Re: Mathml XMLReader (starmath module)

Stephan:

The information I've gathered could be wrong. Collected it from code and searched in opengrok.

W3 says that entitynames can be introduced via DTD (but are not plain xml, or at least I understand that):

To incorporate the htmlmathml set into an XML DTD, a typical construct is:

       <!ENTITY % htmlmathml-f PUBLIC
         "-//W3C//ENTITIES HTML MathML Set//EN//XML"
         "https://www.w3.org/2003/entities/2007/htmlmathml-f.ent"
       >
       %htmlmathml-f;

However I had no idea LO supported it. If you could point me to it please ( could not find that dtd file in opengrok )? I may have been looking in the wrong place.

Stephan:

Mathml is not XML.

For some things it is a subset. For others not.

For example, character entities: quot, amp, apos, lt, gt. That it's all.

Mathml: &infin; ... matml specific ones.

With the information I've collected, this is handled by xmlreader.

Can not be implemented as xml. That's why I need to interfere with the xmlreader with a customized xmlreader.

The headache: it is hidden somewhere under a sea of classes.

For now I've been tracking code from (mathmlimport.cxx):

//Make a model component from our SmModel
uno::Reference<lang::XComponent> xModelComp = xModel;
OSL_ENSURE(xModelComp.is(), "XMLReader::Read: got no model");

But without any results.

Thank you for the hint.

I'm trying to make it work, but I keep getting "No source file named xmlreader." no matter how I enter the file path.

the easiest way to figure out stuff like that, is to run LO under gdb, e.g.

    make debugrun

set a breakpoint in XmlReader::handleReference with something like

   br xmlreader.cxx:429

where it throws the exception,

and examine the callstack using the

   bt

   up

   down

commands.
