Function getUnparsedEntityNData()?

[Scott Sharkey <ss...@linuxunlimited.com>]

Hello All,

I've been handed an old xslt conversion program, and asked to make it 
work on Linux (originally compiled for SCO or TRU64 I think).  The make 
file with it specified Xalan_C_1_5_0 as the xalan lib, but I have not 
been able to find that specific version online in the archives (just 
xalan_c_1_5).

Compiling fails on the following line:

    const XalanDOMString& ndata =
              executionContext.getUnparsedEntityNData(name, *doc);

where executionContext is a parameter to the function, defined thus:

   XPathExecutionContext&      executionContext,

name is

   const XalanDOMString& name = arg->str();
          (arg is a passed pointer to an XObject)

and doc is
   XalanDocument* const doc = XalanNode::DOCUMENT_NODE ==
        context->getOwnerDocument()


It is saying that there is no getUnparsedEntityNData() function.  I have 
searched google and the archives for info about this call, but am 
getting nothing.  Was there such a function, perhaps now deprecated or 
refactored?  Any assistance would be greatly appreciated!

We've never released a version of Xalan-C called 1.5.0, so it would have 
to be 1.5, which you probably found in the archives:

http://archive.apache.org/dist/xml/xalan-c/source/

To my knowledge (and I'm the original author of Xalan-C), there has 
never been a function by this name. Perhaps the source code was modified 
and it was added? You might want to see if you can get Xalan-C source 
code that was used to build this application.

Since I don't understand what this function was supposed to accomplish, 
it's difficult to say how you can work around it. Perhaps the "N" in the 
name refers to a notation in the DTD:

http://www.w3.org/TR/REC-xml/#dt-notation

If that's the case, you can use the following function:

virtual const XalanDOMString&
XPathExecutionContext::getUnparsedEntityURI(
         const XalanDOMString&   theName,
         const XalanDocument&    theDocument) const = 0;

This assumes the "data" for an unparsed entity is the URI from the 
notation in the DTD. This function might also be designed to deference 
the URI, assuming it's a URL, and return the data from the entity, but 
that seems unlikely to me.

Perhaps if you can provide more information about how the ndata variable 
is used, that might help.
