Xsl:include support?
Xalan 1.5
Xerces 2.2.0
WinXP
VC6 sp5
I am converting our code from Java Xalan to C++ Xalan.
One of the things we use on every page is:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<xsl:value-of select="data"/>
</xsl:template>
<xsl:include href="/xsl?name=genericHead.xsl"/>
</xsl:stylesheet>
Specifically:
<xsl:include href="/xsl?name=genericHead.xsl"/>
For Java Xalan, I had to create a XSLTURIResolver.java.
When a xsl:include is found, the resolver tells xalan how to find the
genericHead.xsl document.
Is this supported in the C++ Xalan?
I have looked around the C++ API docs, but it is quite different than
the Java version.
Is there a sample that does this?
I grepped through the sample directory for this, but couldn't find
anything.
When I tried it:
XalanTransform.exe generic.xml generic.xsl
XSLT warning: Fatal Error at (file <unknown>, line 0, column 0): An
exception oc
curred! Type:RuntimeException, Message:The primary document entity could
not be
opened.
Id=file:///C:/OpenSrc/xalan/C/xml-xalan/c/samples/XalanTransform//xsl?na
me=genericHead.xsl (generic.xsl, line 7, column 50)
Error: SAXParseException: An exception occurred! Type:RuntimeException,
Message:
The primary document entity could not be opened.
Id=file:///C:/OpenSrc/xalan/C/x
ml-xalan/c/samples/XalanTransform//xsl?name=genericHead.xsl (, line 0,
column 0)
<xsl:include href="/xsl?name=genericHead.xsl"/>
It could be the format of the include, in this case it had to go to
http://localhost/xsl to retrieve the XSL.
TIA,
Dave
Here were the 2 files I used:
generic.xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<xsl:value-of select="data"/>
</xsl:template>
<xsl:include href="/xsl?name=genericHead.xsl"/>
</xsl:stylesheet>
generic.xml
<?xml version="1.0" encoding="UTF-8"?>
<data>This is a test!</data>

Much appreciated Mark, I have everything working as I need now.
Now I have to run some speed tests between the Java version and the C++
version.
Java is usually 10 times slower, so I am expecting to get some large
percentage.
Has anyone done this type of comparision already?
Thanks,
Dave

Here is a modified version that defines and installs an EntityResolver.
You will need to modify the resolver to suit; this one just returns a
URLInputSource for the URL:
class MyResolver : public EntityResolver {
public:
InputSource* resolveEntity (const XMLCh* const publicId,
const XMLCh* const systemId)
{
XMLURL URL(systemId);
return new URLInputSource(URL);
}
};
Any rewriting that you want to take place can be performed on the URL
object.

Hi Dave,
dumpbin.exe is your friend!
dumpbin /exports <filename>
dumpbin /imports <filename>
Do a dumpbin without any arguments for more info.

By the way, what tool did you use to find that you had that symbol?
I can't figure out which Microsoft utility will list the symbols in a
debug lib/dll.
Thanks,

Hi Dave,
You should double-check to make sure you changed all of the relevant
settings and that everything has been rebuilt properly.
XalanTransformer::setEntityResolver() is an inline function, so the release
build will not contain the symbol. In a debug build, the compiler will
likely generate an out-of-line copy, so you may have to change what
libraries you link against. My copy of Xalan-C_1_6_0D.dll _does_ contain
the following symbol:
?setEntityResolver@XalanTransformer@xalanc_1_6@@QAEXPAVEntityResolver@xercesc_2_3@@@Z

I just upgraded to Xalan 1.6 and Xerces 2.3.0
WinXP
VC 6 sp5
Besides changing the location of a couple of includes, I can
successfully build a Release version of my project.
I get compiler errors when I try to compile the Debug version of my
Project though:
Linking...
Creating library Debug/xalan16trans.lib and object
Debug/xalan16trans.exp
extXalandll.obj : error LNK2001: unresolved external symbol
"__declspec(dllimport) public: void __thiscall
xalanc_1_6::XalanTransformer::setEntityResolver(class
xercesc_2_3::EntityResolver *)"
(__imp_?setEntityResolver@XalanTransformer@xalanc_1_6@@Q
AEXPAVEntityResolver@xercesc_2_3@@@Z)
Some relevant points:
I have recompiled the XercesLib project for both Win32 Release and Win32
Debug.
These successfully compiled.
I copied the lib (release and debug) to the:
xerces-c_2_3_0-win32\lib
I copied the DLL (release and debug) to the:
xerces-c_2_3_0-win32\bin
Thanks,
Dave

Right, but where (what directory), do I create this class in:
entity resolver class.
Then what do I need to recompile to enable it?

You just need to call XalanTransformer::setEntityResolver with a pointer
to your entity resolver class.

You just need to call XalanTransformer::setEntityResolver with a pointer to
your entity resolver class.

RE: Xsl:include support - how to enable it?

Thanks for the response Mark.
I am new to all of this.
I read through the API documentation for the EntityResolver
(http://xml.apache.org/xerces-c/apiDocs/classEntityResolver.html).
It looks like it will do what I need it to.
In fact the sample code in the doc has:
****************
*#include <xercesc/sax/EntityResolver.hpp>
*#include <xercesc/sax/InputSource.hpp>
*class MyResolver : public EntityResolver {
public:
InputSource resolveEntity (const XMLCh* const publicId,
const XMLCh* const systemId);
...
};
MyResolver::resolveEntity {
if (XMLString::compareString(systemId,
"http://www.myhost.com/today")) {
MyReader* reader = new MyReader();
return new InputSource(reader);
} else {
return null;
}
}
****************
I would need:
if (XMLString::compareString(systemId, "http://localhost")) {
Where this breaks down though, is what are the detailed steps that I
need to follow to set this up.
Assuming I have Xerces 2.2.0 installed at:
C:\OpenSrc\xalan\C\xerces-c2_2_0-win32
And Xalan 1.5 at:
C:\OpenSrc\xalan\C\xml-xalan
What file do I need to create and in what directory to add this
override.
Does anyone have a complete .cpp code snippet that I can use.
Once I create this file, I assume I will have to rebuild my Xerces DLLs
(no problem).
After that, I am not sure how to enable the EntityResolver.
I am using the following sample that I have based everything on:
C:\OpenSrc\xalan\C\xml-xalan\c\samples\XalanTransformerCallback
So I am not sure where I need to put the code to enable this.
I am putting it in my XalanTransformaterCallback.cpp file?
If someone could provide me a bit of direction (and code if you can!)
here I would greatly appreciate it.
Right now I have everything working as I need it, but I am actually
copying the xsl:templates directly into the documents instead of using
the xsl:include tags.
Thanks,
Dave

There is an EntityResolver though -- you can create one of these and
provide an appropriate InputSource object. (These are Xerces objects,
so those are the docs you want to look at)

Xalan-C++ does not have the concept of a URIResolver. There have been
requests, but not enough resources to design and implement it.
