 element include

Warning: XSLTProcessor::importStylesheet()
[xsltprocessor.importstylesheet]: xsl:include : unable to load
file%3A/C%3A/path/to/included/stylesheet.xsl in ... on line 227
I presume this is because it cannot find the specified file. Many of
the includes are in the same directory as the stylesheet being
transformed and have no directory in the path, i.e. <xsl:include
href="fileInSameDir.xsl">. Interestingly, in the first and third
errors, it is displaying the file:// protocol with only one slash
instead of the correct two. I'm guessing that's the problem. (When I
hard-code a full path using "file:/" it fails, but when I hard-code a
full path with "file://" it works.) But what could cause that? A bug
in libxslt/libxml? I also found an apparent version mismatch between
libxml and the version of libxml that libxslt was compiled against.
5.2.5
libxml Version => 2.6.26
libxslt compiled against libxml Version => 2.6.26
5.2.8
libxml Version => 2.6.32
libxslt compiled against libxml Version => 2.6.32
=== it breaks in versions starting at 5.2.9 ===
5.2.9
libxml Version => 2.7.3
libxslt compiled against libxml Version => 2.6.32
5.2.16
libxml Version => 2.7.7
libxslt compiled against libxml Version => 2.6.32
Up until PHP 5.2.9, libxslt was compiled against the same version of
libxml that was included with PHP. But starting with PHP 5.2.9,
libxslt was compiled against an older version of libxml than that
which was included with PHP. Is this a problem with the distributed
binaries or just a coincidence?
To test this, I imagine PHP could be built with different versions of
libxml/libxslt to see which combinations work or don't. Unfortunately,
I'm out of my element in a Windows world, and building PHP on Windows
seems over my head.
Regrettably, I've been thus far unable to reproduce this problem with
an example outside my app, so I'm struggling to narrow it down and
can't submit a specific bug.
So, do you think it is caused by
* a version mismatch problem in the distributed binaries?
* a bug introduced in PHP 5.2.9?
* a bug introduced in libxml 2.7?
* something else?
I'm stumped. Any thoughts that could point me in the right direction
are greatly appreciated.
Thanks,
Clark A. Wise
